The next opportunity I returned to the 300mm for some wider views of familiar objects. I selected the area centered on The Bubble Nebula but found that the spill from the the church tower floodlight was at its worst in this area of sky so the subs were badly washed out despite an otherwise decently transparent sky. The resulting image is therefore lacking in depth but shows the cluster M 52 quite well. Details: Tair-3S 300mm@F5.6 . 12x 8 minutes @ iso1600 (full field) with CLS in DSS, FIV, CS2 & XAT
