47 Tucannae

[gregbradley]

I imaged this one last year and only catching up now.

TEC180FL, FLI Proline 16803, Baader LRGB filters.

LRGB 24 16 16 16 16 with a core of 60 second shots.

That is far and away one of the best pictures of 47 tuc I have ever seen! :O Well done indeed sir :)

The contrast is fantastic!

Doesn't look like 47 Tuc to me.

Visually 47 Tuc has a stellar like core, but you've processed it to look like Omega Cent with, I guess, mid range stretching hence stars have lost their intrinsic colours, with an artificial magenta mid halo, and many staurated to white.

This is a commonly imaged object, hence it's easy to fnd a baseline of comparitive images... my effort from some years ago probably gives a better idea of what I'm on about....

I think you got some good data there, justs needs a little tweak here and there...

Hi Greg. Your FOV (similar to mine here (http://www.pbase.com/gailmarc/image/103785965/large)) allows you to render the full extend of the glob which you've done nicely :thumbsup:. Many images of 47 Tuc just don't manage to do that.

I do agree with Peter though that you've homogenised the brightess gradient at the core and lost it's stellar like appearance - a defining feature. Your star colours would benefit from some enhancement as well.

Cheers, Marcus

:eyepop: Beautiful!!

[gregbradley]

Why thank you.



How you handle the core is important. It like M42 is often shown as burnt out. Here I wanted to have it show some detail perhaps at the expense of being extremely bright. I'll try another version to see if I can retain that super brightness without burning it out. Daniel Vesrchase's version was a model I followed for this which I liked the most. So to some degree that may be a subjective choice. Colour data seems weaker than in other versions I have done of this. Not sure why. Perhaps in the colour combine step it needs more boosting.



Thanks Liz.

Greg,

I like your treatment of 47 Tuc.

Nice work Greg. I've found 47 Tuc to be a difficult target to get right. Its core is considerably more dense and brighter the other globulars. Hence requires a different approach when processing. I like what you've put together. Well done.

[gregbradley]

Thanks Frank.



Thanks Jase. There are choices to be made in how its done that will affect the final image.

Nice one Greg - certainly a very deep shot. You've captured the other clusters around real well. :thumbsup:

[DiamondDust]

It's visually beautiful. :love:

They say Beauty is in the eye of the beholder.:)
But I don't think It is one of your best :(
When I first looked at it I just didn't like It, to me the core is too burnt out:shrug:
With the equipment today and the skill of people like yourself to me they shouldn't be just blobs in the middle:(
No Offense intended:thumbsup:

[gregbradley]

Thank you.



Art is totally subjective and I agree the core could be less burnt out. I took 60 second exposures for the core and I think they should have been 20-30 seconds. Again I may reshoot the core if 47 Tuc is still up.
Also will try to get some more colour.
Greg.
