Wow, Roberto is back in the saddle :P
Lovely images Roberto can you find us another AR3664 please.
Intersting combination WL and Ha.
Interestingly I just process Barnard 150 in Cepheus (not my image but part of a group processing chllenge for an American forum), it's an interesting area though my data was taken from a dark location in the USA.
Amazing from Petts Wood.
:lol:
Thank you Carole. I had taken another shot of B150 in 2020, also in June, and that was a better result I think: https://www.astrobin.com/full/padq19/D/ (https://www.astrobin.com/full/padq19/D/) Maybe because it had the Fireworks galaxy in it.
