tried for NGC 1528 (Halifax)

BGO shot NGC 1528 for me. An open cluster in Perseus. Just for fun.

Whoa. Something went wrong with the luminance data gathering... (The red, green, and blue channels are OK though.)

open cluster NGC 1528 luminance with registration problems

Luminance only, 30 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

I had tried to view this big cluster on the evening of 26 Aug '16 but was clouded out just after slewing.

aka Collinder 47, Melotte 23, and OCL 397. This is considered by many an interesting and fun target. The Astronomical League has it on their deep sky binocular list. It is listed in the TAC eye candy table. It is also a Herschel 400 item.

Given the RGB data is OK, I may try to assemble...
