Here is Saturn Nebula (planetary NGC 7009)
I am now working on the color response of this new NTech camera.
This is a single snapshot of the view I was seeing tonight. ZERO post processing.

Here is the blue snowball in color. ZOOMING your browser reveals some really nice structure. Again a single snapshot of what I was viewing. ZERO post processing.

Awesome, John! What scope and exposure? There seems to be little noise and the stars don't have the blocky look that my Sammy often produces.

Your really getting that NTech dialed in John. I'm curious on how a longer integration time through a filter would do, but those planetaries look great.

Dan, I was using my Orion 12" Goto. No filters were used, which surprised me as with the Samsung I usually do. The snowball was done at 256 integration, Saturn Neb at 512 with both at AGC set to high and through a 2x barlow. I am finding that under exposure setting that WDR set to 1 is really knocking down the noise. Also of note the 3DSNR was NOT in use for these captures.

Thanks John!
It has been quite a learning curve but it is now starting to look like it will be a good investment.

Excellent work- thanks for this. Couple of questions- have you had any problems switching back and forth from day/night: Color/B&W? Mine is still stuck even after a factory rest...also just curious about your not using 3dsnr- any particular reason you are not using it?

It did seem to have an issue trying to go back to "Day" after shooting in "night" . However when I initialized the camera back to factory default the issue went away. I have left it in "day" since then.
I did not use 3DSNR last night as the images were clear enough and noise free enough as to no use it. Also I do turn it off (if it is on) whenever I change objects or have to tweak with focus. The 3DSNR slows down the image update and on can cause overshooting on focus and creates more time when trying to frame an object. I will use it if needed, but I find that with the setting and results I am seeing that it is not always needed.

Well I finally got out to my parents home and the skies there are very dark. (West Texas). I was trying to get in some video before a storm that was due in by 10:00 pm. By the time I got set up and the video running I only had time for the lagoon and a couple of others to follow. The skies were so dark the Milkyway was casting a shadow. No moon and no artifical, man made, light source! I only had time for the Lagoon. It could have been better but I was really rushed to set up and tear down before the storm hit. I did catch some of the winds when I was still tearing down the scope. I did get the mirrors covered which was a good thing as it was a sand storm preceeding the coldfront and we were still packing in 50MPH winds!
Anyway here is the lagoon with the hourglass. Screen shot of the lagoon with the new NTech Mini camera through my 12" Dob in very dark skies.

Here is NGC7331. It was starting to get breezy. I did not do much to try and improve on this one. I think I could have gotten more detail but was already starting to take things down to get ahead of the approching storm.

A few from last night. We finally have some good transparency here. However, these were from my backyard so I had to fight some light pollution.

GF1 90 Seconds ISO 800 with Orion Sky Glow filter. Single shot out of camera jpg. I used the 2x crop mode so this is actually the equivalent of 1600mm F4.0. Since these cameras have so much resolution it really doesn't hurt much to use it in crop mode.

Travis,

Nice images. You're really starting to pull some nice color and detail out with that camera using longer exposures. Isn't it interesting how the Orion filter cuts down the background noise.

I am fairly happy with what I am getting now. I haven't located any object that I have tried to see that I couldn't. Well except the HH which I am confident I will be able to see when it gets a little higher later this year.

I like the Orion filter. However, I ordered an Astronomik
CLS Light Pollution Filter to compare the two.

I have heard so many good things about the Astronomik that I wanted to try it as well.

I also used an Astronomik "L" filter last night. It doesn't cut out the sky glow or LP. However, it removes the IR and UV light that my full spectrum camera sees. That improves the image over no filter considerably and then I can keep my exposures shorter.

I estimate that the "LP" filter looses about 1 stop of light over the "L" filter. However, it allows me to get about 1 stop of extra contrast. Not too bad.

The thing I like the best about the setup I have is that it is so easy to align, focus, and find objects in near real-time. And I leave the entire telescope and mount setup all the time.

I simply carry the whole thing to my backyard and start imaging after I align.

Here is the result of adding an Astronomik CLS Light Pollution Filter.

M27 AT8IN 105 Seconds ISO 800 single exposure. I still need to work on the color balance but not bad considering this was in my backyard and I still am working on my tracking issues.
