M42 Color Again - AT66ed

Posted By Jason Boyce

That looks great Joe!
It has a bit of a narrowband look to it,I like it grin

Is the blue bloat from the scope or a focus issue?
I have been having a hard time with the focus on my blue filter and getting some halos sad

Image Processing Questions

Posted By Jason Boyce

Hi Louis,
I have never used the Fits plug in so I'm not sure what the proper steps would be with it.
Some things that strike me as being out of order with your processing are you did not mention doing any dark subtraction,are you doing this?
This is the first thing I do after looking over all my subs to make sure they are acceptable.

Second thing is stretching all the individual subs before combining them.I think if you align and stack before stretching you should get a smoother result and save yourself a lot of work too!

My workflow goes something like this most of the time.
Open all subs and make sure they are usable.
Do a dark subtraction and flats if you have them on all the subs.
Do a hot and cold pixel removal on all the subs(I sometimes skip this,it takes awhile)
Align all the subs, LRGB if that is what you have.
Stack the aligned and calibrated subs into seperate LRGB stacks.
I don't have a fits plug in so I then convert the stacked LRGB subs into Tiffs for use in Photoshop.
I combine my RGB channels in Photoshop using the merge channels function.
Sometimes I do a DDP stretch on the luminance before converting it to a Tiff.

Now I have my master luminance and RGB stacks,from here I fumble around in photoshop with it's plethora of tools until I get something that looks OK smile

I am not very experienced and have an awful lot to learn so I may very well be doing something I shouldn't or not doing something I should.

Hope this helps,
Jason
