Description

Large Field taken in January 19th and 22nd with my RASA 8" .
Medusa Nebula area is quite a challenge to process.
Still some halos on the 2 Gemina stars, due to the combination of F2 + narrowband Ha filter and ASI1600MM camera.
Ha taken with ASI1600 (4h30m and 54 shots of 300seconds)
RGB taken with ASI294 color camera (1h44m and 52 shots of 120seconds)
First time, i was combining 2 different setups in PIxinsight.
