About LinkBacksI moved over to the SCT on Friday night to take advantage of its smaller FOV during galaxy season. This is a three night integration of data (approximately 1-1/2 hours total) taken with the SCT with both the Canon 60D and the Atik 383. (Some of the data is from February 2015 taken with the DSLR)
I combined the data using Nebulosity's align, rotate and scale feature.

Re: The Bodes Galaxy (M81), three night integration
Nice detail and color, John. Was taking three nights to get 90 minutes of integration time the result of dodging the clouds, the Moon, the sky placement, some combination of all of these?

Re: The Bodes Galaxy (M81), three night integration
All of the above. I cannot view most objects as they rise in the east until they are about 1 hour away from the meridian
. Besides Thor's Helmet (different thread), I was after some views of M106. It did not get high enough to image until around 1am, so Bodes stood in the gap. The images taken Friday were by far the best behaved that I have ever taken in the region. I have always had trouble getting PHD to calibrate and many other issues associated with poor polar alignment in the past. Friday's images were deeper looks with most of the frames being taken at 300s and one at 600s. The data from the previous years were around 60s each at a fairly high ISO.
One thing that I liked about the previous data is that the DSLR is more sensitive to the Ha and Hb data than the other channels and causes this to be highlighted. I purchased a new MotoFocus remote focuser for the SCT that arrived on Saturday. So, I'm hoping to be able to tweak the focus during the imaging session as I can with the MoonLite on the other scope. (I have read that SPG doesn't care for central obstructions in its auto focus algorithm, so my setup will use the focus remote manually.) (The temperature dipped to 17°F Friday with the humidity climbing to 89%). As such the initial focus on the Atik was a little laborious to dial in.

Re: The Bodes Galaxy (M81), three night integration
John,
Great color and framing. Looks like the focus is just a tad off.

Nice detail and color. Boy I thought I had tight constraints at about 2 hours per night

Re: The Bodes Galaxy (M81), three night integration
Looks great. I agree the focus is just a smidge off to my eyes. Keep em coming!
