This is another finished target for this season.
I (quite) recently bought a TS Photoline 102 ED with FPL53 which performs surprisingly well for a doublet. So I put it to tests and imaging, in parallel with an older FPL51 AstroProfessional 102 ED doublet.
The blue color correction is much better in the newer TS. I shoot luminance often with both and then take the highlights from the better scope.
For this image I also used some older data that I had available, shot with a 130PDS, but that maybe only made my life more difficult. Not that otherwise I shot data through the refractors in a single panel with reducers/correctors, but also in 2 panels with no reducing correctors. Same about the RGB. Some shorter exposures from the backyard, some from a dark site, most of the G data from a dark site, B and R from home (clouds came in at the dark site) and a lot of other adventures.
But in the end I managed to put them all together and made an image out of them.
You can watch it in full resolution and see other details on astrobin: Great Orion Nebula
Clear skies!

Hello, here is my latest image from my remote observatory in Finland. You can see larger version in my blog:
https://www.evenfall.space/post/stellar-nursery
Taken with SkyWatcher Esprit 100mm f/5.5, ZWO ASI1600MM-C, EQ6 guided with ASI224MC as finder-guider, TS Optics LRGB filters.
L: 128x120s, R: 50x120s, G: 45x120s, B: 45x120s. Total integration time is approx. 9 hours.
C&C welcome as always.

I managed to bag another object, this time the reflection Nebula M78 in the constellation Orion.
I was planning to capture natural color subs than add some HAlpha and OIII narrowband data to emphesize the image details and reveal deeper matter, but after processing the OSC/RGB subs, I decided that adding the narrowband data is not necessary.
This image was taken across two nights (juggling clouds), 6th and 11th February, and I managed to capture 3 hours and 18 minutes worth of useful subs (21x60 sec, 19x120 sec, 18x180 and 17 x 300 second subs).
The telescope used was a 80mm refractor, at 500mm FL using my full spectrum modded and cooled 40D DSLR.

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!
