M96, spiral galaxy in Leo.  About 38 mln light years away.


Image info

Telescope:  Skywatcher 8" f/5 Newtonian

Focus:  Prime focus

Camera:  SAC7B, uncooled

Exposure:  52 x 25s 

Date:  2nd Feb 2003

Processing:  Acquired in Astrovideo as FITS.  Stacked in Iris and wavelet noise reduction.  RGB exported as 16 bit raws and image finished in Photoshop  Some additional noise reduction in SGBNR.


This was one of the first images where I exported the stacked image as 16 bit raws and did the histogram stretch in Photoshop.  The smoothness of transition from the faint outer regions of the galaxy to the sky background attests to the benefits of this technique.
