It felt so good to be back out doing astrophotography this evening. Had a quick but ultimately unfruitful play with an experimental imaging train but reverted to 100-400mm telephoto lens + astro camera to get some data on the Cygnus Loop with the new(ish) IDAS NBZ dual-narrowband filter.
Still a week to go before astro-dark returns after the summer, but … at 7ºC I had to put on a jumper whilst faffing with the telescope. Definitely a sign of doing it properly :)
