Galaxy Trios and Triple Systems – Galaxy Trios inspired by Miles Paul’s list and by the Astronomical League Galaxy Groups Observing Club. But there are much more than the two original lists, some very challenging for large telescopes such as my 30" reflector. 240+ trios and triple systems. 8” or larger scope. (288 pages)
Extra: This file also contains a selection of the easiest gravitational lensed quasars, such as the Double Quasar in Ursa Major and Einstein’s cross in Pegasus.
Updated (April 2013): Completed the KTG Catalogue by adding the rest of them, about 14 more. Enhanced a few DSS images and finder charts to reduce clutter and increase clarity.
