On the 10th October 1996 the Lassell Telescope. was officially opened at the Triton 150th Anniversary celebrations, held at St Michael's School, the original site for the telescope at "Starfields", by Patrick Moore.

It was on this day 150 years ago that William Lassell first saw a point of light next to the newly discovered planet "Le Verrier", or Neptune as it was to be later known, Lassell thought it was satellite, but it took many months before this could be confirmed. This satellite was to be named Triton.

The evenings celebrations continued with a buffet, followed by a talk on William Lassell by Dr Allan Chapman. The evening was rounded off by a brief drama activity starring William Lassell (Mr B.Hallet). Attending the celebrations were some 20 descendants of William Lassell, brought together for this occasion with the help of Gerard Gilligan of the Liverpool Astronomical Society.
