nGC 2736, the Pencil Nebula

[Geoff45 (Geoff)]

I've had a bad run with the weather, so I've taken to trolling through my archives to see if there were things that could benefit from a repro. I dragged out this one from January 2013. I wasn't really happy with the first attempt that I did at the time, so I never posted it anywhere. This one is better.
Telescope: William Optics ZS110 Refractor
Exposure: 200minutes spread over equal numbers (more or less) of R, G, B, L

Excellent Geoff, pretty deep. I had a go in NB, not good, although its a neb, it does look better in LRGB.

Thanks Fred. It does emit pretty strongly in OIII, so maybe throwing some OIII into the green channel would be a good idea. I'll be having another go at this with my 12.5" and new Proline 16803 when it's in a good position.

Whoa, a Proline 16803!. Quite an upgrade . Interesting to see what you do with that. 3nm NB filters too perchance?. Exy .

Not yet. Proline +7 position filter wheel+MOAG+7 filters (L, R, G, B, 12nm OIII, Ha, SIII)+connectors to PlaneWave didn't leave me with a lot of spare change. Maybe in the long term. Even the 12nm filters new are $500 each, although I managed to score these second hand at half price from Mike Sidonio.

Nice Geoff! Looking forward to seeing the result with your new camera.

Just checked the price. Exy is certainly the word! 3nm 50mm square Astrodon filters are $US1250 each. May be some time before I get a set of these.

Nice job, Geoff. LRGB works quite well for this one which I wouldn't have expected.

Thanks Rick. How would you have tackled it?

[Placidus (Mike and Trish)]

Hi, Geoff, Lots and lots to see in this wider shot. Bok globules and dust lanes off to the right, and a meshwork of really faint stuff to the left of the pencil. I can see from your shot that I mis-framed my most recent effort. Great work. Best, Mike

Haven't really thought about it, Geoff, but most (all?) of the images I have seen have been narrowband. The received wisdom isn't always right, of course, as you've demonstrated.

Cheers,
Rick.

That's a little more interesting than I usually see that field presented, lots more going on and to see than usual, different colors, so well done on that score It suffers a bit in the warts department when viewed large though..but meah, still a very interesting image, enjoyed the view.

That's a beautiful image. Lovely colours. Very well exposed.

Thanks Mike. Yep, the warts are there. In fact I was a bit hesitant to post this one because of the said warts. I think I can clean them up though if I go through a more careful repro.

Thanks Marc. It's surprising what you can do with an image that you'd written off.

Hi Geoff,
I really like your pic.
I believe I could make it even better with a few minor touch ups -
mainly a star mask to reduce star sizes & a slight colour boost & more contrast.
I'll post another version if you want?

cheers
Allan

Great looking photo Geoff.

Very nice colours.

Ross.

Thanks Allan. Go ahead and post. Nice to see what someone else makes of it. I actually didn't go all out with this one because my first processing attempt two years ago was a real bummer, so when I did a quick repro and got a much better result I stopped there. Now that I've got so many positive comments I'll have a more careful go at it.
