First light for my new baader 7nm Ha filter, it was a crystal clear night in Melbourne (although some smoke around) - gee it is good to be able to image under a gibbous moon
and to kick off before 9pm, school night imaging is back
no shortage of issues, stars top left in particular really bad (tilt predominantly - I think) and also the focuser tube was protruding into the tube which I think gave the funny star shapes - still getting used to how far I need to place the RCCi into the focuser (more it seems - that would avoid the focuser intrusion). Also am going to have to get a bahtinov mask -focus is difficult even with live view - not sure how the gurus do it with 3nm filters.
still - some nice detail to be had, my second go at capturing NB - zeroing in slowly and reasonable for a dslr.
Exposure was around 2hours 20 mins at 7 minute subs (iso 1600).
