Thomas,
I quickly look at the FITS file, the stars are very small probably because of the sampling of 3.6"/px.
The "Image inspection" button detect 10x more stars if in Preferences / Focus the option "System is undersampled, accept 1 pixel star" is checked.
With this option you must be sure to have a good bad pixel map or a good dark loaded in CCdciel to prevent to focus on hot pixel.
Can you try with this option if you have the time tonight?
|
|
|
|
It shall be clear tomorrow, I will take a dark and use it as bad pixel map and retry
The image inspection function detect even more stars than autofocus when "System is undersampled, accept 1 pixel star" is not checked. |
|
|
|
Autofocus use only the stars near the image center and your image has very few stars in this area. We not want to focus with star in the image corner.
Also when the image is defocused to measure the curve, the fainter stars may get a too low SNR to be taken into account. This is because we not just need to "see" the stars but we need to measure their diameter at half flux with a good confidence.
I am interested if you can also save a FITS image of the defocused field in the same condition it use for the first point in the curve. |

Thanks for your fast reply. It helped me much. Now I took the slowest methode, 1x1bin and 12s exposure. Than much more stars were recognized as stars and autofocus is much more reliable. Important were I go asleep.
>Autofocus use only the stars near the image center and your image has very few stars in this area. We not want to focus with star in the >image corner
Consider to mark this area with a rectangle. |

Thomas,
Your FITS file is very interesting because it is just at the limit of undersampling but not really undersampled.
I make a change to the program to accept more real star in the image and still reject hot pixel.
https://github.com/pchev/ccdciel/commit/9e795fd473f7a6e6161438e2fd97dde109d02f5f
You can install a test version with this change from:
https://vega.ap-i.net/tmp/ccdciel/
You can probably autofocus successfully in bin 2x2 with this version.
The area stars are taken for autofocus is the square that contain the larger bull eye circle. For a quick check you can just count stars inside the bull eye. |
|
|
|
Forget to say: with this new version be sure to disable "System is undersampled, accept 1 pixel star" so hot pixel are rejected. |
|
|
|
Oh that's great. I will test ccdciel_0.9.69-2151 tonight.

Hello Patrick,
for me this was a great improvement. More stars and shorter focus time.
I would be glad if this will come in the next official version.
Thanks for your efford.
Thomas

Hello Thomas,
This is very good news!
Sure this will be in next version, probably soon.
The log show that many stars are used at every step of the focusing and the curve is nice.
In the out of focus frame the star SNR is low. The star detection and radius computation is still good but you must be careful to no more defocus and not use shorter exposure time.

Just for info. Yesterday I got my ASI183 back from china, it has a thermal malfunction and has to be repaired. With this camera autofocus is fun. Also the test version which I got from you works fine too.
Look how fast the complete autofocus with 7 points is:

Hello Thomas,
Was this test with or without the OIII Filter? I assume without.
I have opened a second topic regarding the hotpixel detection with Patrick.
Question how do you judge the light sensitivity of the the MI CCD G2-8300 used for the sample file in comparison with the ASI183?
Han |
|
|
|
No, this was with a RED filter and should not compare with my Moravian CCD. Besides it was with another scope!!! It should demonstrate, that the new focus improvement does not harm with cameras with a greater resolution and how fast it can be. Really great.
Sorry both equipments cannot compared, sorry.
After all, the performance of the ASI183 is unbelievable.
Thomas
PS: Han I think we met 20 years ago at this funny place. You held a presentation about HelloNorthernSky |
|
|
|
Yes that correct, I visited the "Deepsky Tagung". I have been there twice with an astroclub member of the Bonner Verein. :) I was living near Bonn in those years. Now I'm back in the Netherlands.
With my question regarding the camera, I was as trying to understand if your problem was a rare case or something which should be addressed in the program code. It should have no unforeseen side effects. |
|
|
|
I do not think that is a rare case.
Telescope: 8" F/4 Newton (reduced to f/2.9)
Camera: Moravian G2-8300 with KAF8300 chip

|

Thank you Thomas for this test with the other camera.
Yes the autofocus is fast when you can use this short exposure time. |
|
|
|
Thomas,
Han proposed a new way to improve this processing: https://www.ap-i.net/mantis/view.php?id=2307#c6440
The star detection work even better with your test image, both focused and defocused.
I make a test version with this change and we are very interested if you can test the autofocus with the 183 or 8300 camera.
Install from: https://vega.ap-i.net/tmp/ccdciel/ |

