M 42 with advice from iceinspacers redone.

[batema]

I have had another go at this and this time I did not use my flats(bad) with my luminance data as I remember someone saying for a QHY-9 you sort of need 2 or 3 seconds exposure to avoid shutter issues. Mine were like 0.2 sec. All the rest is the same as previous post except this new processed image.

Advice/comments more than welcome.

You've got great nebulosity out there Mark. Compared to the first though the pink looks a bit cooked. Is there a way you can exclude the stars in the processing, they don't look good after. Overall effect, I think I prefer the first on, bBut at least you know the nebulosity is there and it can be pulled out. :thumbsup:

[batema]

Its all a learning curve Paul. Thank for the suggestions. I'll have a crack at it this weekend. I have finished my marking:)))))))

It sure is Mark, you have that right. :D I'm stillllll plowing through mine. Mid next week puhlease. :prey:

[atalas]

Very nice Mark.

I agree with everything Paulie has said.

Unless you try various things over and over you will never hone your skills...heck I have done the odd repro in my life :whistle:.

That's a very respectable M42.

You have some tilt in your setup. Stars on the right hand side are alongated yet round on the left side.

Stars in the top right are elongating away from the centre of the image which could be coma coming but most likely induced by the tilt. It may be your tilt is uneven with the bottom right not as tilted as the top right?

Does anyone know if these CCD images we take are upside down and left to right of the actual view?? It would help to know that to work out which side of the actual setup is tilting. Perhaps you'll be able to see it just by looking at it.

Greg.

Thanks Greg. I just had the CCD camera with the rectangular chip horizontal with the chords coming from the bottom. I will have a look. I need to read and practice my processing but more so look at maybe utube examples. Could you ore anyone give me a heads up in terms of some resources for this.

thanks

Louie's free tutorials with links posted on this forum.

Ken Crawfords tutorials free on his site although these are more advanced techniques.

DVDs by Adam Block or Tony Hallas are very good. Adam is arguably the top imager on the planet at the moment.

Warren Keller has DVDs as well although I haven't seen those.

Zone system by Ron Wodaski book is good.

Neil Fleming has a few free tutorials on his site.

Steve Cannistra has some on his site for narrowband imaging.

If I were starting again I would get the complete set of Adam Blocks' DVDs and study them all and start using them. They are very complete and he is the best of the best. They cover virtually everything. Ken's tutorials above cover the few things that you could improve on in advanced processing. I like the DVD style of learning processing as you see the same program you will work with. Adam also puts summary sheets at the end of a section with the techniques all written out step by step.

You can also pause the DVD and then practice what you just saw and get used to how it works.

There was only one gradient technique that perhaps there is an error on the DVD. I was able to get it to work occassionally and it would often fail. I then saw someone else using a variant of it and it worked stably everytime so now I use that. It uses the image calculations
menu to subtract the background of a blurred and cleaned copy of an image to subtract the gradients. Apply image menu works better.

I imagine you can print those and form them into a book.

I like! :thumbsup:

[bmitchell82]

Definately honing the image now mate :)

Mike there is a reason why i have called it PS Sidonio Actions.... :P
