files size change with same camera settings

Post by cjacobson » 18 Mar 2020, 06:07

I am a long time user of AA since version 4. Now using 6 and 6.2 to run my starlight xpress m25c camera. Last night I imaged with it and downloaded images of file size 12021, tonight with same settings it would produce image size of 11942. I restarted the software several times. doubled checked for binning. I ran this both as an Ascom camera and using the AA drivers.
None seemed to make a difference. What is wrong??? the file size is usually 12024kb. thanks cjacobson

Maybe there's a difference in the FITS header? The most important thing is the size in pixels, did it change?

No change in pixel size. Oh boy, I know what is the difference with your promt. the array size changed a bit between the two nights.!!! that's the reason!!. I thought I had checked this when i first noticed the difference. Will re check again today. thanks cjacobson
