Crater is a rather modest constellation, with no really bright stars and few deep sky objects. It's tally of doubles is rather poor too, I checked 20 or so in which the primary is at least magnitude 9 and the secondary at least magnitude 10, and only the following were particularly noteworthy. Thanks for reading, Mike.

2015-04-21, C11, 55mm TV Plossl, 51x, Rating 3. Mildly unequal stars, very close at 50x, forming a right angle triangle with neighbouring field stars. Low, and viewed through bushes, so couldn't judge the colours.
