Thanks so much!!! That was great!! Love the visuals!! Does the secondary mirror actually extend the standard focal length? I mean if it was a flat secondary mirror it would be a shorter focal length, right? Doesn’t the quality of the image get worse with each reflection too?
Thank you.
Well explained and simulated. Thank you !
Wouldn’t the secondary mirror look like it’s in the way, making a hole in the center of the field of view?
