I am getting a decent sized Dob made by Peter Read, SDM Telescopes, VIC, Australia. 28" f/3.3. I will be using it some of the time to show school students and parents the Moon and Planets. This telescope will have a pretty strong light grasp. Do I need to get a Polarising Filter to cut down the light when showing them the Moon?

I would really appreciate hearing back for anyone who has biggish Dob.

I will post photos when the scope arrives.

Thanks
