Site classification: Rural
Sky darkness: 6.0 <Limiting magnitude>
Seeing:
Moon presence: None - moon not in sky / Minor - crescent or far from object
Instrument: 4.5" Homemade Dobson reflector, f/8 ("babydob")
Magnification: 25x, 48x, 79x, 96x, 140x
Filter(s): None
Object(s): 2 Sco, 3 Sco
Category: Multiple star
Class:
Constellation: Sco
Data: mag 4.6, 4.7, 5.8, 6.1  size 3", 1.5"
Position:
Description:
2 Sco is 3" pair of 4.6 and 4.7 mag stars.
3 Sco is 1.5" pair of 5.8 and 6.1 mag stars.
Those 2 pairs are separated just 15" and they could fit into a single 
FOV at 150x to 200x. That power should be enough to separate both pairs.

Unfortunately, I couldn't resolve neither star at any magnification I 
tried (25x, 48x, 79x, 96x and 140x)

Maybe data in Skymap are wrong?
