Helix Nebula NGC 7293

My old desktop finally gave out, and I had not backed up the original files of this shot so they are lost forever. But I do have a low resolution version saved which is displayed here.

Next time I'll shoot this at a longer focal length to get more image scale.

Canon 350D modded
Astronomik CLS light pollution filter
Takahashi FSQ-106N @ f/5
