Description

M 82 has massive star clusters in its center, which were partialy resolved by the HST (see Halpha data). I tried to get some details in these clusters using short exposures. Not easy to do :

ASI 290 MMC : 35000 x 200 ms out of 50000 with red filter at 2450 mm focal length using an APM 1,5 x corrected Barlow. I got a little tilt and had to crop the image.

ASI 290 MMC : 7500 x 1 second at 1650 mm focal length (primary).

ASI 294 MC Pro from here for the color :

I use TOPAZ Denoise (trial version) instead of deconvolution.
