M48 Somewhat scattered, Very Bright, can be seen naked eye, 12 stars are resolved in 8X50 finder, many chains of stars, little compressed, 7 *'s near center form an arch or boomerang shape. One * 9 mag orange at 60X.
AZ city-- just naked eye, 12 stars in 11X80. 13" 60X (38mm Erfle)--bright, very large, pretty rich, little compressed, stars 9 to 13th mag. No fuzzy background, seems all stars are resolved. There are several chains and bright members. 61 stars counted in cluster.

6" f/6 48 stars counted using 22mm Panoptic, cluster is bright, large, rich, somewhat compressed, has a nice chain of stars in the center of the cluster that forms a "bar" across middle.

6" f/6 S=5, T=6 Eagle Eye Rd. 33mm--bright, very large, 28 stars counted, 12 in bright E-W chain in the middle, pretty rich, pretty compressed, stars of 9th mag and less. 22mm--44 stars counted, few really dim members, no fuzzy background

2610 Pretty Faint, pretty Small found at 100X, better at 165X.
300X too much. Star in neby is easy, neby is comet-shaped. Reminds
me of a small and faint Hubble's Variable Neb.

3242 Wow, Looks like CBS eye, greenish at all powers, Central star easy at 300X. Very bright, large, round. AT 650X on a night I rated 8/10 for seeing, there is a small, dark circular area around the central star. A very nice planetary with lots of internal detail at high power. Sentinel 13" 8/10--100X bright, pretty large, little elongated 1.2 X 1 PA 135, central star comes and goes with the seeing, light green or aqua. 220X--CBS eye obvious
dark background and bright oval that encompassed the central star. Still very light green. UHC makes the central star disappear. 440X--Best view, several bright knots to southeast of central star, bright spots within CBS oval. High power shows the color as grey, not green, but high power brings out most detail, including central star and bright knots in disk.

20" f/4 TSP 13mm Nagler + Parracor Central star 20% of time,
CBS eye feature easy, light green in color, aviz doubles the
size of planetary.

36" f/5 TSP 96 Larry Mitchell's scope 14mm Meade UWA--Bright,
large, lots of detail, 3 levels of brightness, central star held
constant, dark ring around central star, very dim outer section
with averted vision. Great view, medium green at all times.
A few bright knots in the brighter nebulosity that forms the
CBS eye.

Hydra Galaxy Cluster I, on a night near Kitt Peak that I rated 8/10 for seeing and 9/10 for transparency, all observations done at 165X.

a few spirals.

M68 Pretty bright, Rich, Compressed, seen in finder. Resolved at all powers. "Kidney-shaped" with steamers on one side. About 50 stars resolved at 165X. Many stars at the limit of 17.5", averted vision makes it grow. At 300X the core has about 10 stars resolved and the central area is very grainy. Entire cluster looks like a garden sprinkler, with extremely faint stars seen as a set of curved chains that exit the main body and swirl around.
Sentinel 13" 8/10-- bright, large, extremely rich, extremely compressed, bright middle, irregularly round, stars 13th mag and less. Easy in 11X80, very comet-like in finder.

with 3 to 4 arc sec in size, many bright areas in arms.

36" f/5 20mm Nagler TSP 96 spiral easy, aviz makes the spiral structure more obvious and increases size 30%. Many small knots in the arms. Amazing amount of detail. Core a very light yellow.

5694 Pretty bright, pretty large, Round, brighter in the middle; 165X and 320X, very grainy, no resolution on a night I rated 5/10. At a much better site on an evening I rated 8/10 the 17.5" would show 6 stars superimposed on a hazy outer corona.
