Description:
NGC 3440: This 13,1magv galaxy appears as a very faint NE-SW elongated streak 
of light without other detail. Difficult at 131x.
NGC3445: 12,2magv. 10’ SE of 3340 and only 1,5’ from a brilliant 10mag star. At 
131x NGC 3345 shows a faint non-stellar core and a halo slightly elongated N-S 
(1x1,5’).
NGC3458: 12,1magv. 14’ NE of 3445 this small galaxy features a bright stellar 
nucleus surrounded by a faint, small halo extending only about 1’. The halo 
appears to be almost round.
All 3 galaxies are beautifully located within the FOV at 131x magnification. 
Very nice group.
