Title: Vdb 126 in Vulpecula
Post by: MarkS on Aug 01, 2014, 22:24:41
An unusual object this time:  vdb 126 in Vulpecula
A packed area of the Milky Way with a distinct dark lane and a small amount of reflection nebulosity.

Modified Canon 350D on Tak Epsilon 180ED with IDAS P2 light pollution filter. 6 hours of 5 minute subs at ISO 800.  Taken on Wed and Thurs nights 30 & 31 July.

Nice Mark - Guessing that was a tough one to process - John

Makes a nice change Mark.

Yes, it was tough to process and I'm not certain I've made the best of it.  It ideally needs a few more hours of data.

Really nice Mark. Unusual subject.

That's lovely Mark, only the large version does it justice though.  Yes a tough process but then it was well worth the effort !

I now have over 15 hours of data for this.  Time for a re-process!

So here is the final result - 13 hours of total integration time.

The extra exposures gave me the headroom to get the final image as I wanted it - with better colour balance and more subtle variations in the dark lanes.  

See what you think:

Looking good,

I do see hints of the loch ness monster though,
Head top right of the dust lane, going down the neck to the body.

Funnily enough Olly Penrice has posted the same image this week on other forums and he describes it as a running brontosaurus.  Never seen this object before and then twice in one week.

Interesting - I'll look out for it. Come to think of it, it does slightly resemble a Brontosaurus!

The other way round its a dog chasing stars.

Version 3 brightens up the whole image, improves the colour balance and removes a residual blue gradient along the bottom edge.

Looks great Mark, but better watch out for the "not allowed to improve your image and reprocess it" brigade.

Personally I don't know why they think it's a problem and shows new imagers how the same image can be improved which helps them learn.

That's really excellent Mark, one of your best images if you ask me.  There's barely a space that isn't dust or stars !

It's certainly better seeing the image evolving in one thread, much more easy to follow.

Thanks for your comments.  I'm pretty happy with the final result.  From an artistic point of view it's just a shame there isn't a bit more reflection nebulosity but the the Universe is to blame for that!
