Description

A few minutes left after a (too late) Jupiter and Saturn session, left the 2.5x Barlow and took a few 4 second unguided images of M 27.

DSS failed to stack them (probably FWHM too large with 0.256 arcsecs per pixel).

Therefore tried SiriL for the first time, which actually succeeded with stacking.

141 images a 4 seconds used, further processing with FitsWork, a little bit of wavelet filter, but I like the high resolution. M 27 is larger than my FOV.
