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:
http://www.stargazer-observatory.com/ngc4490.html
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 for looking - your comments and suggestions are always appreciated.
