Hi Odille
Nice shots!
I created a “Field Of View” indicator in Starry Night Pro Plus 6 for a 300mm lens based on a formula from Michael Covington’s book “Astrophotography for the Amateur”.
The FOV came out as 4.2 x 2.8 degrees and this is what it looks like with Saturn and Lulin in the frame. Good luck with the photos!
Cheers
Dennis
