NGC 7822 / Sharpless Sh2-171 in Cepheus

[x6gas]

We've had a couple of clear nights over the past week here in Oxfordshire and I've spent the time getting some data on Sh2-171 in Cepheus.

I've had real trouble with this.  After a[nother] strip down and rebuild of my mount, my guiding has got worse - still working on that - so I've been strict and tossed have the subs.  And then the processing.  Seems a tough target because there is Ha right across the frame but I've found the [OIII] and [sII] to be really faint.

I've tried this in the HST palette but it doesn't really do it for me - the Ha in the background is responsible for the 'orrible brown everywhere.  Ditto the CHFT (which I'm not even bothering to post) and I think I prefer the bicolour version.

Scope: Takahashi FSQ85EDX

Mount: CGEM DX

Camera: Atik 490ex

Guiding: Atik OAG; PHD; IMG0H

Data: Ha - 11 x 1200s; [OIII] - 11 x 1200s [sII] - 9 x 1200s

They are great Ian - not one I've come across. My preference is for the first two and I actually like all that brown.

Beauty is in the eye and all that so I must say the Hubble is looking like it's nicely on it's way. The yellow / brown is a function of so much Ha and you'll have to keep playing with colours until you do like it.

The blue is just about right for me,

Dave.

The Hubble palette rendition is my personal favourite.  Well done and keep it up

[Gina]

I agree with others - the Hubble version is very nice indeed - I like it and think you've done well   Of course, the Hubble palette is not to everyone's taste and it took me a while to like it but now I'm a keen advocate - I like bright colours and I feel it can bring out data that isn't otherwise seen.

Ian, you are being a little hard on yourself - the outcome here is very good, especially the Hubble palette version. Hope you get the mount sorted out soon.

That's a great shot the middle one being my favourite

[Ewan]

I think thats a splendid shot Ian & worth all that effort, i know what you mean about the brown colouring but you could probably give it a tweak to calm it down.

[x6gas]

Thanks for the very nice comments everyone.  I've really struggled with this target for various reasons and was a bit downbeat but as usual SGL comes to the rescue!  I really appreciate the encouragement.

Posting the Hubble version brings out a nasty pink gradient for me in the top right corner so I've reprocessed to see if I can lose that.  Here we go:

I love the brown colours, very unusual & moody (like Per's recent images).  I plan to try NB images when the clouds clear and your efforts will spur me on.

Very nice dude

Thanks Barry.

Yes, do give NB a try.  This was imaged under less than ideal skies and with a moon 70%+ lit.  You just can't do broadband under those consitions.

Cheers, Ian
