Description

Revisited the magnificent Double Cluster (NGC 884 & NGC 869) in Perseus. When compared to the previous take from last year, the progress is noticeable. Still, I feel like it can be done better, though I will need a better mount for this. The EQ3-2 is just not meant for long exposure times. Luckily, open clusters such as this lend themselves to shorter exposures very well.
