Looks like a big wave? This thing is a lot bigger than what the initial sub exposure appeared, but then I didn't do a quick DDP or anything to check. I've been increasing by a few subs each morning (began trying 8/30) but keeps overcasting and cutting my session off. So I decided to post what I have so far in case we greydome.

Nothing fancy in the processing here. I used >unsharp masking and some very lite sharpening and some contrast adjusting< in sequence group iterations after putting the color panes together (and stretching) to enhance the dynamic contrast of the 'surface'. Applied noise removal in two of the passes and added a slight blur at the end. MaxImDL and PSP7photoX2

12:10:8 Ha5nm:SII3nm:OIII3nm - 20 minute sub exposures.

I would absolutely say that is your best one yet (IMO). I freaking love it.

Thanks you two! And to think I was telling myself it wouldn't be that difficult until stretching revealed so much more to it... then panic about why the OIII not showing in the 'bowl' - 'oh no, not another mosaic!'

Thanks Terry and Richard - starting out clear again tonight. I need to figure out what happened with my OIII channel, comparing to other NB images it seems like it on 'the wrong side'?!

That's beautiful Jim! I see your OIII, you picked it up on the end I cut off in my image and you can just see it in the inside curve of the nebula. Terrific image!

Warren thanks so much! I dedicate this image to you (and hope it's worthy by the time i complete it?!)- as I was so impressed by yours that I decided this year I'd give it a try if weather allowed. You never know who you inspire ;) ! Am uncertain but I believe there are some globs or beads in this object I've not heard folks mention or call attention to... do you see anything like that in your image at native resolution? I know this isn't a great crop of them but shows the area at my native screen resolution.

Great image JIM. Only remark I could give is that you need a bigger chip :) Maybe try a mosaic? ;)

Thank you Wouter - it was either the 16803 chip or the RH200 - I decided to go with the new scope. I very well may try another mosaic with this if our skies allow.

Tough choice indeed.. I've seen the OS RH200 at the CEDIC in Austria earlier this year. It's really a cute telescope. For me it was either that one or the PM-MX.. You know where I went.. :D

Wouter, no question I do have 'mount envy' there!

Wem and Madratter - thanks for the comments, I have high hopes for this one, my hope is for enough clear sky time to get 18 exposures per filter or more if possible. it makes a huge difference in the fainter stuff... i had to do a little fudging (intentional blurring and excessive Gaussian NR) to make this image not horrible there though you can still see the grain.

thanks nodalpoint - appreciate the comment.

I like coming up with my own names for objects based on NB (and sometimes 'the other imaging')imagery, this one should be called 'the golden fleece'.

Yes, I see the same thing in my image and they almost resemble star forming areas surrounded in dust. I hope you get the chance to build your mosaic as I think this will turn into an awesome image. I like the palette you have come up with for this, it is really striking!

Warren - that is interesting and thanks for taking a look! I love finding little things like these in our amature images, it's pretty amazing when you think about it. :fingerscrossed: about our weather holding up for another mosaic. Were getting a late heat blast here - I read in the papers it's very broad in scope even out to ILL and OH ? this evening cannot even reach -10 on the ST without exceeding an 80% duty cycle...

Cools off into the 60's in the morning so getting to -15C for this object not too much a reach.

Yes, hotter than :flame: here but supposed to cool off dramatically on Friday and clear up. I may be doing some NB myself this weekend!
