Description

For the lovers of Newtonian Reflector telescopes!

This is the official replacement group for NewtonianReflectors, which was killed by a troublemaker/hacker.

The original NewtonianReflectors group was owned by Dave Scott and moderated by Christopher Erickson.

All questions and comments about Newtonian reflecting telescopes are encouraged here.

But please, no spam, flames, politics or religion! Solicitations to join other groups need to be pre-approved by the group moderators.

Welcome!
