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
