Group Description

This is a place to discuss using, choosing, modifying, accesorizing, building
and observing with big dobsonian telescopes.

This group
welcomes discussions of what is unique to using big
dobs of any make.

Oh, yeah. We also get to discuss
what "big" means.


Polite comparisons of features, performace, usability and seviceablity of big dobs from different manufacturers is specifically *NOT* forbidden. (Note that some brand-specific telescope groups discourage such comparisons. This group does not.)

All postings must be civil. Off topic postings must
be humorous, friendly and rare. This group is retro-moderated. Off topic posters will be moderated or deleted. Please read the
policy.
