Hi all, it's been a pretty wet and wild winter here in Perth and I had some work to do on the imaging system, but it's all sorted and starting to work nicely for spring. I managed to get a few clear nights over the last weekend, so I went for some narrowband data on M16. This SHO composite is made up of about 9 hours worth of subs - I lost a few subs to dew, which I didn't think was meant to happen inside a dome.
Scope is the ASA16"f3.6, camera is the QSI683 using Astrodon 5nm NB filters. Subs were 15 minutes unguided on the DDM85XL and processing in PI. I guess NB colour is always a question of taste! I've also linked to a less cropped image on astrobin, but I'm very pleased with the detail.

cheers, and thanks for looking!
