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) allows you to render the full extend of the glob which you've done nicely . 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

Beautiful!!

Why thank you.

You did a nice job in that image.
Yes that is the strength of the 16803/TEC180 combo wide FOV whilst still a lot of resolution.

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.

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.

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.

It's visually beautiful.

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
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

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.
