Description

My previous image of the Heart nebula was made in 2014 with a DSLR.

Not enough field of view to include the whole nebula with my TSA102 and my AtikOne6 CCD, so I tried this time to have a nice framing and a good resolution on one of the most interesting area, the Melotte15 cluster.

Only 7h of SHO (5h for the sole Ha channel - 900s subs / 1h for OIII / 1h for SII).
