Hi all,
Here's Version 2 of one of my latest images - Messier 20, the Trifid Nebula.
This version of this image is masked so to retain detail in the central
brighter parts of the nebula.

It is a 62 min. exposure (25 x 150 sec. sub-frames) @ ISO400.

Higher Resolution Image: http://www.skylab.com.au/pmsa/ngc6618b.html

The image was taken with my observatory mounted 12-inch f/5 GSO Newtonian telescope on a Losmandy Gemini G-11 equatorial mount. Autoguided with SBIG 402 on 4.5-inch f/9 guidescope with 1.6x Barlow using CCDSoft. Camera Canon EOS 300D Digital ( Hα enabled ) focused with DSLR Focus. Used a 2" Baader Multi-Purpose Coma Corrector (MPCC) and a 2" Baader UV/IR Rejection Filter. Image Processing Iris, Photoshop, Noiseware.

Clear Skies!
Paul

Thats a beauty Paul, great colour and detail.
The Blue part of the nebula really does extend a fair way out, I never realised that.

Top stuff

Yes indeed. Lots of subtle colours and detail present. As they say 1/2 the works at the telescope, the other half at the computer processing. Its amazing what can be brought out with careful processing like that

Thanks everyone for your comments. I certainly agree it's amazing to see how much the nebula extends.
