Description

Taken from Bortle 6 skies in St. Pete, FL. Dew control is no joke!

I believe the Optolong filters (Ha - 7nm, OIII/SII - 6.5nm) might be missing most of the data from the shift at f/2. I'm wondering if the Baader highspeed set the only way to go. Maybe I need to change how I capture OIII/SII? Does anyone know any alternatives?
