The Heart Nebula is an emission nebula in the northern constellation of Cassiopeia. This is a narrowband image taken from a scope I share at SRO in California. The second image is the core of the Heart, an open cluster called Melotte 15.
The gear used was a Tak FSQ-106ED on a Paramount ME with a QSI683 camera. Subs were 12x1800s Ha, 17x1800s OIII, 20x1800s SII and a smattering of RGB.
Processed in PixInsight, of course. I used drizzle integration and was very happy with the result. It was upsampled from a native resolution of just over 2 arcsec/pixel to around 1 arcsec/pixel.

Hope you like it. Constructive criticism is always welcome...
