Two more in Cassiopea

The moon was almost full last night but it was otherwise clear so I decided to try for the two Messiers in Cassiopea, M52 and M103. Both were fairly easy to find even though I was just barely able to make out the five brightest stars in Cas unaided. M52 was off the end of the southern-most end of Cas, the acute angle end of the W or the upper end at the time I looked. It was about the same distance as the length of the leg of the W. M52 looked like it's picture except much dimmer in my 8" with 27mm ep and an almost full moon. It was so bright out that I didn't need any additional light to set up or take down. While I was getting dark adapted, Mr Coon decided to come see what was going on. Before he could climb into my lap, I asked him what he was doing on my deck and he waddled off into the moonlight. We're building a pergola on the deck and all of his usual dinner food (cracked corn) was missing. He had to raid the compost pile last night. M103 was next and it was a bit harder to find than 52 but not much. There is a group of brighter stars in the middle of the cluster that sort of looks like a minature version of Orion and 103 is very near Del Cas, the northern most bottom 'point' of the W on the obtuse angle end. It also looks a lot like its picture.
All in all it was a fine night even with the moonlight and a quick and dirty look at two northern Messiers. It'll be good to revisit these in a darker sky.
