Coincidentally Suavi & I are both targeting the triffid in narrowband at present. :)
Just for fun it seems that we're having a Trifid - off, so here's a hasty opening shot across the bow, from last night with not nearly enough data! :lol:

The plan is to keep big Mike and others happy too, by creating some kind of NB/RGB hybrid from my light polluted suburban skies in Melbourne.

This is a B-HaR-O3B-G cocktail which shows some promise using a seperate Blue layer as LUM - never tried this before :help:

I've attached screenshots of the masters for interest, I'm amazed to have so much blue signal already.

Only 2hrs Ha, 2 hrs O3 & a mere 20mins ea of RGB so far. The plan is to add S2 & a LOT more data to smooth it out properly.
(Hmm - I also have an N2 filter? :question:)

Like M42, this object seems to appear better in broadband, so it's a challenging technical exercise to try for a pseudo-natural result using the NB & broadband filters. :)

Come one, come all- anyone can play :)

Here is the work in progress (http://www.astrobin.com/full/413341/0/) - (don't pixel peep too closely, it's got a long way to go yet!)

It’s WAR! :lol:

10” against 4” so a wider field against the narrower. Could be an interesting stand off ;)
It’s showing promise so far Andy.

The triffid is one of the most beautiful objects in the sky ...and sorry, I'm not a fan of NB versions.....The colours of the Sistine Chapel vault are just fine without any tinkering IMHO :)

To accurately nail sky-blue reflection nebula colours plus the H-alpha + beta and dust is not easy.....I think Malin's seminal versions are worth a look to guide your progress :thumbsup:

Waiting for the return salvo! Everyone keep your heads down, we don't want anyone to get splattered with photons, ok? :lol:

It's an interesting challenge Col - I have huge respect for Suavi so I'm sure he'll produce something amazing with his 4" frac :)



Thanks Peter, I've just found that original AAO Malin image - something to aspire to indeed - not sure how I'll go under LP conditions but will give it a good crack :thumbsup:



Lol :lol: Load photon Torpedoes! :lol:

Thank you Andy - I hope you are getting some clear skies to make progress with the project - I really look forward to your bold, inspiring and eye-catching interpretation of the Trifid :thumbsup:

Looking good overall Andy. No star colour though, all white.

Overall though the image lacks punch, a bit early to comment though.

That red area is somewhat muted to me eye.

Martin Pugh did a lovely hybrid version a few years back that would be worth referring to.

Greg.

Nice Andy. So is this worth trying narrow band?

Hey Suavi - We've had a rare and welcome run of clear nights here in Melbourne. Project now completed - will post up the results tmrw.:D



Thanks Greg - stay tuned on this channel for an update tmrw :lol:



Definately - otherwise everyone's Triffids would look alike :D
