Hi,

below a 1 st trial for narrow band, IC1386. C8, at 6.3, AVX mount guided with Lodestar

I have been struggling as nights are getting short in Sweden, and sky glow is no longer very much stable, continuous slightly getting dark and then lighter again (I need to eliminate a number of exposure at the beginning of the session, as the different lightness seem to mess up a lot when integrating and processing). So I end up with only selecting carefully :

4*600 sec for Ha

3*600 sec for Oiii and Sii each

all bin 2

so for only 1,7 hours in total, I am quite happy

but I think the season is finished now with those short nights for deepsky, I will need to wait late july
