An interesting and bright target for summer and autumn nights !

Fresh H-alpha shape from yesterday (R~20K):

Interesting to be overplotted with BF Cyg, Ha-thickness is very similar (without deep outflow) and around 6515A(?) it is also having a sharp tiny feature (not a hotpixel !).
It was taken through thin veils so that H2O is very much present.
SNR is good, the 3 x 10 minute was needed only to have continuum also fine (and this was my final target). Someone might try short exposures.

Happy hunting!
