Yep, another one!
Here is 1.5 hours worth of 7 nm hydrogen alpha, taken in 30-minute sub-exposures.
Just a quickie put together in MaxIm DL with a DPP/log stretch, and saved to JPG in Photoshop CC.
I had a couple of sub-exposures before the crack in my sensor appeared. So, tonight's 30 minute offering didn't contribute too much to the crack.
I had a massive win tonight with my guiding. I turned the aggressiveness right down to 1 for both X and Y in MaxIm DL and I was getting a pretty much perfectly smooth guiding graph with 6.8 second guide exposures (CCD Commander automatic guiding enabled). I previously used to have it at 8, then, tried 4, and 3. Even 2 was too much. The two prior exposures had very slight trailing, but, I included them in my stack, anyway, just to see what would happen. Tonight's 30 minute addition had absolutely perfect round stars. I'm so stoked.
