Observing Notes

Andrew Cooper
30 Dec 2015 Waikoloa, HI (map)
28cm f/10 SCT, NexStar 11" Gypsy @ 233x

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

Andrew Cooper
1 Mar 2011 Hale Pohaku, HI (map)
46cm f/4.5 Newtonian, Deep Violet @ 175x

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

Andrew Cooper
3 Dec 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
20 Mar 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

Rev. T.W. Webb
Hardwick, Herefordshire, England (map)
24cm Reflector

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.
