Hello to all, let's take advantage of this easter weekend and a nice blue sky to go and see the sun :) At the fs60 with its sm40 double stack, BF10, glasspath x1.7 and zwo178mm on April 3rd around 15h10 UT S20210403-15h08UT-sm40DS-fs60-bf10-gpx1.7-asi178mm.jpg S20210403-15h07UT-sm40DS-fs60-bf10-gpx1...

good evening to all, despite a rather milky sky, I took out the equipment to shoot our favourite star before it sets. At the fs60 with its sm40 double stack, BF10, glasspath x1.7 and zwo178mm at about 16:15 UT S20210402-16h12UT-sm40DS-fs60-bf10-gpx1.7-asi178mm.jpg S20210402-16h13UT-sm40DS-fs60-bf10-...

good evening to all, sunshine in ultra fast mode tonight: just enough time to set up the equipment in my garden on my way home from work, and the sun is still just above the neighbour's roof. http://www.astrosurf.com/ls35dx/new52/S20210329-matos.jpg At the fs60 with his sm40 double stack, BF10, glas...

Autostackkert 3 is a good choice for the treatment of prominences. - for wavelets (much better than the AS!3 sharpen), use either regi...

hello,

in attached files, at least we are sure that it displays correctly

with kind regards,

Good evening to all, blue sky today from my house ... except where there was sunshine! a bit frustrating !

good morning to all, The sky is still clear in the Vosges mountains in France, even if a little milkier than yesterday.