My equipment is running at the moment. Tomorrow there is a change that the first half of the night would be clear. I will test this new version. Thanks for development. |

Hello Patrick,
sorry I was not able to test it with the Moravian . This is the last clear night and I use two scopes in the moment. My other Laptop is windows and I was not able to get the filter names of my moravian filterwheel in CCDCiel....an other story.
I have tested your new version with the ASI183 but I cannot really say that there is an distinct improvement, maybe slightly.
A comparison is not easy. The log of a autofocus yesterday and now is not much different.
The sceenshoot shows a H-Alpha frame at the begin of the dynamic curve (focuser max out). Only one star is recognized, this is harmful.
Filter Blue, same field:

Hello Thomas,
The focuser reaches a HFD of 16.4. With the relative weak H-alpha signal this is too far from the focus position at around 4.1 and I would reduce the step size such that you reach a HFD of maybe twice the minimum so 9. The step size is 120, so I would reduce it to 60 or 80.
The dynamic focus method doesn't need to be in the linear range. It can work in the low range of the focus curve which is an advantage for focusing using small band filters.
Something similar is written at topic "Dynamic parameters"
https://www.ap-i.net/ccdciel/en/documentation/preferences#auto-focus

Reaching a HFD of 16.4, the SNR signal is still very good at 215. Is the minimum SNR set correctly? I can't look to my settings but a setting between 5 or 10 will fine. See attached screenshot: |

Thank you for the test Thomas.
The change Han make to the code make it safer for other kind of images with different sensor noise. I want your testing only to be sure there is no regression with your camera. But I am really confident it will work because of the many test we do with the images you provide.
About the single star detected on the Ha image, can you look at the Preferences/Focus what is the value for "Star detection window size".
From this screenshot but also the small number of star show at start and end with the blue filter, I suspect it is too small.
The value is set for bin 1x1 and is adjusted for current binning so it not need to be changed when binning change.
The star HFD is 17 at bin 2x2, this make 34 at bin 1x1, so the value must be at least 60 preferably 80.
If you load such a defocused image in ccdciel you can try to adjust this parameter and use the button "Image inspection" to see the change in the star detection. |

I had a look to my setup. I have put the minimum SNR at 6. For H-alpha I set the exposure time at 7 seconds. The SNR's I see while focusing are varying a lot but with the H-alpha in place I see SNR values between 15 and 200. So lower then your SNR values which vary between 206 and 274 . But you exposure time is already as short as 3 seconds and I would not reduce that since shorter exposure time will introduce more variation in the HFD due to seeing effects.
So reducing the focusser stepsize and checking the minimum SNR setting should fix your problem.

Hello Han, hello Patrick,
thanks for all your effort.
Tonight, before your answers came, autofocus failed with filter green. I instinctively did what you suggest. I reduced the step-size a little bit (from 120 to110) and it worked better. Fortunately CCDCiel saves focus_fail images.
I loaded that image in ccdciel and pressed image inspection. Only two stars were found (StarInspection of failed focus image 2020-03-29 12-20-08). Autofocus found none tonight and breaks away. In the log (StepSize reduced.txt) you see both focus attempt with 120 and 110 step size. I am asking me, why are the two central stars of that image not recognized as stars? Maybe because they are rings caused by my diagonal mirror?
As attachment my recent settings. Are there any faults?
At monday or tuesday there is the chance of getting clear here.

I am at a window size of 250px at the moment. I did not know that these parameters are used for ImageInspection also. If I vary image inspection window from 60 to 250 with the focus fail file I got weired results.

