Here is the Ha image by itself.

I took a lot more Ha than this but I made a few admin errors and they were imaged at 4x4 binning rather than the intended 2x2. I probably would have imaged it at 1x1 usually but I only had one night left and I wanted to get the RGB as well.

The peak of the tower would make a good imaging target for a longer focal length scope. Those ridges and sharp bits usually look good in long focal length images. Perhaps the CDK can get that area by itself.

Greg.
