Hi all in IIS again,
We are all happy I think to see some great clear weather over the weekend.....:clap:...been a while up here..
Managed to image a few objects on friday and saturday night and early sunday morning...
Here is a shot of M42 done with the genesis. Consists of 10x4min,5x1min,5x30sec. DF removed and stacked in registax and processed and masked in PS. No unsharp masking done.
Quiet happy with the final image..
This pic is about 500k in size and cropped by 30%..

Nice work Gary

This is a rather striking image.

I agree the guiding looks really good with nice point like stars! You have preserved the detail in the bright areas well, the colour balance is nice and considering the rather short exposure time, you are even starting to reveal some of the extensive surrounding faint background nebulosity :thumbsup:

I notice there are some clean darker circles around some of the stars though, particularly noticable in the stars on top of the nebulosity, did you have to reduce one of the colour frames to match star image sizes?

Something in your processing is also giving this image a slight paint by numbers look to me, ie there are borders between brightness gradients as if it was screenprinted (do you know what I mean?). It is quite subtle but is giving the image an ever so slightly unatural look. It is most likely to be the artificial noise reduction or smoothing you have used or perhaps some filter used in the processing? any ideas?

Still, a very nice image regardless :thumbsup:

black is black and white is white
focus spot on, good tracking
fine detail nice colors core nicely revealed
i like !
maybe what Mike is referring to is the contrast adjustment? to my newbie eyes looks good
cant wait to try this out with my 80mm myself!

Thanks Mike, Jase, Petra and Frank for the comments,......:thumbsup:

Mike, the slightly darker circles around the brighter stars are left after removing CA with Noels actions to remove small blue/violet halos..(thats why I got them).I shall invest in a lumicon anti-fringing filter to fix this, but they do a pretty good job of removing them.
Didn`t use any noise reduction at all. As for the color gradients, the original 16bit tiff image doesn`t look quiet as obvious as the jpg but I know what you mean, don`t know why yet as I only used whats in PS and a action or two? shall work on that??
Thanks for the comments as it all helps me with my processing and I have come a long way over the year!!!!
Cheers Gary
