Summary0002041: OBJECTRA FITS keyword can generate malformed entry
DescriptionFound this problem when using MPO Canopus to automatch (plate solve) an image. The strict FITS formatting requirements require 2 characters for the RA, e.g. hh:mm:ss[.ssss] or hh mm ss[.ssss] . For RA < 10h CCDCiel apparently places a blank space for the first 2 RA characters, e.g. 4, while it should be 04 (see attached FITS header). The blank space causes MPO Canopus (and possibly other programs) to fail in a plate solve.

Would it be possible to add a leading 0 for RA<10h?

Many thanks!!
