I went outside at 8:30PM, dressed in the above, with the temperature a balmy 54F. Nice. I could take a whole summer of that. I brought out my 80mm on its CG4, 10"
I did a tour of the eastern sky with all three scopes as the Moon moved out from behind the tree to the south. At about 10PM and 50F, I tried for some pics of the rock with my 80mm. Those came out pretty good, then I looked over at my 10". I wonder....
Well of course it won't come to focus with my
I should probably take pics to better explain what I mean; if you want I can provide some
Anyways, I took about 20 pics like that. I didn't have the remote shutter connected to the camera at that point, which would really have been the idea. And holding the camera still wasn't easy as well, it kept sliding around. By now the temp was 48F, and I was thinking it might be time to swap the T for a sweater. Ah, it was damp out as well, and at midnight it started raining.
So here is my point. I thought the pics with the 10" would be a lot larger than the ones in my 80mm. But I forgot about focal ratio's. The 80mm is
I used the same processing settings for both in PIPP, making the output frame size to be 2400 X 2400.
This is the 80mm:
And this is the 10":
Not a huge difference, size wise, and the frac has more detail, but the camera was solidly mounted to it. Not so the 10"....
I did the math, and I'd have to cut 2 inches off the back of the 10" to move the mirror up for
Those of you on here that know me well also know I'd have no issues about doing this either
The question is: Should I? It would take about an hour to do, and I have everything I need waiting to go. But I'm wondering if I'm overlooking anything regarding using it after for visual. Would an extra 2 inches on the focuser narrow the field of view dramatically? I don't need it to be as narrow as my Towa 3"...
Any advice would be greatly appreciated!
All the best,
