Another Xmas cracker Olly..  I have a feeling that something rather spectacular is being cooked 

Dave

Excellent image Olly..   the ASI2600mc has a UV/IR cut window..

Merry Christmas

I love the first one, especially in its rendition of the dust (and I agree with  tooth_dr about the refreshingly different framing. In the second one I feel the colour has gone out of kilter, especially the Flame which has lost its unusual orange-yellow.

Olly

Thanks Olly...   on reflection you're right   ... here it is with I believe better colour (blended in from the wide field image).   interestingly the wide field colour was from a colour camera (ASI2600mc) rather than the mono I did through the E150..  I wonder if the lack of colour in the Flame is due to the large spectral gap between my red and green filters?

Dave

Whilst the Esprit100 and GT71 were busy capturing the wide field view the Esprit150ASI294 was focussed on the Horsehead and Flame...  here's the result of that data combined with data from 2019 and 2021 taken through the Esprit150 with an SX46... in total it adds up to 5 hrs per channel RGB plus 14 hours luminance over the Horsehead and rather less at the edges as this is a mosaic. Processed in Pixinsight and Photoshop..  with BXT and SXT used to control the stars.  No Ha in this one.

Thanks again for looking

Wonderful image and a nicely different FOV.

Amazing Dave. Great stars!

I love these bits:

Stunning detail - so much better than the usual big blue blob - like what I have achieved

Love the billowy brown clouds of dust against the red reflection nebula. Great capture.

Wonderful image Dave, I really like the surrounding dust and the colour of the Flame Nebula.👍

Thank you all much appreciated

Dave

Old favourites the Horsehead (Barnard 33/ IC434) and Flame Nebula (NGC2024)  in Orion... also included are Alnitak (left side of the Belt) and reflection nebula NGC2023, IC431, IC432 and IC435.  7hours of  Luminance through Esprit100QHY600M and 7 hours RGB through GT71ASI2600mc captured on 14/15 and 18/19 November plus 5 hours Ha through GT71ASI1600mm captured in 2021. Processed in Pixinsight and Photoshop.

Thanks for looking

Dave

Hi Adam.. I had a look too and got a similar sharpened result to Kon..  as he says seeing has been poor recently ..   I'd suggest upping gain to get 10ms and aim for 70% on the histogram ..  and see what you get 

Dave

Its moved Adam..  is this what you want?

Oh wow both are sublime but the wide field is spectacular.

Kudos for taking the time and effort in getting so much data,

Thank you Steve

The wide field is simply stunning, the dark nebula against the rich Ha is absolutely captivating 

 

Thank you

Fabulous! Exceptionally deep and yet exceptionally clean with superb levels of local contrast in the Ha. Beautiful processing, too. The result has rewarded your effort.

Olly

Thanks Olly..

I fully agree with stunning, spectacular and fabulous! Probably the deepest cocoon images I have seen.

Spectacular! 
Great work with the array of different scope and camera combinations. 👍🏼

Thanks Steve...   I've had to bolt a Skywatcher Counterweight onto the end of the shaft there's so much on the mount... still guides at 0.3" RMS through the ST80 though!

Quite stunning.  Worth all the collection of data and effort combining.

Thanks Carole... 

IC 5146, the Cocoon Nebula, is a reflection/emission nebula in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars enveloped in a bright and dark nebula. The cluster is about 4,000 light years away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.

The dark nebula Barnard 168 is a dust lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

Source Wikipedia.

Data gathering for this project started at @ollypenrice's Les Granges in August 2019 when we imaged the Cocoon using Olly's Mesu mounted twin TEC140,s with Atik460 and Moravian8300 cameras...  a year later I used my Esprit100SX46 to gather an hour each per channel of LRGB and my GT71ASI1600 to gather 4 hours of Ha... combing all this together produced a very nice "Cocoon core" and started to show the dust lane B168 and the background Ha...  A few images I had seen on Astrobin (most notably this one by Kevin Morefield The Cocoon | Exploring the Dust and Ha Emission Surrounding an Old Favorite ( Kevin Morefield ) - AstroBin ) inspired me to add more data and see what I could produce.   Three clear moon free nights in late October allowed me get some more through the rather complicated set up I currently have...  on the Mesu an Esprit150SX46, on which is piggybacked an Esprit100QHY600mm then a GT71ASI2600 and an Askar200ASI294mm either side of the Esprit150.. all guided by an ST80_ASI174 at 0.3" RMS...   In total I ended up with 14 hours of Lum, 13 hours of Ha and 11 hours of RGB.   Processed in Pixinsight and Photoshop with assistance from the Normalise Scale Gradient script (used to combine the Integration files from all the different sources) and Russ Croman's Blur, Star and Noise Exterminators.

It was the first time I had used the QHY on the Esprit 100 and I had back focus issues on the first two nights caused by an adapter not threading all the way down and then by increasing rather than decreasing the back focus..  grrrr..  this meant that only the central 70% of the frame could be used.

Anyway here it is, actually two versions a crop at 1.42/pp (the native resolution of the Esprit10)  and a wider field  view.

Thanks for looking

Dave

That's a cracking image Ivor! Well done

Dave

Very nice..    Having recently discovered and been impressed by the Foraxx palette script for narrowband in PI  I'd suggest you run your data through it, it'll produce an SHO type image from either SHO or just HO data.

Well deserved!

Excellent image Adam...

You can find the filter wheel driver in the SX website  in the section Support … Resources… Software Download ..

Very nice Adam..  8 minutes ..  I must time myself next time .. I do know that I can do it without the wife even noticing I’ve left the room 

Dave 

Fabulous image Olly... 57 panlels and all data collected in just over a month, makes us here in the UK just a trifle jealous!

This is Sh2-132 at an unusual angle

Indeed it is… who’d have thought you’d find all that inside a Lion 

Dave

Very nice Rodd..   does it have a catalogue number? 
 

Dave

Yes Dave, It has a slight recess where the front plate sits on the body so by turning it over you create some extra room for the filters.. for my efw (8x1.25) the amount by which it is too shallow the right way around is tiny and some of the filters are ok … but some rub 

Dave

Hi Dave ..   I have Astrodon 1.25 filters in a ZWO EFW..  i needed to turn the front plate over to get the required clearance ..  works fine 

Dave 

Very nice Olly..  with my Samyang setup I’ve found that stars look best without BXT, removed after a light stretch, PS colour enhanced using Noel’s action, blurred, then slightly sharpened with UnSharpMask..   if needed remove blue halos with Noels action and red halos by inverting and running HLVG (or scnr) then added as multiple Screen layers to taste…. the stars get more stretched the more screen layers you add..  and you can just erase brighter stars from one or more screen layers to reduce them ..  

ps I always take them stars out in Pixinsight after the light stretch with ‘unscreen’ ticked in SXT

Yes, outstanding Dave! So many great objects compete for attention in that image.

PS. Like before I do wonder what even more star suppression would make of it😉

Thanks Goran...   Be my guest and see
