Pick these two up in the same field with the 42 mm (c. 2-inch) diameter lens
by GSO. The seeing is exceptional for this latitude and time of night (c. 11:30
PM EST). M97 is at the top of my view, showing its round face like a smudge of
faint white dust with no other detail. A little below it runs the gash of 
M108, also like a faint white smudge, both at the same (?) magnitude. A small 
star is equidistant between the galaxy and planetary. The view is soon 
occluded by high thin clouds, blanking out the view entirely.
