47 Tucanae

[dugnsuz]

Hello...
Nice fine crisp, clear night in the Adelaide Hills tonight (8.10.07)

47 Tucanae (NGC 104)
Canon 40D, ED80 Prime Focus, SynScan EQ5 mount
20 x 30 sec exposures @ iso640

Unsure if stacking does Globs any favours!?:shrug:


Doug:thumbsup:

Hey Doug

Nice work. There is a lot more to this photo than initially meets the eye. Here is a quick and dirty re-process to illustrate what rich data is lying hidden in the bits and bytes.

Hope you like the difference!

Cheers

Thanks Dennis,
I've got another 20 or so lights I could add to this set!!
Cheers

Looks good Doug! Nice and sharp!
Stack the lot then push it hard. Should bring up the fainter stars a bit better..:thumbsup:

pretty good effort Doug, nice going, there certainly is a bit more in that image when you dig deeper. don't worry mate I'm having a hell of a time with this processing stuff, as well.

Thanks chaps!
I have tended to overprocess images in the past with the Pentax:whistle:
I tried to hang back with the Canon images. the Raw to Tif conversions are larger than the Pentax files(Pentax: 35Mb, Canon: 57Mb!!!) so ImagesPlus and PS have a tougher=longer time chucking them around.
Although, I have noticed that the images from the 40D require less processing after stacking which is a major plus - haven't been overdoing the PS actions on these images either...yet!:lol:
All the best
Doug:thumbsup:

Good stuff Doug.

Like Gary said, stack the lot and then re-process, you'll get more detail out.
The RAWs and Tiffs certainly bogg down the machine and fill the drive don't they.

Good work mate !!

Good start Doug. :thumbsup:

As already said, throw the lot at the image, all your Lights, Flats, Darks and Bias, use the ImagesPlus, Automatic Image Set Processing function, then really give the sliders a work out in the Digital Development area, specially the lower slider, it will bring out all your detail.

All I ever do after that is a slight Levels and Curves in PS.

Cheers

Good effort Doug. Don't hold back on adding those additional light frames to improve the S/N. Look forward to seeing more.

nice and sharp.... the standard around here is getting pretty high these days:)

Great looking image Doug, the widefield really does 47 Tuc justice.

It looks great just hanging there amongst the stars.

cheers

Nice and crisp to my eye Dug.
I think stacking particularly on globs, and particularly with T47 helps prevent burn out.
As already pointed out there seems more in this image to draw out..however it is a very good image and you should be very proud of your effort.

I would love to be able to get my stars as small as those in your image.
Well done.
