IC5146 Cocoon Nebula widefield

[Barry-Wilson]

A labour of love over the last few weeks with generally dismal overcast (and rainy) August skies (as many know).  I have combined Ha and LRGB to give a composite image using PixelMath as well as scripts.  Ideally I'd like to capture more data and longer Ha subs.  We'll see how the weather fares.

This is the first light with my new QSI683wsg-8 ccd along with its integral off-axis guiding, courtesy of that very nice Mr King.  I'm very pleased with the result, but may well revisit over the coming days as I reflect on the image.

Thanks for looking and C&C always welcome.

Excellent Barry, simply excellent.

A very nice image indeed .......

[Barry-Wilson]

Thank you John and Sara.

I was smiling as I processed this late last night, it is such a pretty, almost 'blushing', subject.

Is that a dark nebulae on the center of the image?

Nice photo by the way, lots of things to see [emoji4]

Very nice capture. Thanks for posting.

Very good Barry. I m looking at this on my phone in the sun so hard to see details, but I was wondering how much ha you got? It's a pretty dim signal if I remember correctly

Ahh clouds came, I can see my screen now. Yep you got a good ha background in there.

Thank you fredman, laudropb and Tom.

The dark dusty nebula is one of Barnard's catalogue, B198 and it contrasts the Ha red emissions; seems like the nebula leaving a trail.

Tom - I only captured 7 x 1200s of Ha. The moon's presence is deterring me from capturing more at the moment. I didn't set my sequence to capture 1800s subs as I was still refining my PHD2 settings with the OAG of the QSI: I wish I had now!

I also used PI's large scale structure enhance script to push the Ha background and then blended this result with my no-enhanced HaLRGB. Rick Stevenson has a great PI script which gives you a choice of blending modes, mirroring the PS modes.

Would be nice to have truly dark skies to stretch out the Lum subs too - can't have everything !!

very nice image Barry it made my eyes go funny

Thanks Chris . . . there are a lot of stars in this part of the Milky Way aren't there ?

Amazing depth and FOV, simply wonderful this is image is ( I am a crazy Star Wars fan ).

Well done, Barry. The Ha is very faint in this target. Even with about nine hours in 30 min subs I had to wring it's neck to bring out the contrasts in my version. You have found all the key structures, I think, but I reckon you'd enjoy processing it with more Ha data.

Nice tight stars here. This is always a challenge in such dense starfeilds.

I like that.  Particularly the stars, but also the framing.

there's a lot there Barry - great piece of imaging, definite thumbs up

[Barry-Wilson]

Thanks everyone.

Olly - you have to admire the Baby Q and Astrodon combination for controlling the stars.

Whilst I did carry out some star reduction it was very mild. I had to pause the Ha collection with the full moon, but may visit again next week. The ccd is rotated at 90deg to frame IC5146 so it restricts capturing other targets without re-framing.

Great result, Barry. Most impressive!

Go well!

[Barry-Wilson]

Thanks Jeremy.

That a top image Barry and very nicely processed!!

Very nice widefield. Nice to see the Coccoon in relationship to the dark nebula snaking across the field of view

[xtreemchaos]

thats a lovely image mate,well done.thanks for posting.charl.

[Barry-Wilson]

Thank you Pete, Michael and xtreemchaos.

I do like the widefield framing with Barnard's B168 - I do recall seeing a winderful deep image from Olly some time ago that inspired me!
