Hi,
managed some h-alpha imaging this morning since there was a unexpected gap in the cloudy weather, seeing was "medium". Weatherforecast in general is depressing here atm : )
(Quark Chrom. + reducer, Stack of best 50/1600 images, 9ms exposures, Gain @ 210)
Nice weekend to you all.
First h-alpha this year for me, 18.03.2023
