I needed several nights to obtain the narrowband data (Ha, OIII and SII) for this picture of the IC5070 region.
I used my Takahashi FS102NSV @ f/6.2 and the QSI532WS-M1 in a ATLAS mount. Processed in the HST palette (SII:Ha:OIII).
Beautiful! Could you tell us more about exposure times?

Thanks, I'm glad you like it.
I made 20x12 min subexposures for each channel. So, 4 hours for each channel (12 hours total exposure time). I use Baader narrowband filters: Ha-7nm, OIII-8nm and SII-8nm.
