Another one I imaged earlier and have just got round to processing.

6x 75 secs @ 1600 ISO. Canon 350D at prime focus on TAL125R 5 ins frac @ F9. Processed ImagesPlus & PS.

you've done well with that one MD. It's a dim target and not easy working at F9. 75 secs is pretty good going as well at that focal length. There seem to be some sharpening artefacts so just wondering if you have pushed that a bit too far.

[moondog]

Thanks Martin.

Yes, I guess I must have pushed it a bit too far with the sharpening. I'm a novice imager and still have a lot to learn !

I'll see what I can do to improve the image.

Just ease of a little on the sharpening MD and leave a little fuzzy. I think it will then be a super M1 image.

[CELESCOPE]

well you got it MD . as Martin says not an easy one, but the colour looks nice , and yes just pushed a bit to hard on that , but thats the challenge now to improve , well done on a good start

Thanks for the useful comments, Martin & Rog.

Here's a 'backed-off' M1 !

Do you think this is any better ?

Yup MD - like that one alot. S'a beauty! 8)

Yes MD it's definitely better and there's some of the crabby features showing up. If you managed to pull that out I bet you have some of the fuzzy nebulosity as well. The sky is very black and my guess is that the image is a bit clipped at the black end. I think you have probably reduced some sky noise by moving the black point slider in levels over to the right or maybe you have used the black point dropper tool. This might have lost you some fine detail. Maybe better to leave things a bit noisier and show a bit more nebulosity.

Could you post an unprocessed stacked image?

Looking good to me MD! However I am the untrained eye!

Martin, as requested I attach the original stacked image of M1 - including the vignetting and the amp glow !

This is a JPEG of the original FITS file.