Thank you for the focus fail image.
250 is probably too much for the star detection window, a too big value may make some stars to be rejected because another nearby star make perturbation to the measurement.
I make some test and yes the new rejection for hot pixel is responsible for not using more stars because of the star ring.
We tested that a least 3 pixel are above noise near the star center, this is not the case in your image because the ring is well defined.
By removing the test with distance_histogram[1]<3 I get more stars as show in the screenshot.
We see there is now one hot pixel wrongly selected because of the removal of the test.
There is also two portion of star ring that give wrong value of 5.7 and 3.9. This is because the Auto-focus "Min-SNR" value was 7 in my setting, changing it to 16 remove this two wrong value and also the hot pixel.
Maybe this is the way to go?
Can you try with this values:
Star detection window = 80
Autofocus tolerance Min SNR = 16 |

Thomas,
Patrick is correct that the hot pixel detection fails here since there are no pixels illuminated in the center due to the donut star shape. So it doesn't work in CCDCiel.
The de-focused stars are still very large (total diameter 30 pixels) and the illuminated pixels rise just above 3*noise level even with a SNR of 120. All focus problems will be solved if you reduce the step size from 120 to 60 or 80 and defocus up to HFD 9 only. This will increase the signal for each illuminated pixel with a factor 4.
Patrick,
I agree that an SNR of 16 gives better result to filter out some hot pixels/false detection's. Maybe it is better to increase the default SNR value which if i'm correct at 5.

Hello,
thanks for the reply.
In the next clear night I will try the following settings:
Star detection window = 80
Autofocus tolerance Min SNR = 16

You need a CCDCiel version without the introduced hotpixel detection since that doesn't work for the donut shaped stars. If Patrick doesn't issue an update, you better use an older version which shows 4 or 5 star detections in your image:

Thomas,
you can get a version with Han fix for the stars with central obstruction, please use this one for further testing:
https://vega.ap-i.net/tmp/ccdciel/
The higher SNR limit is probably valid for CMOS but with my CCD it work best between 3 and 5.
The ideal solution is if we find a way to estimate the best value part of the focuser calibration procedure.
Maybe when at a medium defocused position we can vary this value to minimize the HFD dispersion but still get the most star as possible. |

I got it. I will try it even the moon is at first quarter and high on the sky. The sky should be clearing.

Hello Patrick, hello Han,
I am testing 0.9.70-2165 in the moment and I can say it works quite good. I commented the logfile e.g what filter was used.
The profile change error is not tested at the moment.
Screen Capture: Bildschirmfoto vom 2020-03-31 21-20-50.png
shows autofocus with a L-Filter. Nearly all stars were covered, great
Screen Capture: Bildschirmfoto vom 2020-03-31 21-19-20.png
shows autofocus with a OIII-Filter and 120steps (to much). But I clearly see further two stars which are not recognized.
I have another wish. The user cannot see or control the window in which autofocus is working. Can you draw a rectangle on the screen while autofocus is running. I've got a 12" Newton with a big 120cm diagonal and a good coma corrector. To increase this autofocus field can be done without any problems.
I recorded my screen during autofocus with the red filter.

PS:
I got some nasty devices logs which I cannot cancel in the INDI Driver dialog. Can you help?

Hi Thomas,
It can be interesting to see the FITS file corresponding to the 21:19:20 and 21:20:13 screenshot to see why the star left of the galaxy center is not selected. This is the only one that can reasonably be added in this images without extending the search area.
Otherwise from the log the big difference with the different filter is the peak intensity on the first defocused position and the relation with the number of star:
step 80:
B: peak=3664 nstar=13
OIII: peak=1356 nstar=2
step 120:
OIII: peak=1136 nstar=2
L: peak=12052 nstar=17
On the previous focus_fail image of the same area the background level is at 688, this make the OIII maximum star intensity only 668 and 448 above the background.
This let me think the OIII filter exposure factor is set too low, by doubling the exposure time and use step=80 you can probably get 6-10 stars.
The square of the search area is two third of the image height. I think this is good for square or 4/3 sensor format, but with the wider 3/2 imx183 this make the search area too small.
I can make a change to use the full sensor height for sensor wider than 4/3.
I can also add an option to use the full sensor area when the optic allow that.
You must disable all this debug information send by INDI, this is to debug the driver themselves and even in this case this must not be send to CCDciel because this can impact the performance.
To disable the debug, start the INDI server, open the INDI client from Indistarter or CCDciel.
For each driver, at the Option tab uncheck "Driver Debug" in both "Debug level" and "Logging level". Then click Disable on the Debug row.
Finally click Save on the Configuration row.
Then stop and restart the INDI server, look at each Option tab that Debug is still Disable. |

