Thanks...I had to compress it to fit it on the forum...so the real time view was actually a bit better.

Nice image. That's closer to what I see at 5-7 seconds using a Mallincam with more aperture (a C11) under less than great skies (mag5 and a Deepsky filter). I need about 15s with my C6 for that kind of image.

My skies are very clear right now...and it is very dark. Come mid June though the Arizona monsoon will shut me down until September. I used to live in Kentucky. Even the darkest and clearest nights were no comparison to the Arizona border region. I adopted and discarded astronomy in KY several times.

My first set of experimental images of the MallinCam X2 with an unguided 10" LX200. First time I have ever seen M51 like this through ANY telescope. I need to learn the tools a bit more, however I am having fun with this!!

Good first effort. What really helped me was learning the controls in the codec for contrast, brightness and so on that are on the PC you are recording it on. My black and white camera even has sharpening controls built in to it.

Yeah,

I discovered a few more controls last night that had a profound change on the image. In addition this was taken at f/5. Right now I am in the learning, exploring and having fun mode (well this is always fun!). Tonight I will be experimenting on a new telescope - a 14" LX850. Images might be slightly improved.

I am slowly learning this bugger, the MallinCam X2.

Here is a set of images comparing from the 10" LX200 and the 14" LX850. NOTE on the LX850 Images they do not use Starlock. Why you ask? I forgot to take off the LENS COVERS, GRRRR! When I finally figured it out and played with it, the clouds rolled in (of course!). Still, the basic tracking is EXCELLENT!

Andrew,

Nice images ... fun isn't it?

Remember that you are also comparing f5 vs. f4 optical trains as well as the larger aperture. The majority of the density in your images is probably from the difference in f ratio (but all the extra stars in the M57 image are from the extra aperture ... and likely cleaner brighter optics).

When you are poking around M57 you'll find it fun to look for the extra stars (not just the center one) inside M57 as well as the close by galaxy IC1296.

Hello Mark,

Yes it is clear the comparison of f/5 vs. f/4 and the larger aperture is a one-two punch. And yes, the optics of the 10" LX200 are 22 years old!

My family and I had a lot of fun the other night looking at the sky. The main comment from my kids - it looks just like in the books! Yeah, it is not the fancy multi-hundred stack images, but seeing it "live" like that is fun and educational. Some of it looked nice in the ep, but nothing like the MallinCam.

This is a very addictive combo. And I can see this functioning as a powerful learning tool. It really hits home!

I am getting a handle on the scb-2000. So far 512 sens-up has seemed pretty useless, but once again using m104 as a test subject I paid close attention to my alignment and finally got a good video of it but with a few abberations. A little more work on my tracking and I will have it. This is a grab.
M104 6" SCT, scb-2000 camera, 512 sens-up. All my recent images are at f5.

That's a very good image for a Sammy at only 10 seconds. Your tracking doesn't look too bad, the slightly defocused stars are quite round indicating pretty good tracking. Better focus will get rid of the doughnut effect.

Edit to correct the integration time for a PAL camera

Thanks. It is a PAL version so I think I am getting maybe 10 sec. I do see the focus off now that you mention it...4 of the stars have doubles which I accounted to tracking. Maybe the scope moved suddenly (maybe I bumped it) and it left a double. I just ordered the LN-300 to play with 1024x. These cameras will keep me busy until I got the cash for a Mallincam or comparable camera. I just blew a lot on a scope so that may be a while...

Looking good so far Atl.

Weird how only some of the stars are doubles from movement. The top double is actually a double, so it is only the 2 right near the galaxy (one directly above and one to the left) that have the double image from movement.

But yeah, focus is way out. Once you get that sorted it will be a fantastic capture.
Well done

I finally managed to get a half decent sky last night so I conducted another NightSkiesNetwork 'Southern Hemisphere Sky Bus Tour'

Here are a couple of Screen Grabs from my broadcast, using a Mallincam Xtreme, 0.6x FR, ED80 scope.

Wait, what? There was a Snake Valley broadcast and I missed it. Drat.

Must remember to keep an eye out for the next one ... perhaps if we were forewarned of these rare events?
