Hi and thank you for reading this
I mounted a secondary scope piggy back on my C14 comprised of a 61mm William Optics refractor and an ASI1600MM Camera. This System is producing 62 Megabyte science images AFTER I process through Astroimage J.
How do I reduce the FITS size below 50 megs so that I can upload to Vphot?
Thoughts?
Thanks!

Hi Pablo,
This is a 16Mpix camera. Assuming 16bit resolution, each image should be 32MB in size.
AstroImageJ must be producing floating-point images. Check and see if there is an output option to use 16-bit unsigned integer. With your 12-bit ADC, 16bits is more than adequate for storage.
Otherwise, the only options are to either bin 2x2, or else use a subframe that only contains the variable and its comps.

Thank you Arne, I fixed it by selecting 16 bit on AstroimageJ and all is well!
Thanks!
