hi guys,
I returned from London astrofest yesterday and brought a new CCD along.
it is a monochromatic Stalight Xpress SXVF H16 - 2024 over 2024 pixel; 7.2 micrometer.
fortunately the night was clear, seeing decent and transparency fairly good enough for some FL...
here is the data:
9" TMB Apo folded apochromatic refractor (the 'big boy'...(-
SXVF H16
L: 1x1 bin, 15x9 min; no darks
R,G,B: 2x2 bin, 7x9 min; no darks
image acquisition in astroart 4
preprocessing in maxim, registax, ccd sharp
postprocessing in Ps CS2 and Pix Insight LE
color balance by trial ( i did not want to waste time with a g2v procedure last night, as I had to take all advantage out of that nice conditions...r=1.3 g=1 b=1.1
all images can be found here:

I must admit, irregular galaxies are both, most beautiful and fascinating for their star burst acitivity.
I did one last year, when I tested H16:

THANKS Brian(-:

friends,

I was a bit unhappy with the core region.
so I reprocessed luminance data to let the core now stand out with
some sutile detail.
also I enhanced colors a bit and applied a bit more deconv...

I'm glad you got the camera, Diets.....you did such a good work with it when you were testing it.......now I look forward to the great images that you will be showing.....

this is one of them...really nice detail, color and depth....I like these unusual/non standard galaxies.

thanks for sharing
