Thanks David, and yes I did use photoshop.

I stacked the different exposures in separate groups and the stacked the groups. I only stretched the longest exposure group. Taken together, this achieved the large dynamic range.

The rest was in photoshop.

- adjust red, green and blue levels of the background to give me a neutral colour balance in the shadows.

- adjust RGB level to further bring out the midtones

- and then a little bit of noise reduction and gentle sharpening

Cheers Peter. I'm glad you liked the frame - some don't for some reason. I started framing my images ages ago as it overcomes the issue of uncertain and often ugly page backgrounds that don't suit every image and often clash.

      I've had a Star Adventure since October, but haven't had a chance to use it until Friday night (work and weather limitations). Also, I don't have a car at the moment, so I'm quite limited to how far I can travel on my e-bike and get to dark skies.
      Ran into a couple of issues, 1. my Nikon Z50 is limited to 30 second exposures and the wifi connection to my phone so I could use qDslrDashboard was terrible (now found out I can tether directly to the phone via USB, yey!). 2. my lens started to fog (a warmer was ordered as soon as I got home and has now arrived).
      Anyway, what I did manage to get was a nice shot of the Orion Nebula.
      Nikon Z50. 50-250mm kit lens @250mm. F6.3. 26x30s exposures. ISO640. Sky Watcher Star Adventure.
      I want to try the Horsehead or Rosette next, not sure how well the unmodded Z50 is with HA though.

      Heres my first ever shot of the Orion Nebula in a Bortal 8 sky (as well as my first nebula). I stacked 52 light frames with Deep Sky Stacker (with dark, bias and flat frames) and then edited the stacked image with photoshop. The Core looks kind of blown out, so I'll need some shorter exposures to combine with this version.
      I've also got a question linked to this: As i'm in a Bortal 8 location (on the edge of London, UK) i feel like i'm kind of limited by the exposure length befor the image just looks completly white/redisch from light pollution. For this photo i used 45 second Exposures but had to bump down the ISO to 200 to make it not look overexposed. In the end, does it really matter if the image looks overexposed due to light pollution because the light from the actuall DSO will still be there and can be filtered out through the power of editing or does this not really work?
      *Any other comments or things i can/should change with the image would be greatly appreciated
      Many Thanks to anyone taking their time to comment!

      First image from my new NEQ6 Pro driven mount, all other images before this were static.
      Sky Watcher 200P prime focus, 10x 60's lights, darks, bias and flats. ISO 200

      Yes I know there is a plane track through it.

      The Orion Nebula imaged in RGB through a Celestron 8" SCT at F10 (2032mm FL) using a full spectrum modded and cooled Canon 40D. Tracked using a Celestron CGEM mount. Total exposure time was 1 hour and 24 minutes.
