Description

This is just a "quick and dirty" approach to imaging M82. I wanted to test for the first time how binning (2x) affects the SNR and how details are affected. Well - as expected with a pixel scale of 1.23 "/pixel this is close to under sampling (assuming approx 3" FWHM of the stars). Therefore, some faint stars look a little bit like boxes. However, the impact on SNR is promising. One drawback was for me that deconvolution, this time, was not satisfactory. I guess that the stars are simply to "discrete" what causes artefacts at the edges.... Enjoy M82.
