I wondered if I could do a little better with the data that we got from our trip to Les Granges in November.  Our last effort got to this: https://stargazerslounge.com/topic/280758-ngc-7023-iris-nebula-from-les-granges/?do=findComment&comment=3075021

I went back to the un-stretched data and reworked it.  The aim was to try to bring out more of the faint stuff without blowing out the stars.  This version seems to have a bit more sparkle and so I hope you will forgive me for reposting it.  As before it is:

18 x 900s each of RGB 
21 x 1900s of Lum

Shot through Olly's Tec 140

Thanks Graeme and Olly.

.... You really do have to pull in the Praying Ghost at some point!

It might look rather sweet imaged through that 14" behemoth that you are planning....

I don't think the behemoth will see service as a deep sky imaging instrument. I reckon it will be best employed as a visual scope and, perhaps, as a planetary imager for those so inclined. The TEC has done well on the Ghost in the past, though.

      The 6th January was clear and still and so at last a good night for imaging (not perfect as Moon was still waning).
      My 8" SW 200P Reflector was wanting to be used and so it was carefully mounted onto the HEQ5 and payload maxed out with the imaging train.
      Yeah I know - this combination is a big ask for the job (but an EQ6 is beyond me at the moment!). Anyway with careful balancing and hardly any wind it was worth trying!
      Nebula were best targets and again new ones for me.
      These were the Bubble Nebula, Cave Nebula and Monkey Head Nebula. The Optolong L-eNhance Dual Narrowband Filter was used for all images.
      Usual calibration frames and dithered instead of Dark's. Other 'Astro Stuff' is in my signature. 
      Any constructive criticism's welcome.

      Images:
      Bubble Nebula (Sharpless 162) 15x240secs (1 hour of data).
      Cave Nebula (Sh2-155) 7x240secs & 23x300secs (2hrs 23 mins).
      Monkey Head Nebula (NGC 2174) 44x240secs (just under 3hrs).

      This is a close up of IC 2944, also known as the Running Chicken Nebula or the λ Centauri Nebula, with the Bok Globules visible in the upper third of the frame. IC2944 is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. This image was exposed using a Cooled and full spectrum astro modded DSLR through a 8" SCT at it's native 2032mm (f10) focal length. The total exposure time was 8 hours and 25 minutes, through a UV/IR filter to capture natural colour data.

      NGC 6357 is a nebula about 5500 light years away in the constellation Scorpius near the better known NGC 6334, AKA the "Cat's Paw" or "Bear Paw" nebula. This nebula was also given the name War and Peace Nebula because of its appearance in infrared images, the bright western part resembles a dove and the eastern part looks like a skull. This photo was taken through a 8" SCT at f6.3 (1280mm focal length) and exposed using a full spectrum modded and cooled Canon 40D DSLR.

Total exposure time through the SII, HAlpha and OIII filters was 40 hours.
