How do I configure the "Best of stellar serie" function ?

If the actual number of selected images is left in the field "max number of final images", this function then keeps images verfying the fact that have a FWHM X/FWHM Y ratio lower than the value entered in the "FWHMX-FWHMY max" field on the interface.
If the content of the "max number of final images" field is lowered, and if a high value (100) is put in the "FWHMX-FWHMY max" field then the function will return a batch containing the best images.
The function then adds the prefix best_ to the returned images

How does the Realignment of a stellar images batch work ?

The function runs through the following steps :
1 ) A batch of images is selected using the selection tool
2 ) The first imge of the series is loaded and stars are modelled, and then for each of the remaining images :
3 ) Images are loaded and modelled, and stars positions are registered to the reference image
4 ) A linear regression (least squares) function is called in to calculate the transformation function parameters and its uncertainties
5 ) If uncertainties calculated before are lower than what s specified by the user in the Config/PreProcessing window, then the image is realigned and saved with the rec_ prefix prepended to its name.

What is the spy file ?

TeleAuto logs every action and function returns into a text file at \spy.log\ . This is helpful to the development team, and helps debugging quite a bit.

What s the Geometry/Stellar realign by morphing about ?

This funtion realigns images of the same object that were acquired using different telescopes/cameras/focal length/sampling. It will detect all stars in the images, register them, and then performs a polynomial morphing on the second image, so the second image is similar to the reference. It is then possible to blink the 2 images, for example.

Can I do color imaging using TeleAuto ?

Yes. It is possible to save images having different color layers into one single image file, (FITS for example). Most of the arithmetic and filtering functions are fully compatible with this scheme. The exceptions are :
- FFT (complex multi plane images are not yet supported)
- Inter and AutoCorrelation products
- Geometry/Realign
Also, the preprocessing routines are not yet supporting multi layer images.

TeleAuto can t find my catalogs...

Catalogs have to be installed into the \cat\ folder. The exceptions to this are the 'big' catalogs such as Tycho, GSC, USNO.
Valid catalog folder names are NGC, PGC, RC3, WDS etc.
Moreover, TeleAuto has to be configured acording to where the catalogs are on your system. You can check your configuration by looking at the System/Configuration window. Correctly installed catalogs are listed there.

The Prism Cpa v4 Image format is not recognized ?

TeleAuto can recognize the following image formats :

• CPA v3
• CPA V4d

TeleAuto crashes when starting

You can check if the TCP/IP stack was detected on your system. Check the spy.txt file to ascertain this.

I can t connect my telescope

When the telescope is not connected, the scope pad toolbar button and the corresponding menu item are both grayed out. TeleAuto automatically scans your system at boot time, looking for your telescope. In case it finds one, you then can call the scope pad by clicking on the toolbar button. If you connect your scope, or power it up *after* TeleAuto has started, you need to select Config/Connect Telescope. If an error occurs and the scope is still not detected, then you might want to check cables and try again.

My images are showing too much/not enough contrast at acquisition time.

This can be set in the System/Configuration window, on the threshold panel. You can change the hi and lo cuts of the image there.

What s the best method for using the image selection tool ?

Double click on one of the image files displayed on the left, and all files in this directory will then be selected.

How to use the automatic preprocessing window ?

You can manually select images using the procedure desribed above. A button can select images matching the generic image names entered in the config, such as "dark" or "flats".

How does the stellar realign function work ? A least squares regression algorithm is used int it. This allows to use all available information contained in your images.

What s the use of the "Max realign error" parameter in the automatic preprocessing function ?

During the realignment process, TeleAuto knows what the position uncertainties are for every star that was detected on the image. This parameter is used simply as a rejection parameter, to allow you to automatically reject images that would impose too big an image shift.

How does TeleAuto knows the position and flux of the stars in my image ?

Our detection function uses a wavelet extraction, and our modelling function uses the Levenberg-Marquadt non-linear least squares algorithm. The latter tends to avoid solutions that converge to ridiculous quantities, which is not necessary the case of standard linear regression models.

How do I change languages ?

You can change the language using File/Change languages. If you wish to translate TeleAuto into another language, then 
you can create your own : File/Create a language, File/Edit a language, File/Update a language. These are using the base language contained in model.lng
You can have a look at english.lng or model.lng to understand how it works. If you do that, then please let us know !

How come my bmp's get these funky psychedelic colors ?

When you are loading a bmp file, process it and save it, the saved file will contain the new bmp color palette will be saved along with the image data...
You can try to select an existing teleauto palette using the image thresholding tool. This happens because TeleAuto considers the bmp format as it considers the other images formats.
