Here is the Keyhole Nebula in H-alpha.
William Optics 80mm fluorite triplet, Sbig 2000XM, Schuler 6nm H-alpha, CCDSoft, Takahashi NJP mount. The WO matches the Sbig chip quite well for a good image scale. I can also use a TV .8X field flattener/reducer and will do another one to see if it makes much difference. 4 x 10 minutes.
Any comments on the processing? I used CCDSoft and the changes it can cause are dramatic compared to the other styles of processing I have used on DSLR shots.
Also shot some colour for this but still processing that.
Greg.