One point more about the star intensity.
A level of 448 above the background can look good.
But we must remember this camera use 12 bit ADC, this make the full ADU range from 0 to 4096, then the driver multiply each value by 16 to go in 0-65535 range.
So the real ADU of the maximum intensity in this image is 448/16 = 28. |
|
|
|
Thomas,
I do the change to increase the star search area with wide sensor and add an option to focus with star on the whole sensor.
This is new version 0.9.70-2167 :
https://vega.ap-i.net/tmp/ccdciel/
The new option is in Preferences / Autofocus, when "Stay in place" is checked you can uncheck "Use only star near the image center". |
|
|
|
The weather is still clear here in southern germany, we also must stay at home. So I can test this version. Thanks for developing.
I have tried to stop DEBUG excactly as you discribed, but it does not work.
Thomas

Strange for the INDI debug.
Can you edit the file ~/.indi/EQMod\ Mount_config.xml when INDI is not running.
You must see :
<newSwitchVector device='EQMod Mount' name='DEBUG'>
<oneSwitch name='ENABLE'>
Off
</oneSwitch>
<oneSwitch name='DISABLE'>
On
</oneSwitch>
</newSwitchVector>
If not try to set Enable Off and Disable On, save the file and start INDI server. |
|
|
|
Thanks for the reply. OK I looked into when Indi is not running. Here is the file, I think it is OK, but it debugs over and over again. Is it possible that Indistarter does it, because I updated it to 2.2 some days before? |
|
|
|
The change in 2.2 is the option to connect to the device as soon the server is started. Do you check this auto-connect column?
To be sure you can try the following, start the server from the command line:
indiserver indi_eqmod_telescope indi_asi_ccd indi_moonlite_focus
Start CCDciel, select the menu Edit / INDI setting, and look for the Debug value. |
|
|
|
Ok I will do this tomorrow, because Holmberg 124 is running.
I can say that I am very satisfied with the current version. The expanded field covers much more stars. There are screenshoots and a focus file.
1. Autofocus increase field.png
is the screenshot to the Focus-file.fits
2. Autofocus perfect curve.png
is the result. I like it
3. Autofocus incerased field Image Inspection.png
I loaded the focus file into ccdciel and did an image inspection. -> Result: other stars as by the autofocus routine. One star at the right corner (middle) is not covered at all.

No problem with Indistarter, it happend again when starting from command line. |
|
|
|
Thank you for the testing and the files.
I think I see why it get less star in autofocus than in image inspection. I try to fix that now. |
|
|
|
The problem was the star detection window not adjusted during autofocus, it was doing that only on the first startup frame.
This is fixed by:
https://github.com/pchev/ccdciel/commit/8630e9a66c0c865d1ca9eba7e04f2fe7763b8efa
The new version with this change is 0.9.70-2168 :
https://vega.ap-i.net/tmp/ccdciel/
Now it must measure all the same star in autofocus, the selection in "Autofocus increase field.png" must be the same as in "Autofocus increased field Image Inspection.png" |
|
|
|
About Indi debug, what is the Indi version you use?
Personally I use Eqmod from Indi 1.8.4 and never get this issue. |
|
|
|
This issue does not come after an update, it comes without reason.
I think I got the latest stable.
I use your next test version if the sky clears again.

