Observing Notes

Andrew Cooper
Jun 29, 2019    Kaʻohe, Mauna Kea, HI (map)
8x42mm Nikon Prostaff 3S Binoculars @ 8x
Seeing: 8 Transparency: 7 Moon: 0%

Bright, not resolved, a round fuzzball in the binocular field, good sized, brighter to the center fading radially, quite easy to find

20cm f/6 Newtonian, Cave Astrola @ 102x
Seeing: 8 Transparency: 7 Moon: 0%

Absolutely beautiful, a stunning swarm of stars filling the field, large, bright, patially resolved

46cm f/4.5 Newtonian, Deep Violet @ 175x
Seeing: 7 Transparency: 6 Moon: 24%

Simply spectacular! The cluster fills the eyepiece, well over ½° across, with a swarm of stars. gradually denser to the center with no sky visible between the stars, only innumerable fainter stars filling the void, an excellent object in the 18", always worth a few minutes in the night to marvel at this wonder

46cm f/4.5 Newtonian, Deep Violet @ 175x
Seeing: 6 Transparency: 7 Moon: 0%

A mind boggling mass of stars that fills the field, an uncountable swarm, the cluster is larger than the 28' field of the 12mm eyepiece, the central condensation seems to be about 20' across with a peppering of brighter members against a solid haze of unresolved dimmer stars through the central region

To see this, to understand what it is, to realize the scale, the sheer number of stars. This is to know that the god of Abraham, as described in the Bible, is pathetically inadequate.

76mm f/6 APO, TeleVue-76 @ 14x
Seeing: 7 Transparency: 7 Moon: 0%

Large, bright, easily visible to the unaided eye, even at low power this is an impressive object, viewed without then with supplemental oxygen, first view showed the cluster but it seemed soft as if slightly out of focus, with oxygen the detail in the cluster is far more remarkable, the cluster is visible to a greater extent and much better resolved, crisp and sharp

15cm f/5 Newtonian, Primero @ 55x
Seeing: 7 Transparency: 6.5 Moon: 0%

Big!! Bright!! Stunning even in a modest telescope, an intense ball of stars filling the field, fully resolved, visible to the unaided eye

Apr 5, 2007    Hale Pohaku, HI (map)
15cm f/5 Newtonian, Primero @ 97x
Seeing: 7 Transparency: 7 Moon: 0%

Stunning! Large! Bright! a ball of uncountable swarms of stars filling the 37' field at 97x, recent discoveries confirm the presence of an intermediate mass black hole at the center suggesting this is not a globular but the core of a dwarf galaxy that has been absorbed into the Milky Way

May 24, 2006    Gila, NM (map)
46cm f/4.5 Deep Violet

Enormous swarm of stars, fills the 25' field of the 12mm Nagler, very bright, very large, fully resolved to the blazing core, hard to believe such and object exists as it seems so unreal, conditions decent to the horizon tonight allowing appreciation of this southern object.
