NGC 4490

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:

Dietmar,
Very nice images. I like the color and the detail. These are amazing targets.

Look at the amount of those tiny galaxies around the main object... amazing... 8O

congratulations...

Nice image Dietmar, and great rig. I am sure you will love that cam. I have a friend that might be getting one, and I surely hope I can coax him to come over and throw it in my scope for a bit.

Stunning image Dietmar! Fascinating object too.

Thanks for bringing to my attention: I may try my luck at it in the next few nights if the seeing and the weather assist me!
