Hi, I am going to give ASTAP a go with point craft in the program Astrophotography tool ( APT )
I was just going through reading the download information / instructions for ASTAP
It was talking about installing either the H17 star database or the H18 Star Database
It then goes on to say:
Select the H18 if your FOV is less then one degree
So i am just a tad stuck on trying to figure out what by actual field of view is.
I have been playing around with astronomy.tools calculator to try and work things out, but i think i might be miss reading the information.
My scope is a Skywatcher Evostar150ED
Camera is ASI2600MC
Using the imaging tab with all the details entered i get a figure in the field of view of 1.12° x 0.75°
So sorry for going over what i guess must be the basics, but from this would that suggest that i would be best of going with the H18 Star database?
Just as i am a tad over 1 degree in one way but under in the other.
Any advise would be appreciated.
