My first longer integration time object M106 in multi narrowband with the Optolong L-Pro for Ha, Hb, OOII, NII and SII and the Optolong L-eNhance for Ha, Hb and OIII
In total 15 and a half hours. It was more because originally I planned to mix broad- and narrowband. But the broadband just was a lot of brown/orange.
Processing all this was a challenge too: first time this much data and narrowband.
Plus a new record: all this is with tracking only with my Ioptron CEM25EC mount. And with the L-eNhance captures I managed to get close to 9 minutes unguided Just love that mount.
All in all I am pleased with the result. I lacked the best filter though: dark skies. I am in Bortle 7/8 and because of that I couldn't manage to capture both the secondary arms of M106. But already stoked that I have 1 of them
The main capture is scaled down to 2400px. Also processed the L-Enhance data separately and that one is not scaled down.
