Scope: Megrez II 80  mm APO  at f/5.8, Location: Laguna Mountains, CA   24 September 2011  Camera: Artemis285

Exposure: 16 x 4 min  (1x1 bin) exposure with UV/IR block, 10 x 4.5 min (2x2 bin) exposure with Ha, 10 x 2 min (2x2 bin) RGB exposures.

Processing: Images were captured  with Artemis Capture (as FITs).  Aligned/stacked and dark subtracted in Astroart with Sigma Combine.   IR / UV Blocking  filter  and Color channels were scaled and  color balanced in Astroart.  Channels were co-registered in Astroart.    Luminance channel consisted of the IR/UV blocking filter exposures blended with the Ha exposures.  Curves and Levels applied in Photoshop to the Luminance channel to optimize star depth.   Final LRGB combine was done in Photoshop.    Final Image size is approximately 1800 x 1350.

North is up in this mirrored image. The star cluster NGC 1027 is located in the constellation of Cassiopeia.  It is just outside an emission nebula complex known as the "Heart Nebula" - a portion of which can be seen on the left side of this image.  NGC 1027 is not physically involved with the emission complex as it is about half the distance away.  NGC 1027 distance to Earth is  about 3,300 light years.   Horizontal FOV is approximately 65'

Image center is approximately - Equatorial 2000: RA: 02h 42m 15s Dec: +6136'46"
