Observing Notes

Andrew Cooper
Sep 12, 2020    Waikoloa, HI (map)
20cm f/6 Newtonian, Cave Astrola @ 135x
Seeing: 5 Transparency: 7 Moon: 0%

A small equilateral triangle of three faint 10-12th magnitude stars about 1' across, a fourth fainter 12th magnitude star just off the western corner, a little over 1° east of M73

28cm f/10 SCT, NexStar 11" GyPSy @ 127x
Seeing: 7 Transparency: 7 Moon: 0%

A small trio of stars 10-12th magnitude in a neat equilateral triangle 1' on a side, one additional 12th magnitude star off the northwest corner

28cm f/10 SCT, NexStar 11" GyPSy @ 127x
Seeing: 7 Transparency: 7 Moon: 0%

A small asterism of four stars roughly in a triangle, quite distinct and curious

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

An odd group of four stars in a 'Y' pattern, it would take poor optics indeed to mistake this for a proper DSO

Apr 18, 2010    Hale Pohaku, HI (map)
46cm f/4.5 Newtonian, Deep Violet @ 175x
Seeing: 6 Transparency: 7 Moon: 0%

A small group of four dim stars ranging from 10th to 13th magnitude, three stars are arranged in an equilateral triangle with the fourth star in the center, a poor object but one could understand how it could be seen as a nebulae with inferior optics

Sep 5, 2008    Hale Pohaku, HI (map)
28cm f/10 SCT Gypsy @ 233x
Seeing: 6 Transparency: 7.5 Moon: 0%

A group of four stars, nearly matched brightness, three arranged in an equilateral triangle, the remaining star just to the side, in the telescope this is a very plain object, M72 is 1°20' west

12x36 Canon Image Stabilized Binoculars

A tight group of a few stars, less than on field (1°20') east of M72, small, resolved, like M29 an object that looks more interesting at low power, one can understand why Messier included it in his list

20cm f/10 SCT

I agree with Smyth in that it is a poor object, the dimmest star at magnitude 12.0 is just on the edge of visibility tonight, must use averted vision

Charles Messier
Oct 4, 1780    

Cluster of three or four small stars, which resembles a nebula at first sight, containing a little nebulosity: this cluster is situated on the same parallel as the preceding nebula [M72]: its position was determined from the same star Nu Aquarii."
