Thanx for that Rob
3C 273 is an awsome object. While you are starring at this object just try to comprehend how far 2 Billion light years away is? and it is moving away from us at 23% the speed of light (I will check that figure).
The Quasar can bee seen from an urban location with a 250mm Dob quite easily and with a 120mm refractor with patience.
A must see object
