Hi Doug,
Good report mate -- an enjoyable read.
Yep, globular cluster season is upon us again and you've stopped in on a few of my fav's too.
M19 is very interesting from the point of view that it not even nearly round -- really quite oval elongated N-S (PA 0) as I recall and some good resolution in 12" -- very well resolved in 18".
M62 is also very underrated -- big and resolves pretty well with strong concentration to the core. It is one of the Milky Way's heavy-hitters among the globulars. Think it is number 8 of 157 in terms of absolute magnitude at mag -9.19 (not that far behind 47 Tucanae actually). Interesting.
And of course good 'ol M80 -- one of the most compressed clusters of all. A lovely sight, resolved into stars or not. From memory M80 is one of two Milky Way GCs is known to have hosted a nova. The other is M14.
Best,
Les D
