8/14/2020 The Lagoon and Trifid Nebulae in Narrowband

Friday evening was a good evening at the River Ridge Observatory. Other than continuous lightning in the east that turned into nothing but lasted until about 2 AM, the conditions were pretty good. I stayed and imaged until 4:30 Saturday morning. This will be the first of a few posts about my results.

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.
