Abell 21 (Medusa Nebula) And NGC 2395
      #5803633 - 04/16/13 10:20 PM

This was imaged from 12-11-12 until 04-13-13

I'm not really sure the HA data improved this image much. The data from the red channel was quite good already, and adding the HA seemed to mess the color up a bit, but I didn't want to waste the data. Overall I think it did help to bring out the fainter areas that might have been lost in the mild skyglow I have to overcome. Thanks for looking and please let me know what you think. I couldn't get an image under 100k and still keep it half way decent looking to post in here so please just click on a link to see the image.

Excellent. Most would overlook that star cluster. Though it is in the Herschel 400 list.

I have to agree. The first thing that struck me was the star field. The colors in the stars are really nice I enjoyed cruising around the star field more than looking at the object itself.

Very nicely done!
