Hi Julian
I use a gso neutral density (nd) 96 0.9
That cuts down the glare a lot and I think it was only $20 deliverd
Or you can stop down your scope with cardboard take it from say 6in down to 3in or 2in won't lose res but. Cuts glare

Hi Julian,

If you read my article on "Visual Astronomy and the use of filters" it explains the difference between neutral density (moon) filters and variable polarising filters.

http://www.iceinspace.com.au/63-680-0-0-1-0.html

In my opinion the Variable Polarising filter from Orion or Lumicon is easily the best option. It gives variable rates of blockout from 5% to 35% which is user adjustable. You may want to vary the degree of blockout depending on scope aperture, eyepiece and moon phase.

You need to make sure you get the "variable" polariser not the single polariser.

Cheers,
John B
