  1. The Needle in RGB A beautiful edge on spiral galaxy in the constellation Coma Berenices, around 38,5 million LY from earth. Investigations with the Spitzer IR telescope suggests that the galaxy may actually be a barred spiral galaxy with an inner ring as well. -------- Finally got around to processing my data on NGC 4565 from March. This was one of my "test projects" from this year, where I only shot R-G-B and created a synthetic luminance master from those frames. I think that the most efficient way is still to shoot pure luminance and then just enough R-G-B to get the color you want. Unless one is imaging star clusters, then I think it is totally fine to skip luminance altogether and get as much color data as possible. I will try to do a "super luminance" where I add the R-G-B frames to the luminance stack at some point as well. Shot with my Hypercam 183m V2 and totalling aroung 4,2 hours of data. More info here: https://www.astrobin.com/412663/B/ Comments and critique is always welcome. I decided to put this post in "Getting started with imaging" as it may be interresting for beginners thinking if luminance is worth it.
