BST variable polariser eyepice set 1.25"

Recommended Posts

I bought this a while ago and only used it a few times and need to raise some cash for more urgent needs.
There are 2 polarised filters and an adapter. Put one filter on the eyepiece and another on the adapter. Put the adapter into the scope and the eyepiece into the adapter, turn the ep to change the amount of cross polarisation and adjust image brightness.
Good for the moon. 
You can just use one filter as a polariser if you wish or the adapter with other filters - to save having to keep moving the filter between eyepieces.

It looks like there is a tiny chip at the very edge of one of the filters where it fits to the mount that I only noticed when taking the photos - but it doesn't affect it working.
