50% SHO + 50% HOO Tarantula

Hi all.

I think I finally got enough data to finish this photo.

Currently presenting a SHO version. Not entirely sure about the colours, so will certainly get back to this data at some point.

Circa 10 hours per filter (all 3nm Astrodons).

The image is here: http://www.astrobin.com/full/233037/G/
Full resolution for closer inspection: http://cdn.astrobin.com/images/thumb...20Lipinski.jpg


All comments will be highly valued.

Thank you for looking.
S.

P.S. My attempt at NGC 2070 from last year: http://www.astrobin.com/full/141358/F/

Awesome! enjoyed that! (they are How good is that!? laughs)

The only thing I am thinking may make it look even better is if you can just get the stars to be more RGB'ish or even white'ish rather than red it would be good.

EDIT: Here Slaw, have one of these

Very cool, Suavi! Straight 10s from me too

If you do star removal for the colour data (and process luminance separately) you'll get clean white stars. You were planning RGB stars for this one anyway, weren't you?

Cheers,
Rick.

That's good! Took me a few seconds to find the spider. Your best to date and one of the best NB shots I've seen of this area. Epic.

Thank you Michael, Rick, Marc, Mike and Trish and Colin for your very kind feedback and comments. In terms of length of exposure, this is certainly my largest project to date

I have toned down star colour a bit (great suggestion!), but as Rick mentioned, eventually I would like to try adding RGB stars. Actually I found it quite tricky to create a perfect star mask that would cover all stars, plus I went wild with manipulating colour curves, that's probably why stars had strong colour

Hi Slawomir,
That is the wildest Tarantula I've ever seen.
I like the colours & everything about it.
Maybe you could add RGB stars but the picture stands as it is.
That would look nice if you made a large print & put it on the wall.

cheers
Allan

Certainly has impact Slaw! Big & Bold for sure.

I wonder though, is it just me or is the core is toned down too much as it's hard to guage where the light is coming from so it's looking a bit HDR as a result... and yes, as mentioned above those star colours need to be RGB imo.

Amazing details, clearly it's spider season atm

Glad you like it Allan. Yes, I went wild with this one LOL...and RGB stars will happen probably early next year.

Thanks Andy. My main goal was to show faint bits, so I struggled and partially failed to maintain 3D effect. I assure you though, no HDR has been applied in processing of this image

Edit: Following your advice I redid the luminance: http://cdn.astrobin.com/images/thumb...20Lipinski.jpg

That's so much better imo Slaw
It's my understanding of a David Malin thing, "Respecting the Light" as he called it, when he addressed us at the CWAS Astrofest this year.
He was very specific about how the Tarantula looks, and the core should be bright.

Also, the colours are a lot more appealing to my eye in the new version as well - One for next year's Malin awards perhaps?

Yeah hard to say which looks better really but I think I actually like the first version as it looks a tad more natural

As for this whole "respecting the light" palava... I know what it's all about and the idea is sound in some respects but it's not gospel, just one blokes opinion really. Presenting the Tarantula with a blown out core just because David Malin seems to suggest that's how it should look is well just crazy in my opinion. There is detail to be seen in there, so lets see it . As long as it doesn't look like there is a dark hole in the middle of the neb and you can pull it off as a graduated effect you can maintain the depth and see the detail, Steven Mohr's DM entry is a classic example of perhaps the best rendition of the Tarantula going and it is not blown out. The same skill becomes useful with M42 as well.

Mike

Thank you Michael and Andy for your suggestions and feedback. I think I need to leave it for a week or two and get back to it to see destination more clearly

Anyway, here are the versions I have constructed so far:

The original with whiter stars: http://www.astrobin.com/full/233037/B/

Brighter version: http://www.astrobin.com/full/233037/C/

Going blue...:http://www.astrobin.com/full/233037/D/

And the last one: http://www.astrobin.com/full/233037/E/

Thank you for looking

Some interesting colour schemes there Slawomir but I do prefer the original. It has more colour depth, punch and contrast.

One there almost looks like a polarised image.

Greg.

Mike, Slaw - David was directing his comments about "respecting the light" specifically to that image of Steve's by example, which in his opinion, was not bright enough in the core to show where the light was coming from.
He then showed us what he though it should look like!

Subjective? Yes.
Authoritative? Definitely.
Offensive? Probably!

I still prefer version two
