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.
