Final test that's impressed me with the new flattener, now I'm faced with weeks of cloud and rain {cry}
1hr 45 on North America and Pelican nebulas. I've tamed some halos - not sure what has caused these.. oddly one shoots off towards bottom left and the others towards the top right. Corner stars are far better now!
Altair 72EDF scope + dedicated 1x flattener
Altair 26C camera + Altair filtertray w/ Altair DuoBand HA/OIII
iOptron CEM25P mount
Guided by PHD2 with Altair MG32 package
Captured in NINA (21 x 300s)
Fully processed in PI start to finish - (inc. Darks and Flats)
