You make an excellent point Sonny. Thanks to you I think I've discovered the source of why some of my images show elongated stars and some show round stars despite the fact that they are of the same exposure lengths. I haven't automated my processes yet so I found myself doing a lot of walking between the house and the telescope during exposures. I just didn't think about the vibration that my steps might send to the telescope but I think that's exactly what happened. Ahh...the learning curve....I don't suppose I'll ever venture onto a straight-away. BTW...do you have any recommendations for a good dedicated deep sky astro camera? I'm thinking DSLRs just aren't optimum for this sort of thing.

Sorry for being so tardy to reply.
No, I am far to narrow and inexperienced with Astro Cameras to advise on which one.
I can, however, point to the members here who have a great deal of experiences with a wide spectrum of different pieces of hardware, and wide ranges of far greater successes than I.
JimH123, Bwana, and several others here seem to collect different Astro Cameras, and use them successfully. I would recommend PM'ing them for specialized specific answers.
As a Po Boy I tend to take whatever is at hand, or my choice, then make a Silk Purse out of a Sow's Ear.
For my simplistic approach, and my lazy ways, the Atik Infinity has proven to be stellar for me. (No pun intended
) I can usually tell if a given night will be good, or poor, for imaging. Poor nights are often used for practice or fine tuning, if not just ignored.
But not being able, or willing, to buy and try a myriad of offerings, I take what I have then wring out the last drop of capability of it. The G III was a marginal choice in bottom end cameras. But I did manage to eek out some pictures with it until it finally died altogether.
Many of my Friends here on UHH tried their hand at the data from the G III, but most realized it was just too crummy to work with.
I do admire the work I see presented by many here with their choices of equipment. Some amazing imagery! But my capabilities are to take the bottom end, then do my best with it.
But I have a great deal of fun along the way.
Many of the new "Hot Ticket" Cameras are, as I expected, CMOS type of sensors. CMOS is overtaking the tried and true CCD types. What I was watching and waiting for was the CMOS to come out with cooled sensor versions.
CCD's have been cooled for years now. CMOS's are finally coming of age, IMHO.
I am, and remain, a Post Processing Minimalist. I don't like manufactured images. I did not like Photo-shopped pictures in the 1990's, and don't like re-manufactured images today. But the razzel-dazzel crowd seems to.
A prime example is the well known Hubble Telescope images. They are, or were, all Monochrome (Black and White) images. Then they were colorized by laboratory processes. The colors were manufactured into them.
Kinda pops the bubble for me. I can't believe what I'm seeing in the image. I can say you can find
thousands of examples of green moons on the Internet. But you will never see one looking up at it.
So my choice is to get it right in the camera, with a color matrix, and to do as minimal of PP as I can.
If you do choose to use a Monochrome sensor and filters, you do need to also consider focusing for each filter change because you are putting a different element into the light entering the camera. So for that, best to consider an electronic filter wheel, and an electronic focuser.
I built my own electronic focuser and control it remotely. Ronnie and I collaborated about remote operation and he helped me become a WiFi Astronomer. My laptop was my outside computer. But when it died, my "new" Baby Dell 2-in-1 computer now does that detail. And being a late generation, it does WiFi much better than my old laptop did.
But I like being able to run everything at the mount with the Baby Dell to do alignments, or do a
Tight Vnc connect and have a virtual screen indoors.
If you'd like help doing a computer control for a mount, I'd be happy to share what I know about it.
But it stops the walking around the mount, and can give you fine focusing control without contact with the mount at all. Cool as a pocket on a shirt.
