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 due tu the gibbous moon very poor!!
so I tried to compensate a bit but not fully satisfied with the result.
Nevertheless globally the RASA8 with 100 minutes per channel has a very good efficiency. so let's see what could be the result on other deep sky objects!!
Rework details on SHO version + crop added
HOO version added also.
