Start May 16, 10PM
Equipment:
Hardin Optical StarHOC 6" F5 Newtonian
30mm Celestron Ultima: 25x, 2.0 deg
12.5mm Celestron Ultima: 60x, 0.8 deg
M68: visited this again from the balcony with the medium aperture scope.
Much easier to see than in the 66mm ED Doublet refractor on May 12, but
still quite dim in the glow of the light dome to my south. No individual
stars could be declared, but were hinted at near the far edge.
Definitely not a single star, or a galaxy. Globular cluster-like
granularity was pretty obvious.
M3, M53, and last but not least, M5 just clearing the trees before I
quit. All easily detectable as globulars, with individual stars at the
edges.
Quick look at Saturn to the south-southeast, and the moon approaching
the horizon in the west. Earth-shine was obvious.
Stop May 16, 11PM.

Scopes:
Small: AT66 66mm ED Doublet F6/400mm
Medium: Hardin StarHOC 6" Newtonian, F5/750mm
Large: Zhumell 10" Dobsonian F5/1250mm
Mount for small and medium scopes: Unistar Light
(While the 6" F5 Newt is a too large scope for the Unistar Light mount,
I find I can manage well enough with the combination to be functional at
the low powers that I use this scope for)
