Should be an easy double but had a little trouble splitting it because they appeared a little dimm because of a little haze there. Splitted but no colors detected.
 
Ambience: After a long period of cloudy nights, had a oportunity to start Corvus project. Sky conditions where not as good as I desired, but I was hopeless for an even so so observing night and that was what I had. Some clouds, some moisture and some haze.

Despite of all that, I took my car and went to "Tijuca´s National Forest Park", anti-bug lotion in hands and wishes to see as many doubles as possible...

This fine double forms a neat triangle with Alpha and Epsilon Corvi. This is a faint, delicate pair whose Light Blue and Rose pastel colours seem to shimmer together
because of their closeness. Just separated at medium power but best seen at about X144. HS 2.
