Moon presence: None - moon not in sky
Instrument: 4.5" Homemade Dobson reflector, f/8 ("babydob")
Magnification: 25x, 48x, 79x
Filter(s): None

Category: Open cluster
Class:
Constellation: Sct
Data: mag 8.9 size 6'
Position:
Description:
25x: I see just the brightest (9.7-mag) star.
48x, 79x: The same, even with averted vision.
Later at home, I checked data on this cluster and I found out that there
are just 3 more stars brighter than mag of 12, and most of the others
are between mags 14 and 15. I guess this is not a cluster for my 4.5"
babydob.
The cluster was 28 deg above the horizon.
