Went specifically after Messiers this time around.. any NGC objects
are coincidental. Will take a look at this in two parts. This is part 1.
M60- In same field as NGC4647, 4638, and M59. I may be a bit
confused here..as to which was which, verified my drawing to others.
M60 was large and elliptical, bland. Just a brief peak.
NGC4647 just NW of M60 & stretched out, nearly perpendicularly
to M60 and looked more like a spiral . It was very close to M60..
nearly touching.
M59 was a smaller elliptical off to the west, in the same field but
clear on the other end, at 71X. Like an M60 junior. Both very easy.
NGC4638 was much like M59, a smaller, round or slightly elliptical
bland nothing, not as bright and south of M59
(I give the four above a rating of "B" when considered in concert)
M58 was elliptical in shape, with a starlike (broad star, not sharp
like M90) nucleus. Nice foreground star, NW C+
M87 was large, round and bluish in color, with a nice foreground star,
West, looking much (very much) like an unresolved globular B-
NGC4550, 4551 are two little twins (although one is listed as edge-on
and one not) they both looked edge-on to me, and formed a "V". Tiny
cuties: Rating: B Ran into these by mistake, on my way to
M89 which I talk about in Part 2. Only had only a brief peak, not
close scrutiny.
thanks!
