Gina Posted June 18, 2021 Share Posted June 18, 2021 3 hours of Ha and 2 hours of OIII. Taken with dual WF imaging rig with 200mm f4 lenses (Asahi Super Takumar SLR vintage lenses) and ASI1600MM-Cool cameras and Astrodon 3nm filters. Guided with 200mm lens and ASI178MM camera. Ha exposures 600s and OIII 1800s. Calibrated with flats and darks. Processed in PixInsight. Hoping to capture more data when we get some clear night sky in the new imaging season! 6 Quote Link to comment Share on other sites More sharing options...
