I was playing around with my Canon 60Da last night through my Explore Scientific ES127 ED Triplet. This is a 20 sec exposure, no guiding and playing around with Photo Shop CS5.1

Looks great! Really pretty picture!
When I downloaded, then zoomed in I can see minor star trailing.
Might be from activity around the camera during the capture, or from natural earth vibrations at your location.
I'll clarify.
When I was finally beginning to get pictures with my telescope, I discovered that if I moved even the slightest, it would tell in my image. I was quite surprised how just moving my foot on the concrete walk could show in my image.
That is one thing we can control. Don't move, and even slow your breathing to a steady state while the camera is open. Consciously focus on being as still as possible near the camera. Or stay completely away.
Try it, you'll find as I did it will make a difference.
Natural vibrations are something we have a lot less control over. Those are things like traffic on the street, or even induced vibrations. Our neighbors tend to slam their car doors hard enough to vibrate small things in our house in the corner near their driveway.
If you can, do Live View, and better yet, Live View with the view displayed on a computer. Watch the image closely and tap or stomp your foot. Watch for vibration in the view.
That is one of the peculiarities of Astrophotography. The camera never lies. It records everything that happens during the collection of the image. Even atmospheric shimmering.
Taking a series of images, then stacking them, allows you to manipulate out bad or less desirable frames.
You ARE off to a great start though.
Orion is the reason I'm in this mess. He sucked me into wanting to image Nebula. One peek at the Great Orion Nebula through my spotting scope and I wanted more.

Nice job, careful or you will get sucked into the dark side.
You mentioned no guiding, but you were tracking? a 20 second exposure should be able to use tracking only. you maybe off on your polar alignment. Once you get that nailed down, then you will want to start stacking. The stacking will help to increase the SNR and your photos will get very clean (no noise).

I think you're right about bad polar alignment. I just got this CGE mount and a plate to mount the refractor to it. Just a quick setup, with rough polar alignment to. I will probably be using my C11 Hyperstar most of the time, but was testing mount/camera compatibility and seeing how quickly it sets up with the refractor.

Have you used the 11” Hyper? I have a RASA. Pretty amazing.
I used to have a Nexstar C11 with the carbon fiber tube and a Hyperstar lens. I regret selling it and am saving my pennies to get another Hyperstar lens for this OTA. I have never seen a RASA, but I know someone using one, and they love it.

20 sec only? Wow! What were your camera settings? I use the same Canon 60da, which I really like.
