SH2-155 Colourful Cave Nebula

[Avdhoeven]

Lately I have been working a lot with Astropixelprocessor. With this software I have been starting to redo some of my data to see if I could catch more details. I'm astonished about the performance of this program to be honest. The stacked results showed smaller stars, more details and less noise.

This image shows SH2-155 aka the Cave nebula which consists of 215 images! With APP I was able to integrate my Luminance, H-alpha and UHC data to get really the most out of the data. 

I'm very happy with the result that came out. The colours of the stars were as I liked them to be and somehow it resulted (in my opinion) in a very colourful representation of this beautiful region in the sky. 

Exposure info:

Telescope: TMB92
Camera: QSI583ws

Lum: 96x300s + 15x600s
Ha: 42x1200s
UHC: 35x600s
R,G,B: 9,9,9x600s

Total: 34,8 hours

So beautiful, lovely colours

Heard a lot about APP being used lately, maybe I need to give the trial a go?

I couldn't agree more

Another admirer here. Great image.

That’s stunning!

When you say APP integrated your Luminance, H-alpha and UHC data, do you mean you processed it together?

First I tried processing them all at once, but my computer couldn't handle that. Than I processed the 3 stacks and then had APP integrate these 3 stacks together. That really worked perfectly and gave much more detail. Especially in this region where the H-a and Lum are really showing different parts...

Thanks for explaining this

Just  to give an idea here you can see the Lum and H-alpha images together. You can clearly see how different the details are shown in both images... That was one of the challenges to get all details in one image...

Lovely image and definitely +1 for APP, it does the integration and channel combination really well.
