About this image

Left mirror box with mirror cooling fan running for 6 hours outside before assembling the scope at 3am CET to get good thermal equilibration. Seeing conditions according to MeteoBlue: ~1 arcsecond seeing and jetstream speed ~ 23m/s. Conditions not bad, but not perfect either.

Captured about 20x5000 frame videos (frame rate ~ 100/s). Used AutoStakkert 3 and Registax 6 to process, typically selecting 10% best frames. Used WINJupos to align 6 best resulting frames.

Final processing (mainly colour adjustment) using AffinityPhoto.
