IC1848 HOS


IC1848 HOS

Narrowband using SVX140T w/SFFX-2 flattener (F/6.8 at 952mm). Taken with QHY600 and 3nm Optolong filters. HOS to RGB 4-hours total (16x each). 300s unguided exposures at mode 0, gain 60, offset 35, 1x1, 0C. Was my first test with Optolong NB filters. May shoot more NB exposures if weather cooperates and add some RGB (for better star color).
