FITS Header standard

naz_david

Is it intended to eventually make the FITS header compliant with the standard like the ASIAir? I am particularly bothered by the fact that neither ASIImg or ASILive include the filter type in the header. This makes it a pain to manually allocate groups of files to the right filter in third party processing software such as Astro Pixel.

naz_david Thank you for the suggestion！
Will add "include filter type in the filter header" to the to-do list

That would be much appreciated! It would be good to include image type (IMAGETYP) as well as filter type (FILTER) - both are readily available.

The only other that would be handy is instrument focal length (FOCALLEN) but that would require a manual input to be added to ASIImg and ASILive and probably not worth the bother.

naz_david Could you tell us why image type (IMAGETYP) and instrument focal length (FOCALLEN) are needed and how would they be used when post-processing? It would help us understand the importance of these headers and add it better to the Studio.🙂
Thank you in advance!

Honestly I just compared with headers from files produced when I was regularly using an ASIAir Pro and these were the only ones missing in ASIStudio files that looked like they might be handy for sorting at a later stage. No use to me at present for what I am doing - the most important is the filter type and I very much miss that one.

naz_david Thank you Naz, will feedback to the team.😉

The other option to get the instrument focal length (FOCALLEN) in the header would be to include plate solve in ASILive!

ASIStudio@ZWO

naz_david Noted.😉 Will also add "plate solve in ASILive" to the to-do list.

The other thing I have noticed is that XPIXSZ and YPIXSZ are incorrect - they should be the image pixel size which of course is the binned camera pixel size. The plate solve software I use expects this and I checked and the ASIPro fits header expresses them correctly (and even says in the comment "pixel size in microns (with binning)").
