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.

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.
I have a question about filterwheels; SBIG filter wheels specifically. As far as I know they are the only ones that really use the 8 position filter wheels. So I have it loaded with L, R, G, B, Ha, OIII, and SII. So that is seven filters, what goes in the 8th slot???
Thank you for your insight,
Not many chances of Solar Imaging this year so far but caught this one.
