Harvey has been around for many years.  This high resolution telescope is quick to set up and simple to use.  It has little chromatic aberration, and the quality of its field of view is quite comparable to the larger 8” reflectors in the telescope library.  It provides nice views of nebulas, planets, and the moon.  It lacks sufficient power for viewing smaller deep sky objects.  

It is rather tall, and the tube is quite sturdily constructed.  Unfortunately the one-arm Dobsonian mount is a lot shakier than ideal, and has a tendency to spring back when pointing the scope.  Like all reflectors it can be somewhat counter-intuitive when trying to center the view on an object. 

Comes with a deep sky filter for nebulae and galaxies.
