M27 - Dumbbell Nebula, RASA 8", 3 hrs

Jul 29th, 2026

1 h 42 m

Following an old tradition, M27 must be captured every year on July 27. And, by the same tradition, each year it has to be captured in a new way. This time, the plan was to debut StellaVita, but you can't just quickly set it up and work with it — it even lacks the functionality for manual focusing, and everything is just poorly designed. It might be usable, but first you have to suffer through it. So, by midnight, I had to quickly disassemble Stella, reconnect the old reliable Nina, and then shoot for 2 hours "without a single break." I'm surprised how much is visible in the frame, considering this is the most basic ED80 F/7.5 F=600mm, captured near Moscow and aimed toward Moscow (some main stars of major constellations aren't even visible to the naked eye).
