Re: Will the Mach 2 support .....

Thanks for posting John. Very nice image.  Even taken in a fairly light polluted environment it came out well.  Images like this make the decision to move away from a OSC camera more difficult.  Glad to see you’re able to image unguided with your Mach1/130.

The following is my post to our clubs Facebook page. (Texas Astronomical Society of Dallas) An example of fairly fast image acquisition with a OSC CMOS camera. I'm trying to get efficient with my time as I'm getting older.

From my backyard in Allen, Texas:
MPSAS 17.8-18.2 / Bortle 8-8.2 (Measured with SQM meter)
Finally got the results of my science project I've been working on for the last 3 months. Did not spend more than 2 hours on the work flow today... not including stack time. This is not an attempt at narrowband with shrunk or no stars, but rather a composite RGB image from a OSC camera with colorful background stars. Did spend a month or so on refreshing my math for sky background vs sub length calculations and doing a boatload of testing with filters and my SQM meter.  
63 subs @ 240secs (4.2hrs)  LeXtreme Pro
156 subs @ 30 secs (1.3hrs) Hutech LSP P3
Total integration for my Bortle 8+ sky was 5.5 hours. 
Can probably cut the broadband down to about 35 mins of 30sec subs for a total integration of 4.8 hours. Anything more doesn't improve the image for me. This will allow me to shoot more than 1 nebula per night sometimes depending on their brightness, but IC443 is fairly dim.
