I have been working on a vela snr shot but last night I decided on doing a quick eta. It has come out surprisingly good probably because of its brightness. This is 1 hour of ha and 30 minutes of s2 and o3. The Tiff on my computer is amazingly sharp and uploaded images don't do it justice. I have gone for a more subtle "natural" Hubble palate I will probably do a more traditional one later today.
Great result Peter, you might try to bring back a little detail in the blue regions near the keyhole? I think your processing may have smoothed it out a bit there? Still, it looks beautiful

I actually processed this in 10 minutes before I went to work this morning. Probably not recommended for getting the most out of your images ! I have been reading how different people process their images to better my skillset. Thankyou for the constructive criticism!
That's really nice Peter, love the sharpness
I keep wondering, is it the mirror or the rigidity of your cf tube or both
How long were your subs
Do you have a similar one with your 8inch f4? Would love to see comparison of both ota's

The subs are 10 minutes long, I do have a shot from my 8 inch but it was one of the first shots I ever did. Thus comparison is not great. The one thing I can say about rigidity is that my guider is one of orions finder guiders. It is attached to the tube with a regular finder bracket and is held in place with an O ring and 3 screws. With my 8 inch guiding was impossible until I switched to an OAG, with my carbon tube it just works. I have improved my polar alignments and kitted out my mount with a belt drive since the new scope too so I cant say that it is all the carbon tube, but it may have played a role.
I captured a few more subs last night and processed my hat off. I am still new to narrowband imaging, and getting colours the way I like them and into a good luminance layer are still giving me trouble. This will have to do for now. The second night was very still and I had subs coming down with FWHM values of 3.4, being that I am guiding with a finder guider and that my image scale is 1.49 arc seconds per pixel I am very happy with this.
I'm loving this "Hubble Collection" you've got going on.
Seriously impressive stuff.
Thanks, I wouldn't be doing so much hubble work if I had had some new moon time up my sleeve! Hopefully next weekend is kind to me!

My process is just made up as I go along but usually I stack the frames and combine them into a master colour image in maximdl, I then align the HA and this colour image in maxim.
I stretch the colour in PS with preference to the blue and red to make the histogram about the same shape as the green.
I then layer the HA ontop as luminance. The HA usually has some masked high pass filtering done to it, and then it is sharpened using "smart sharpen"
I adjust the saturation of the colour layer to taste and thats it.

Wow, that is stunning.
