Looks promising, with detail in the nebulosity, and the central star shows up well.

There does seem to be some weird screening effect tough. It looks like a post-processing artefact, so it should be possible to produce a version without it. Have you re-sized the image? What does the version without the annotation look like?

(Adding annotation to images almost always degrades them, especially if jpeg compression is involved.)

[Jim]

Yes, not sure what that is.  I processed the image in K3 and noticed they appeared when I used the unsharp mask.  The original image had the same as the jpeg with comments.  K3 has some parameters to use with the unsharp mask, radius, Threshold and strenght.  Not sure what they are but I'll try and play about with those to see if the artifacts go.

looks good Jim, but that pattern isn't right. I wonder if you're using one of the input filters that interpret the bayer pattern on a colour webcam. That camera is a Toucam with a mono CCD isn't it?

[Jim]

It's an Atik II HS Ian which I think is a webcam with the SC3 mod and a mono chip.  Currently in pieces on my desk as I try to glue the chip back...

[Ian]

I'm not going to ask...

[Ian]

on second thoughts, I will. Jim, why is your camera currently undergoing surgery?

[Jim]

The CCD and board are glued down inside the plastic case (no other support) and had basically come unstuck.  I must have knocked it Sat night and that was the final straw.  Explains why after the first session I could not get any other images out of it!  Bad design really but fixable, just going to epoxy it back in.

Well done Jim, when you have glues the thing back together you can add the RGB

Well done Jim,

A lot would start with the moon or a planet or two, but the chairman jumps into the deep end and pulls off an image like this.
Impressive!!!!

[Jim]

Thanks Tony
I think luck played a very large part.  The acid test is if I can repeat it!  However I am inspired now to have another go.

Jim - that really is very good - well done - when I look back on my first images it's brilliant... I'd be well chuffed. I hope you manage to get the chip fixed so you can have a 2nd try..

Cheers,  John

Well done Jim! I bet you were well satisfied with that.
You are now well on the way. I hope you don't start showing off!!!!!
