Very nice subject Alan. I just get the feel the outer parts of the nebula seem a little soft and mottled looking.
Sorry Alan just something looks wrong.

Nice image Alan, I can see what Doug is talking about too. The centre is very crisp, but the outer regions soft. All the best.

Sorry Al but

NGC 2244 (http://en.wikipedia.org/wiki/NGC_2244) – The open cluster within the nebula (Discovered by John Flamsteed (http://en.wikipedia.org/wiki/John_Flamsteed) in 1690)

not the designation of the nebula

Not bad by the way

Thanks Trevor thats sort of what i meant to say

Hey Al just get rid of the green background and it will look pretty good mate :thumbsup:, nice work.

The Rosette is a must do for me this season, I have only ever done a pretty basic B&W Ha version (http://www.pbase.com/strongmanmike2002/image/69299821/original)and with just a 200mm lens to date way back in 2006 :sadeyes:

A little too green, dynamic range looks flat..stars saturated to white and a tad bloated.

Guiding spot on. I like the framing.

Stick with it :)

Appears better without the green. Had a quick fiddle - hope you don't mind.

Thanks Allan,Peter yes ill have to work on the dynamic range and fix the stars as well as the colour
hey MIKE needs a bit more FOV dont now anyone with C11 AND hyperstar by chance

Hi Alan,

I'm sure the data is there but the processing seems to be letting you down in making this a cracker image. IMHO the background should be black - the emptiness of deep space - and the Rosette - rose red. Do a google search and look at other renditions as a guide.

Did a sidonio and took on some advice i think this looks a bit better,always room for more inprovement

Very nice Rosette. You've got some pretty neat details in there. I'm still to get one that sharp. Well done. :thumbsup:

Nice work, lots of detail there. Plenty of data. I had a fiddle with the latest pic, what do you think?

That latest repro is very nice Alan! A beautiful rose - you got some excellent data there with heaps of detail. There's still a tiny bit of green in the background levels though (Scott got rid of that).

Maybe just a matter of calibrating your screen? I got a dual monitor setup (identical monitors, but calibrated and connected differently) that has really helped me finding color problems. What looks black on the one can look distinctly red/green/blue on the other!

With the colour balance addressed Alan, you've come up with an impressive image. Enjoyed it.

Thanks IVO and Jase you right there i have 2 monitors myself and they need colour calibration both are differnt my next job.

Alan nice work indeed, but to my liking it is to tightly framed, i prefer the wide field look, but that is IMHO only, well done.

Hi i have added more data to this image now 6hrs worth i think it has brought out more structure in the nebula anyway thanks for looking

There is some nice structure in the nebula but I think the red is too deep. I could be wrong as I am only on my training wheels in processing but it looks like there is an issue with the red channel in this image. On the PS histogram the curve it looks completely different from the green and blue channels. I believe they should look similar.

Hi Alan,

I can't wait for the clouds to clear here on the sunshine coast. It is a beautiful Rosette and you should be very proud of it. I can not believe school has finished and I have holidays abound and nothing but terrible weather. I need more astrofests.
