These images are shown on monitors in each observatory as well as in the HotSpot Classroom.

This is an excellent scope for deep sky objects as well as planetary viewing. The largest refracting telescope at the observatory is also on this platform. The StellarVue 152 is exceptional at viewing planets, stars, and clusters. The scope can also be fi tted with a solar fi lter for viewing the sun and sunspots. The TeleVue 102 telescope is dedicated to solar viewing. This scope is fi tted with a Coronado H-Alpha solar fi lter for observ- ing solar prominences and granulation. The HotSpot Classroom provides a building to conduct educational presentations and classes. It can also be a warming room for guests to relax More STAR GAZING on Pg 14 Connections July/August 2019 13
