So this is my first attempt at imaging (“First Light” as they say) with my one shot color CCD, the QHY10 camera. The Great Orion Nebula was my target tonight. I was certain something wrong since I couldn’t figure out where the color was, so I quit after only capturing 36 minutes of data. Now it’s time to start learning better post-processing techniques. I also badly need a coma corrector. Here is more information:

Great shot.
What camera you normally use or prefer, the ZWO ASI1600 or the QHY?

These QHY's really preform well at that price point. Looks like your new mount is performing well as well.

Hi Chuck thanks for sharing your experiences. I have the qhy10 as well but really haven't had a chance to use it much since my available time to capture is limited. I noticed your gain/offset values and was wondering which method you used to get them? The manual gives you a way to get them, but I have found a more scientific way to get them at this website.

I tried them both but get very different values. I'm using 5gain/120offset right now.

Pretty nice result, I also did a new LRGB of M42, way better than last time: http://puu.sh/tWGQe/27397b97b5.PNG

Interesting… Never thought the mono ccd would be THAT much more sensitive. The other thing you have to think about is zwo claims like 90% qe so ya, I don't understand why more people don't buy the 1600mm

Very nice Chuck!
