Ic434 - Colour Added

Hello all

Well, I certainly hope I get to finish this as the luminance shows much promise.

I have combined 5 hours luminance and 5 hours Ha through pixel math to produce the final lum in what will hopefully be a (Ha+Lum)LRGB production.

So, just in case I run out of time or weather denies me the last few colour frames, I thought I would post this first up.

12.5" RC, SBIG STL11K, Astrodon 6nm Ha filter and Gen2 Lum....all AO-L guided.

thanks for looking and clear skies.

Martin

Very nice Martin. Hope to see the final colour image. Should be worth the wait.

Lovely work yet again Martin! The finished result should look rather spectacular. Interested to see how you'll manage the flare from Alnitak. Caused me considerable headaches in a similar image which I'm still working on. Stars look incredibly tight, do you use the minimum function then fade the action to 40%-60% by any chance? The AOL would help, but not to the level you've presented.

Nice image Martin.
I feel that monochrome images are more dramatic, specially the oft-imaged targets, pure and simple data.
The detail is esquisite.
Well done.

Beautiful.

This is going to be a stunner Martin!
Wow, what a field your getting, nice equipment of course.

Probably one of the best on the HH once you get some rgb's to go with this lum.

You're certainly stepped the bar way up there.
Keep 'em coming.

All the best
Rich

Excellent work Martin. I know it will be spectacular with colour but I'm quite enjoying it just the way it is.

I can see those tiny, faint galaxies above the horsehead. I first saw those in an AAT image!

Thank you very much.

Alas, the weather forecast has changed, and while it is only a forecast, prone to changing in just a few short hours, I am in with the chance of 4 or so straight clear nights...so I might just get to finish this.

Jase...no minimum filter required. The proper combination of luminance and Ha took care of the stellar widths. In fact, I only followed up with deconvolution as an after thought (just 30 iterations of Pos Constraint). The challenge of course will be to blend the RGB while maintaining those tight stars.

I know what you mean....I have already cropped out massive reflections imposed by Alnitak....I do not plan on expanding the FOV. However, it is amazing what moving the scope a little and then taking some short frames achieves. This becomes a 'patch' frame to mask this stray light....I've got those frames, but dont intend to use them.

thanks for the comments all....I appreciate it v.much.

Ooopss...its clear, and its dark....time to cool the optics and roll back the roof!

cheers
Martin

An excellent image Martin, as expected, but I dont see a much of the verticle gass lane streaks I have seen in other images of this calibre ?.

Most excellent data Martin. I would had to have gathered 20+ hours from my urban locale and suspect would still not get the S/N your image shows (damm those Yass skies )

Crappy Sydney has ensured I have done virtually no imaging of late...hence am also impressed by your tenacity to have found skies clear enough for a good imaging run.

Beautifully tight round stars, super smooth data. Brilliant stuff!

Thanks Fred/Leon/Peter.

dont worry Peter....have been suffering the same withdrawal symptoms as most (unlike Mr Gendler who has bagged yet another APOD today with his LMC shot from Pingelly)...obviously WA is the place to be.

Fred...I know what you are referring to....but I do see those streaks on my monitor? There are plenty of them there with 10 hours exposure.

cheers
Martin

I've seen better.... on hubblesite.org

As for land based scopes, I think this is easily the most detailed horse I've seen.. I very much look forward to color.. (not that it needs it, its a ripper as is.)

Another masterpiece

Once it's in colour, it'll be good enough to eat

Great work.

IC434 - Colour Added

Hello all

Well, I managed to squeeze in the remaining colour frames and now sadly the weather has moved in for the next few days at least

So this ended up being a HA+Lum RGB of 5:5:3:3:3 hours exposure..

Many thanks for the additional posts, and I certainly hope you like the final colour version.

best regards and clear skies

Martin