Hello Patrick,
tonight I am testing version 0.9.70-2168. With my equipment autofocus with the expanded field is good. I am satisfied.
I attached a focus file. It is the file before 1.png. Sorry I cannot save so quick. There are to bright stars in the upper right, which were not detected most of the autofocus process. Strange, the last point of the curve (most defocused) the star is recognized (see 2.png). In the final image (3.png) the two stars are not recognized again. If I press image inspection, they will.
This is only informational.

Thank you Thomas for this new test ad the clear explanation.
I do many test with your image focus.fits this morning and find why in some case the two bright stars in upper right are rejected.
The problem is because of the asymmetry of the star image as show in attached screenshot.
When the detection is done using the stored central position there is too much bright pixel out of the measurement window that prevent precise HFD measurement and make the star to be rejected. ( for Han: test ri>=rs at cu_fits.pas line 2723)
This can be solved by adding a small margin to the computed measurement window.
https://github.com/pchev/ccdciel/commit/efccc397c8e23e54398652d9b75e205c52d57ec4
Apparently "Image measurement" is not affected by this problem because of the way it scan the image with overlap between pass.
A new test version 0.9.70-2170 with this change is available for testing:
https://vega.ap-i.net/tmp/ccdciel/
Personally I use the previous test version for 3 night without problem, a pity that this big moon spoils the best sky of the year. |

Hello Patrick, that's good.
I agree, there are not trails from airplanes at all, the sky is very blue. Normally Germanys sky is horrible polluted with airplanes.
I got this new version for tonight. Thanks for building.

Patrick,
I had a look to the two stars. The star profile is indeed a little strange. The base is faint but wide. The star radius ri is measured for both stars 5, so a diameter of 10. The actual base is wider up to 15 pixels but there is not much flux in the outer regions. At the moment I have no idea if this is caused by the seeing or the optics.
I'm considering several other options to detect them.
1) Exporting the ri from TFits.GetHFD2 is one possibility but it measures 5 so that doesn't work since it should be 7 or 8.
2) Experiment with the drop-off detection in TFits.GetHFD2
3) Your s:=s+4
4) Change line 620:
- s:=min(max(12,round(2.5*med)),s); {reasonable window to measure this star}
+ s:=min(max(14,round(3.0*med)),s); {reasonable window to measure this star}
The HFD of the two stars is 3.5 and 3.8. So only the boxsize of 14 probably will fix it.
For ASTAP, I also have this 14 as default box size. Does this 14 result in detecting these two stars in the focus routine?
Tomorrow I will have an other look.

Looking to the screenshot, the stars are not round. As Thomas described the two stars where not detected at most of focusers steps. This indicates the problem is not cause by the seeing but by the unroudness of the stars. Only increasing the detection box over the whole range will fix it. So the factor 2,5 is too tight and didn't consider unroudness. I would suggest to change it as follows:
- s:=min(max(12,round(2.5*med)),s); {reasonable window to measure this star}
+ s:=min(max(14,round(3.0*med)),s); {reasonable window to measure this star including oval/unround stars}
The unroundness will decrease at higher HFD values. That's why the detection worked in the last step.
That will result in this:
HFD | Boxsize
____________________
4 | 14 (28x28)
5 | 15
6 |, 18
20| 60
|

Hello Han,
Yes, using 14 and 3.0*med look like a good compromise.
It still detect all the star in "why not more stars.fits" and detect the smallest of the two stars here, only the bigger is not detected.
I need to increase the box to 16 to detect both stars, but in this case some close small stars in "why not more stars.fits" are not detected because of the double star check.
So I think we can stay with this change:
https://github.com/pchev/ccdciel/commit/c53f237de663da92f0f1777397fad185cd9ee512
Now I look to publish a new version with all this change, the 0.9.69 is two month old and there was a lot of improvement done in this time. |
|
|

I am very happy to have a expanded field for autofocus. At the moment I did PK164-31.1 under full moon. Autofocus with OIII is set to 8s and there are enough stars to focus. Thanks for your efford.

Thank you Thomas.
I close this issue now before the release of the new version tomorrow
I you have the time, I just add two new text to translate for the PHD2 graph and guide statistics.
