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.
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!
This is a recent edit of data I collected back in January. Image is taken with a Canon 450Da and Canon EF L 70-200mm f/2.8 lens sitting on a Sky-Watcher Star Adventurer. It’s quite a large crop from a 200mm frame. 25 x 3 min guided subs. Stacked in SiriL and processed in Photoshop. Image taken in Northumberland under Bortle 3 skies.

So I'm looking for the best grab and go planetary viewing (and maybe some DSOs) telescope that is relatively cheap (below 500$) that will also support some Astrophotography. I know the SkyMax 127 is a Maksutov and therefore has a high F number, but I'm okay with that because I'll just pop on a 0.5x focal reducer to bring it down to F/6 (still a bit high though.) With said Grab and Go I'm interested in viewing Saturn and Jupiter with high detail. What do you recommend?
Edit: I need one that'll fit into the Sky Watcher EQ5.
Recently got sky watcher skyliner 200P and trying to get started with it. I wanted to use it for terrestrial (sea) views as well. I was expecting the image to be upside down but instead it is angled/sideways. I'm not sure if there is something wrong with scope or I need to tweak anything to get it right? Appreciate any advice. Thanks.
