So last Tuesday night I obtained my first two image sets of M42 (Orion Nebula, the trapezium region) using my 6SE, ZWO ASI385MC, with a Astro-Tech f/6.3 reducer. It was actually the "first light" as well for the 6SE. I used the ASICAM from a link at the ZWO website for the AVI video capture and AutoStakkert for the aligning on a DSO. After that I was informed that SharpCap is more often used on DSOs. So next time out SharpCap it is.
The 1st set was a 180s video using an exposure of 770ms and a gain of 450. Same 180s video with exposure and gain for the 2nd image of 100ms, and 600 respectively. It was around 25F out and the sensor temp was close to 4C. The second image set was set up to have a bit better defined stars and you'll see slightly less overlap of the fours bright stars in the image center. There was also less drift of the image for 2nd set but the video certainly shows more random noise and hot pixels. AutoStakkert seems to have removed the hot pixels or very much minimized their presence in the final image. Overall I prefer the images obtained from the first video capture.
Anyway, here are the two images fresh from AutoStakkert and after some fairly straight forward post-processing with Photoshop. I can't say I'm all that happy with the blown out stars but it appears that using SharpCap may take care of that. The Photoshoped ones show more detail and nebulosity but I think are more grainy. I prefer the photoshoped ones showing more of the nebulosity and a bit more detail...
