Program stars: AG Dra, AG Peg, CH Cyg, BF Cyg, Gam Cas

Results from last night with LHires III + 2400/mm + ATIK 414 EXM + 25cm Newton (+APM barlow), I could push out -9C temperature instead of the ideal -15C.
All results stable around R~20K reported by ISIS (anyway 23um slit).
I think AG Dra H-alpha line is getting complex, I'd appreciate confirmation:
5 x 10 minute exposure, still noisy (unexpected to me) though I optimized focus and guiding.
BF Cyg is slowly closing back, sharp edge U shape of absorption:
Last was 8 x 20 minute, an object that allows to sleep.
AG Peg, 10 x 3 exposure, I think the middle(!) of the H-alpha is showing a flicker, see this anim gif:
CH Cyg (3 x 5 minute):
Gam Cas (11 x 15 sec):
Once I was trying to checkin this object to BeSS but failed, I must invest more time on docs how to do it.
Cheers,
Peter
