Description

NGC 281 captured over two nights. Planned to add another two hours last night, but clouds appeared well before te target was even high enough. Will retur as time and sky permit to expand data set.

Primarily 180s subs, but also a set of 300s subs which I captured when I wanted to boost exposure time to see more detail in individual frames. Only [11] of these as capture again curtailed by clouds.
