Thanks for the comments guys, may even have another go tonight. One of these days I 'll catch Aristarchus in good seeing with the perfect illumination angle, tonight could be the night.
Just as an aside, did some eyeballing outside about an hour ago and manged to see 6 planets, needed binos' for 1 of them. Mercury and Mars are in conjunction low in the west with Venus high above them. Turn around to face East and there is Saturn and Jupiter and look down and there is the Earth.
Followed by a pass of the ISS at mag -3.1 and during which it skimmed past Omega Centauri . Nice little evenings entertainment.
