Three darks and one no so bright - NGC7129, NGC6882, Barnards and Saturn

[Roberto]

Hello All

Some of these completed (remotely) whilst away on holidays in August, some more recent.

NGC 7129, NGC 7142 and some SNR G107.0+9.0 - LHaRGB

Details here: https://www.astrobin.com/qyktqt/I/

I had done this area in 2020 but the addition of Ha and the wider FoV of the camera help.  Taken with the usual tandem refractor setup.

Dates:  5 Aug 2024, 9 - 13 Aug 2024, 16 Aug 2024

NGC6882, NGC6885, Caldwell 37 in Vulpecula - LRGB

A nice cluster within a cluster in Vulpecula.  Details here: https://www.astrobin.com/61t3mo/D/

Dates: 30 - 31 Jul 2024, 2 Aug 2024, 4 - 5 Aug 2024
Frames: OSC - 143×150″(5h 57′ 30″)
IDAS LPS-P2 50 mm: 78×300″(6h 30′)
Integration: 12h 27′ 30″



Tokyo 994 - including Barnard 8, 11, 12, 13 - LRGB

This I finished over the weekend but it's too dark.  I may need to reprocess.  It's a string of dark nebulae (several LDN and Barnard objects), collectively called Tokyo 994.  Details here: https://www.astrobin.com/9mv9yf/D/

Dates: 17 Aug 2024, 11 - 14 Sep 2024
Frames: OSC - 142×300″(11h 50′)
IDAS LPS-P2 50 mm: 72×600″(12h)
Integration: 23h 50′



Saturn - 22:34 UT - 14 September 2024

And a quickie of Saturn on Saturday night.   Still very low for imaging from the UK but looks nice visually.  Can't wait for next year.  This one taken with the 10" f/20 Maksutov.

Fantastic results Roberto.  Love Saturn and in particular the first one.  I have done NGC 7129 at DSC and even at Bortle 4 but never got a good result.  Just shows what long integration does. 
Not heard of the otehr two before.

[Roberto]

Thank you Carole.  I have taken new flats for my L filter and re-processed the L image and LRGB.  Both attached below.

Reworked L



Reworked LRGB

[Carole]

I like the re-worked L but not so much the re-worked LRGB, looks a ittle blotchy. 

[Roberto]

Indeed Carole.  The RGB image alone is better than the LRGB one.  I will leave it at that for now.
Thanks

I've reprocessed the LRGB once more.  Now from scratch, starting with the RGB and adding the new L, instead of adding the new L to the old LRGB...I think this is it.  Won't do more to that data.

Think the final version looks a good improvement Roberto.
