I heard the Astronomik UHC filter lets through Halpha,O111 and H beta all in one. So I thought I would give it a go.
Sbig 2000XM, William Optics 80/480 triplet, TV.8X flattener/reducer, NJP mount, CCDSoft, Images Plus.
3 x 5 minutes at 24C (desiccant needs replacing, frosting occured as soon as I cooled it, surprisingly little noise though).
The main point here - it was a full moon! And from my backyard, so I am very happy with that.
Looking forward to doing that again at a dark site and also shooting some colour.
