Here's a new one, the Jellyfish Nebula. Officially named IC 443 or Sharpless 2-248. It is a large supernova remnant in the Constellation Gemini.
About an hour of total exposure, 500mm, f4, ISO 1600, tracked with a Losmandy G-11, stacked in Deep Sky Stacker, processed in Images Plus and Photoshop CS4.
And here's an old one, but a new image. Horsehead Nebula. By stopping down the lens 1/2 stop, I can make
diffraction spikes on the bright stars. The bright star in the center is Alnitak, in Orion's Belt. Some like this, some don't. I like them.
The Heart Nebula. It is so big I can barely fit it in the frame. It is difficult to frame something this big when one can't even see it in the viewfinder.
I have to take a long exposure, see where it is, adjust, try again. Didn't get the detail I was hoping for. I probably need more exposure, this is 45 minutes total.
