Here is a telephoto version of these classics that are still visible at my latitude for a few hours. I gathered the Ha data 2 April with my Canon 300mm f/4 and a 12nm clip filter (unmodded Canon 60D, 6 x 25 min) to which I added RGB data from 11 November gathered with my Samyang 135mm f/2 (169 x 1 min). All @ ISO1600. So totally 5.3 hours of data.
I think I like the colours but some may think they are a bit over the top. Maybe I should pull back on saturation?
C & S most welcome!
Here is my version of the Pelican Nebula.
Data capture done during several nights from the 14th august to 22nd September 2017. Location, country side one hours drive south of Copenhagen.
HA 5nm: 47 x 600 second subs, moon lit nights.
OIII 3nm: 29 x 600 second subs, no moon. SQM 21.10
SII 3nm: 37 x 600 second subs, no moon SQM 21.30
Total exposure: 18 hours 50 minutes
Calibrated and stacked followed by deconvolve and DPP in Maxim.
Layered as Hubble palette and final curves in Photoshop. Reduction of magenta saturation and lightnes to adjust star color in the flattened image.
Equipment: Mesu200 mount. 10" Skywatcher Quattro, Atik 460m camera and Astrodon filters. Offaxis guided.

Thanks for watching.
It was such a warm night last night that the camera didn't get below -26c
Made it really pleasant to get the scope up and running though :-)
Here's my start on the Pelican Nebula in narrow band - the weather doesn't look promising for the coming week and before you know it it will be passed its prime location in the sky
This was 11 x 5min Ha with flats but no darks (I HAVE to get around to making a dark library lol)

I have just acquired a new (used) telescope (many thanks PhotoGav), A Skywatcher Evostar 80ED DS-Pro and I have decided to step up my image processing a notch and have had my first try with PixInsight 1.8.
7+ hours of data over 4 nights with good conditions and a lot of learning have resulted what I would call my first WOW! image. Feeling very proud of this one. Done in narrowband using the Hubble Space Telescope Palette (SII= Red, Hα = Green, OIII = Blue)
