Before the clouds moved in I took a few shots of NGC 7331 (Also known as Caldwell 30). NGC 7331 is the brightest of a group of about 6 galaxies in Pegasus. This image was taken over a couple nights around 1 week ago using the 16 inch Meade Lx200 at a focal length of 4096mm. Guiding was done via an off axis guider. The seeing was OK but not great and high clouds kept getting in the way. The image was constructed by stacking following exposures.

24 subs with the blue filter at 5 minutes each
25 subs with the green filter at 5 minutes each
27 subs with the red filter at 5 minutes each
51 subs with the luminance filter at 5 minutes each.

total exposure time 10 hours and 35 minutes. ZWO - ASI6200MM Pro USB 3.0 Cooled with the gain set to 100.
(All images where taken a -5C and in 1x1 binning)

NGC 7331 is spiral galaxy ~49 million light years away and has a Magnitude of 9.5
NGC 7335 and 7336 are unbarred spiral galaxies at ~332 and ~365 million light years away at magnitude 13.8 and 14.6 respectively
NGC 7337 is a barred spiral ~348 light years away and has a Magnitude of 14.6
NGC 7340 is an elliptical galaxy ~294 million light years away and has a Magnitude of 13.9

Other galaxies I found names for include
PGC 2051985
NGC 7325 This one is just above a bright star and hard to see
NGC 7326 This galaxy is Magnitude 15.87

Oops
NGC 7337 is a barred spiral ~348 light years away and has a Magnitude of 14.6 (That should have been ~348 Million light years away).

Here is a version with Ha added to the red channel. This redden the core of several galaxies and the arms to some extent, not as distinct a change as in M33 (See https://www.uglyhedgehog.com/t-714994-1.html). I also dimed the core in this version to see more detail farther into the center of the galaxy. Note: all these images where reduced in size by 50% to make them downloadable without cranking up the compression to high.

18 subs of HA added in each 10 minutes long (3 hours of Ha integration).

Great images, Ballard!
Wonderful detail!

Uh, nope. I don't have the focal length for that.

Hi SonnyE
Thanks for checking out the Caldwell C30 and the Deer Lick Group and for the comment. It is small and the longer focal length helps on this one. It is bit long for many object like M33 where it doesn't get the whole thing in. I'm working on an adapter to try and see if the .7x focal reducer for my refractor can be used on the Meade scope to get the field of view larger and the f stop smaller. Need some clear skies again, first smoke now rain with just a few weeks of moonless clear in between.

Absolutely stunning!!! I so much enjoy these great photogravures, being house bound, I watch for your work, thanks!!!

Hi DickC
Thanks for viewing Caldwell C30 and Deer Lick Group and for the comment. I really glad you enjoy the images. Taking and processing the images is a fun learning experience for me.

Well, your sure doing a good job!!

Compared to my earlier shots they are getting better. I think the best one so far was the first shot of Andromeda with the new camera. I'm still playing with the color a bit and may post it again with a few changes if they come out alright.
