TFOV question

[miguel87]

I had no idea what the TFOV would be like when using my DSLR at prime focus on my 200P. After my first pictures last night I tried to replicate my view on stellarium.

Problem is, it is suggesting 1.333° x 0.5° and that ratio seems all wrong. Surely it is closer to 6:9?

I want to know so that I can plan what I am framing better.

Thanks

Hi Miguel,

The Stellarium graphic shows a fov of 80 arcmin X 50 arcmin, which is an aspect ratio of 1.6 to 1.

Think my brain is a bit slower after tearing down my setup at 2am.
