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.
My club's Atlas is stuck on the date 11/13/2099. Last night was 6/28/2019. Every time I reset the date and started the 3 star alignment the scope chose Vega and then pointed to the western sky - sorta wonky. When I tried a second star it aimed at a totally wrong part of the sky. I went back to date and it had reset to the11/13/2099 date. The mount has a working GPS module. I went through all the menus and there was no place other than the " sub menu to attempt to replace the errant date. After five tries I gave up. Apparently the GPS was accurate to withing a stride or two. What should I try next? I know my club; they'd rather stuff it in a corner than take the time or money to fix it. So it will be m time and my money. I used the mount several times this year and had no problem.
Hi everyone - it's been a while!
This has been on my hard drive for almost 2 months and I finally got round to processing it...it was quite optimistic of me to try and image this from my Bortle 7-8 back garden, but I gave it a go! While the nebula itself is clear to see, all those gorgeous dust clouds surrounding it were extremely hard for me to capture from my location without a lot more integration time. I think I'll head to dark skies to capture this one next time, along with some more focal length!
LRGB shot with ASI1600MM Pro and WO Z73. 2.9 hours of integration time.
Full details here.
Thanks for looking!
I'm super happy to have found this forum of night sky enthusiasts and look forward to learning and sharing on this site! I am an amateur stargazer fortunate to live in a rural area with great dark skies. I'm used to using a GoTo Celestron.
Unfortunately I'm having a problem with a newly purchased Orion SkyQuest XTg 10.
I've only used it a couple of times. Recently, when I turn on the power, the hand controller (a SynScan V4 GoTo, version 04.39.04) states a message "Both axes...no response!" which means the motors won't work.
I've unplugged all the cords & replugged to no avail. The power comes from a new Orion Dynamo Pro, 12 V, Lithium Power Supply which was recommended.
Does anyone have any ideas what the problem might be?
Thank you 🌟
