3M EF200XXL (for 19"-21" monitors)
This is a fantastic monitor filter, but I bought a notebook computer and started using it exclusively, so this just hangs unused above my head on a bookshelf now.
Coatings are purplish and green, on both sides of the glass--like high-end eyepiece coatings. You won't believe the difference in contrast this makes, especially looking at astrophotos. The background sky becomes beautifully dark while objects of interest stand out in rich detail.
Like New. Make me an offer.
Am looking for any FL TeleVue plossl in ANY condition (even bad) and would consider a trade +/- $$ to make it work out.
