Observing Notes

Andrew Cooper

28cm f/10 SCT, NexStar 11" Gypsy @ 233x
Seeing: 6 Transparency: 6 Moon: 0%

A beautiful cluster of innumerable faint stars in a distinct 5' area, resolved, very rich, in a dense Milky Way starfield

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

At low magnification a faint unresolved patch, with more magnification it resolves into a very rich cluster of faint stars about 5' across, quite the contrast to M35 seen 30' northwest

Dec 3, 2004    Sentinel, AZ (map)
46cm f/4.5 Deep Violet

Very rich! dim, just resolved into innumerable stars with slightly higher power, fan shaped with a field of brighter stars for contrast, M35 is just outside the field 23' to the northeast, a line of slightly brighter stars on the west side, rich star field surrounds

Andrew Cooper
Mar 20, 2004    Farnsworth Ranch, Pima Co., AZ (map)
28cm f/10 SCT Nexstar 11

Beautiful cluster in the margin of M35, a chain of brighter stars leads south from the large cluster to 2158, compact, rich, dim, dozens of stars barely resolved in a 5' patch

About 1/2° sp,[of M35] just beyond a group of outliers, is NGC2158 (H. VI 17), a faint dim cloud of very minute stars.
