Hello everyone.
some things just need to be in B&W. I do have multiple hours of SII and OIII data on this 2 panel mosaic, but this Ha data is just worth looking at all on its own.
So this is just 5.5hours Ha around mag 2.23 Sadr in Cygnus (1.2Mb)

On the main page (

thanks for looking as always
Martin
