Still working here. Kind of a hassle because I shot the short core exposures on a different night. Anyway, the steep part of the learning curve is the fun part!

Amazing detail in the outer nebulosity milby, looks like with this last image you are getting to grips far better with the layering and blending of the core, very nice indeed.

Haseeb, only just noticed your attempt wide field at M31 not bad considering the problems, and you did at least capture a dark lane.Plus M32 and M110

best regards,

Tom.

Thank you Tom, appreciate it.

Milby, this latest process shows good contrast and dynamic range.

Wow! That one is a keeper, Milby! The Trap is easy to pick out ( I can see all four [A, B, C, D] stars) and the outer nebulosity is beautiful!

Nice layering and colour blending, Milby, bringing out the Trapezium excellently while preserving those more tenuous filaments !

Best regards,
Tel

Hi All,

With Christmas rapidly approaching I thought it would be fun to target the Christmas tree cluster. I want to capture some Ha data at some point but thought I would share.

Thanks for looking and Merry Christmas!

Best,

George

Congratulations on a fine "Christmas Tree", George !

Any chance of providing some imaging details, please ?

Best regards,
Tel

BTW. Perfect pitch on the diffraction spikes but curious to know where they came from ?

Thanks Tel and Art.

Tel, I added the details to the original post. The star spikes were added using the Star spikes 2 filter for CS5 from Noel Carboni. It is a neat little program, not perfect but gives an option to try something different.

Best,

George

Absolutely, George !

I too experimented with "spikes" some time back as part and parcel of another processing program I have, (Photoimpact 8), but had mixed feelings about their use.

Probably I was overdoing them at the time. Certainly mine were in no way as tastefully applied as yours !

Best regards,
Tel

Tel,

I initially over did the spikes as well earlier this year and cringe now when I take a look back. For some reason this image seemed to call out for some experimentation! If I ever get the courage to put the C8 on the CG5 I would like to image this again at a higher focal length. The core is just so interesting to look at.

Best,

George

Excellent Christmas tree George and very Apt for the season

Wish i could join in with all the fun of imaging,but with our current UK weather, it looks like it will be the New Year before my dreams come true.

best regards,

Tom.

Your Ha images are brilliant to say the least. I think you now have a sufficient library to make a book.

WHICH new year Tom?

I'm guessing not 2012/13 given the amount of water which is falling and the wall-to-wall could cover

Hi Art, its all very depressing watching weather forecasts, seem`s like the UK is sinking under all this damned rain.

Still, i would like to wish you, and all here, a very merry Xmas, and at least its good to know that somewhere on this globe of ours, that there`s clear skies somewhere, which allows us to view the wonderful images all here produce.

best seasonal wishes guy`s,

Tom.

Beautiful work! Nicely subdued use of the spike effect. I would not have guessed those weren't real diffraction artifacts.

Tom, Tel, Peter, and Art,

Would you guys please share some of that rain with us! Here in North Texas we are dry as a Saharan sand dune. Although we have clear skies (nice for us stargazers), we need that rain badly.

Thanks and a very Merry Christmas and a happy and prosperous New Year to all,
