As mentioned in an earlier post, I set up my 11″ Elf with the Hyperstar so I could shoot at f/1.9 and added an Optolong L-eNhance filter to the setup. This filter blocks most light but lets the reddish Hydrogen-alpha line, the blueish Hydrogen-beta line, and the greenish Oxygen III through so that your color camera can still do RGB photography. I used my ZWO ASI294MC Pro.
I’ve shot the Eagle Nebula before, just a couple weeks ago even, but I think this is my best so far. I don’t think I’ve ever shot the Helix or Crescent Nebulae before so it was nice to have them come out this well.
