Did this Saturday night - never imaged before - It's quite a interesting object - loads going on in it. Shame my FOV only gets the middle. Image details 22X5mins Ha with ZS66 - Atik 16ic. Also attached inverted image showing all the nebula fronts/ star forming regions.
Is it me or can I see CP3O's face in the middle....?
John.

You are funny John, certaininly looks like C3PO!
I like Rosette, there really is a lot going on, enough for a few separate images. Looking good!
Thks Fay - Yep I must try & Mosaic surrounding area....

..... You've got an extra P........!
don't like to get his name wrong! :lol:
cant see c3po, but i can see the scream, in the negative.
One of my favourite targets, looking forward to seeing a mosaic John.
It's interesting to see such close detail, as before this I had thought the dark lines (bottom right) were gaps/cracks in the nebula, but they are clearly darker matter in the foreground, and I never before noticed CP30.

Really nice image John. Lots of detail and nice round stars.
That's an excellent image John. With that quality of data you could possibly enhance the contrast a bit more but it looks really good as it is. Any chance of adding OIII or SI ?

Thks Mac, Carole, Mike & Robert for comments.
It was one of those strange nights - I hadn't imaged in over 3 months yet everything just worked. Put my mount in normal place on grass (three small impression marks still there from last time) & polar alignment was about 1mm off through reticule... Hooked everything up & all cameras worked first time. Did one star alignment to Betelguese & as near as damn it bang in middle of CCD (& FOV on my setup is small..) Used K3 for guiding & worked flawlessly for whole session - in fact I would say just about best guiding I have ever had - I think Max pixel movement over whole of image was less than 2px in either RA or DEC.
I started early because I have limited time to see Rosette from my garden... I was all packed up & back in doors with glass or Red by 9.00pm (after just on 2hrs of subs). I didn't even take darks or flats...
Guess that'll be it for the year now & I'll be plagued with issues.... :-(
Anyway - minimal processing on imaging - just a quick stack & stretch - I hope to get some more frames of surrounding area next time out & try & do mosaic - will process more carefully then..
Cheers for comments - John

I wish we all had it that easy ...
Good to see you back out, even if it was for only 2 hrs. Look at what you could do with with a weekend down at Blacklands. ;)

Cheers Mr. G - Speak to you later in week - John
Quoteyou could possibly enhance the contrast a bit more
Here you go...just a tad otherwise noise & stars size start to increase.....

Really lovely John
John,
Great to see an image from you again! And that one is a great image - excellent detail there and nice round stars.
Mark
Nice, a very subtle improvement.
Thks Mark, Fay, Robert,
Comments appreciated - John
