Attaching the NGC 7331 image so that the higher resolution is available.

Thanks, Jeff. It is amazing that we have such fine equipment available to us. And it is only going to get better.

I suspect you think of this too, but I am commonly amazed that the quality of what we can get with our relatively small scopes rivals the best images from the huge scopes and facilities at, for example, Mr. Palomar, a few decades ago. In this case you even got the shot through cloud cover. In the NGC 7331 image, you got good quality images of 7335,6, and 7 as well. I was just looking at some of the pre-CCD images from there and this is of similar quality. 

Thanks for sharing, Willie.

I went out last night to assist with the Baylor group if needed and conditions were quite variable, high clouds of varying thickness all night.

But I took 7 x 120s of each of the following using the Luminance filter and the ProEM camera on the 24” telescope.  Then I processed them with bias, darks & flats before enhancing with Photoshop CC.

I was pretty impressed with the result considering the sky conditions.

8’ x 8’ is the FOV of the ProEM on out scope.

Excellent. The ProEm camera gives a larger image than the CTAS camera.

An attempt to attach the NGC 891 image so that the higher resolution is available.
