Here's a region that deserves more attention. NGC346, 358/9, 371 - delightful fine structures and plenty of colour.
I spent tonight playing with collimation rather than serious imaging - but did a couple of 10min subs in Ha and O3 of NGC346 just to see how it was going.
This is just 10mins each of Ha+O3+O3 - enough to bring me back the next time the sky clears.
But I'm curious about what looks like an alignment issue in Photoshop - there is a fractional misalignmnet behween the channels and I'm wondering what the best way to manage that might be. Any ideas?
