My First Proper Ha/HaRGB Image

[Stub Mandrel]

I got 90 minutes of 5-minute Ha subs of the Bubble nebula last night, here this, and then put together with 63 1-minute RGB subs from last year. Clearly I need a bit more practice, but the improvement over last years RGB image is noticeable, there's a lot less noise and much more detail in the Ha from the cooled camera, far more than can be explained by the 50% extra time.
