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.

Dbl: H177 AB, RA 11:02:06, Dec -15:41:32, Mag1 8.6, Mag2 8.9, Sep 2.9".
2015-04-21, C11, 13mm Hyperion, 215x, Rating 4. Attractive pair of deep golden stars, mildly unequal and close at 215x.

Dbl: A132 AB, RA 10:53:19, Dec -10:45:12, Mag1 8.9, Mag2 9.6, Sep 4.4".
2015-04-21, C11, 13mm Hyperion, 215x, Rating 3. Faint, mildly unequal, yellow, white pair, nicely split at 215x.

Dbl: A1770 AB,C, RA 10:57:31, Dec -11:05:21, Mag1 8.6, Mag2 9.4, Sep 4.5".
2015-04-21, C11, 13mm Hyperion, 215x, Rating 3. Mildly unequal yellow suns, nicely separated at 215x.

Dbl: STF1509 AB, RA 11:06:30, Dec -13:25:03, Mag1 7.4, Mag2 9.4, Sep 33.2".
2015-04-21, C11, 55mm TV Plossl, 51x, Rating 3. Golden orange primary, well separated from a fainter, paler secondary at 50x.

Dbl: STF1530 AB, RA 11:19:44, Dec -06:53:55, Mag1 8.6, Mag2 8.9, Sep 7.7".
2015-04-21, C11, 55mm TV Plossl, 51x, Rating 3. Almost identical yellow stars, lovely and close at 50x.

Dbl: Crt, 15 Crt AB, RA 11:24:53, Dec -17:41:03, Mag1 4.1, Mag2 7.9, Sep 5.3".
2015-04-21, C11, 13mm Hyperion, 215x, Rating 3. Brilliant white star, nicely separated from a much fainter yellowish companion at 215x. The WDS data are misleading, the secondary is actually magnitude 9 to 10.

Dbl: HJ4479 AB, RA 11:53:20, Dec -24:35:15, Mag1 8.9, Mag2 9.9, Sep 7.5".
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.

Hi
Thanks for the observation report
Do you get these details from your GOTO mount catalogue or from stalarium ?

Thanks

Hi,

I use a programme called AstroPlanner to compile lists of objects in advance, and to control the mount and record my notes during observation sessions. AstroPlanner includes a large number of catalogues from which possible targets can be selected, and I use the Washington Double Star (WDS) catalogue to get the data for double stars. I'd be happy to give more details if you are interested.

Mike
