I love the intricate nature of this nebula.  Huge object too and quite astonishing how much exposure is needed to surpress the noise, I think you could be looking at 30 hours plus especially if you go colour.

Great effort Chris. Do keep going. ATB Jim

Thanks Jim

This target was one of the main reasons for getting the 135. I did it with the FSQ85/383 but even with a 2 x 2 mosaic I had bits missing! Its a great challenge object as even at f2.8, individual subs show very little of the nebula itself. 10 minute subs at f2.8 are very much sky limited so little point going longer and so the only option is collecting more of them! Could be some time.

Thats great Chris, ive always wanted to capture this object, never quite have the right field of view to do it though.

Very well done, Chris.  This is SUCH a difficult target.  I've tried it a couple of times now, but never managed to capture the beautiful structure and fine detail I see in your image.  Hope you are able to get good colour data to finish it.

Cheers,

Peter.

This is amazing imaging ! Just out of curiosity , can this been seen visually with or without a special filter ?

Can't learn if you don't ask , First step is the starting point !!

Ron , that is the best part of 10 hours worth of photon arrivals and on a faintness scale of 1-10 its a 12 so I doubt very much if it would ever be seen visually. The veil nebula has a much higher surface magnitude and thats a struggle until you look through a big scope (and even then its a bit of a smudge).

I saw the Veil Neb only once in my life . It was at a star party , guy used a Orion 12" dob with a two inch Tel-Vue EP and a nebulae filter (not sure the brand but I think it was a Lumicon 2? OIII Oxygen III filter . The Veil stuck out so beautifully it was amazing !!

Without trying to hijack this EXCELLENT thread photo too much... (sorrrry Chris).... got to agree with Celestron8g8....  I have seen the Veil a number of times through a variety of scopes over the years at Kelling... and with an OIII filter is striking what faint filaments you can see with a good set of optics.... very faint... but, as Chris says, one of the brighter (barely) supanova remanant!

Especially when you think of what is typically needed, exposure times related, to get a decent image!

Really great image Chris and such detail in sooooo faint a target.
Keep it coming and look forward to an APOD in the future.
