Binary system galaxies M77 and NGC 1055
One of the first results from my outing on 8 Nov 13.  A pair of galaxies that compose a binary system approximately 60 million light years away.  M77 is at the top of the image with NGC 1055 at the bottom.

Full size/details:

Vega...and others
So, this was a test shot just before imaging a few objects on the night of 8 Nov 13...right after I took all of my equipment to the backyard, setup, polar-aligned, focused, etc.  Vega was the second of three targets to align the mount with (to get accurate "go-to" slews when going to the objects I am going to image).

What were you doing 25 years ago?  Well, this is what Vega looked like about 25 years ago as it is roughly 25 light years away.  Very bright, so the test with 10min subs have it really over-exposed :)  However, can see some galaxies in the surrounding of this frame if you look hard enough.  This shot was 2x10min Lum frames and 1x5min each RGB.

I am also including the Lum filter only result to better show surrounding objects.  Note that in this test shot, Vega was not "perfectly" centered, so the optical dim ring around the star is not perfectly centered when looking at the Lum/mono image.  On the positive side, each corner shows perfectly round stars from edge to edge in the 2048x2048 uncropped image with these 10 minute frames :)

I am still working on the data for the other objects, so this is just to give you something new to look at in the meantime :)

NGC 281 - Pacman Nebula (in HaRGB)
Here is the last object from the night of 28 Sep 13.  In fact, I had a short amount of time before the sun rose, so just slewed over to this object without really thinking what kind of result I would get (object dimensions, etc.).  The last few subs I didn't use as the sun was coming up : )
