Finally last night I was able to conduct some Ha imaging testing. The test object was Eta Carinea. The Moon was just a couple of days past full and about 95+ degrees away (on the Azimuth) from Eta Carinea at the start of the run. The scope used was the Skywatcher MN190, which at f5.3 is relatively fast, and it is well baffled (something I thought would be important on a night full of moonlight). The camera sensor was cooled to 0C during the test. I shot 8* 300" lights, and dithered between subs to enable processing out of the bad column in my sensor. I used BYEOS and Metaguide and was surprised the dithering worked so well, just select Metaguide on the setting page and press the button. I think I left all the other dither settings at default. Shot Darks, and Bias Frames after the Lights, and then did the Flats this morning at dawn. Stacked in DSS, and the Hot and Cold pixels were removed along with any evidence of the bad column. I checked the Flats and the bad column can clearly be seen, and I have a bright pixel in the Darks but all of this was removed by DSS (and dithering of course).
I have attached a jpg below, and remember it is small for posting here and honestly the quality is not great in this little file. The larger version is up on Astrobin here, and I recommend you look at that instead of the little one:

In processing with Photoshop, the only thing done was some Auto Levels, I am sure there is room for more work there.
Pretty happy with the image detail, the Fits version really leaps out of the screen. For a limited test run of just eight subs I think it (the camera) is working pretty well and I am pleasantly surprised with the Ha gathered on a very bright night.
Comments and feedback/suggestions welcome.
