Re: ASTAP FITS file

Hi Han,

Just a brief update.

Dustin has very kindly modified the nova.astrometry.net api to provide the image size in arcseconds.

I've now got my app producing an image Focal Length that is independent of pixel size.

Cheers, Jim

Re: ASTAP FITS file

Hi Han, Once again, thanks again for your thoughtful posts. :) If I followed your first post, then I think it came to the same as my initial conclusion. I agree completely with your second post. I don't know why I didn't think of it before, as I only mentioned in a post to someone a few days ago! :r...

Re: ASTAP FITS file

Hi Han, Once again, thanks for the quick and comprehensive explanation! :D I wondered if it was part of the resolution for the performance issue. I guess the answer for what I want to do is to build a multiplication factor into the calculation? i.e. focal_length = 206.264806 * pixel size / pixel sca...

ASTAP FITS file

Hi Han, I use the APT/ASTAP integration feature to produce a FIT file when APT does a Platesolve2. The process works brilliantly and doesn't seem to add any time to the solve process. However, there seems to be a difference between the construct of the original ImageToSolve.jpg file and the created ...

Re: After APT > ASTAP/PlateSolve2 - increment filename of created .fits file

Hi Han, Ruedi, Thanks for the comprehensive reply! :) I guess I was just being lazy! ;) By getting ASTAP to (optionally) increment the name it would just save me closely monitoring the folder. :D I'm slowly getting my head round the Mosaic process - so thanks for the extra tips. I'll have to think a...

After APT > ASTAP/PlateSolve2 - increment filename of created .fits file

Hi Han, I saw your post in the APT Forum about using ASTAP to write a PlateSolve solution into a .fit file ( http://aptforum.com/phpbb/viewtopic.php?f=17&t=1678&e=1&view=unread#unread ). I followed your instructions and it worked perfectly. :D This got me looking at HNSKY. Again, with a bit of resea...
