Yesterdaynight was clear so I decided to photograph an old friend that I watch very often with my 10x50 binocular. NGC869 and NGC884: The Perseus Double cluster. The total exposuretime was 3hr10min, consisting of 13x10min autoguided ISO800 and 6x10min autoguided ISO1600. After the session the water dripped from the guidescope. The main scope was also starting to fog (despite the heaters) because of the moisture in the air.
