Well Mick, that is not looking shabby!

Can you get it bigger?

That's very good Mick, glad you managed to sort out your problems.

Looks good to me Mick. I think you have captured as remarkable amount of nebulosity despite your Canon being unmodded. Great stuff. Now you just need to make sure everything is reliable.

BTW I usually post on here at 1024x768ish. Could we have a link to a larger version?

Original post amended with link to bigger image (complete with bigger warts  :-?)

Camera is modded and also still misbehaving

I'll be testing everything during the week and hopefully get things working right

It looks like a night on your own was what you needed. Very nice image

Mick - looks superb to me - certainly your best image yet - really impressed that you have captured so much of the background stuff - well done with all your perserverence especially considering all those software issues you keep having.

Great,  John

Very nice Mick - especially the big one.  You've also captured a lot of faint stuff there in the background.

Overall I think the image looks a bit too red but that's just a minor criticism.

Your focus and collimation looks fine to me - only the stars toward the corners look elongated.  Are you using a flattener?

Well done for overcoming all the technical difficulties to achieve this.

Thanks all, despite all my moaning I am quite pleased with this but know I can do better.

I agree with the red and tried to reduce it but started losing a bit of the background.  I'll reprocess again some time and press some different buttons in PS  ;)

Haven't got a flattener and forgot to take up John's offer (different thread) - On my list of things to get though  :)

Looking very good Mick though you definitely need a flattener.  I'd consider taking up John's kind offer to get rid of that 'Warp' effect.

Reprocessed without the gentle touch to bring out the warts - got a bit greedy for nebulosity  :oops:
