Re: [Utah-astronomy] IC443 H-alpha Image
Nice image Tyler! Are you going to go back and get the RGB information or just leave it "as is"? There are lots of H-alpha targets in that area of the sky. Debbie

Hi all. During our last clear night, I tried imaging IC443 with an Astronomik 15nm bandpass filter. This object is a supernova remnant with a suspected neutron star. The neutron star is perhaps only 20 kilometers in diameter, but has more mass than our sun! I was only able to get 4x10minute exposures before it went behind the trees in my back yard, but it is a good start. I am very interested in doing more H-a imaging, because it can be done when the moon is very bright. Use of this filter will allow many more opportunities for imaging without worrying about a bright moonlit sky.
I hope someone enjoys the image.

Debbie, I would like to finish an RGB image, but it all depends on the weather. Right now, I would be happy just to get enough info to smooth out the Ha image. I think it probably needs three times the Ha data to really make for a nice smooth image. The RGB exposures could be much shorter. The problem is that it is getting lower in the evening sky and the weather won't cooperate!
