Another milestone! My first full narrowband image. After installing my autofocuser, I've minimised my time outside and decreased the number of mosquito bites by half. That in itself is worth the investment. Just a very rough polar alignment that gave me an RMS of 1" so I was limited to 5min.
This is also the first image I'm happy with coming out of my very expensive (to me
) esprit 100ED.
15x 5 min of each filter (Ha, Oiii, Sii)
