Heart Nebula and Fish Head Nebula taken with my new wide field setup : RASA 8" and ASI1600MM
Taken in a dark sky location in France with a very good sky despite gibbous moon. Ha shots were quite good, but OIII and SII due tu the gibbous moon were quite bad (OIII) and quite poor (SII)
Nevertheless globally the RASA8 with 100 minutes per channel has a very good efficiency.
Details reworked on Ha shots (100 minutes - 50 shots) and crop added on melotte 15 and fish head nebula.
