Celestron 1.25" Blue Eyepiece Filter #80A Jupiter Planetary

Celestron #80A 1.25" Blue Telescope Eyepiece Filter for looking at Jupiter

Brand new but no outer box.  Eyepiece filters are an invaluable aid in lunar and planetary observing.  They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, and lessen eye fatigue.  Celestron's filters are made of high quality, solid plane parallel glass with excellent homogeneity.   The filter cells are anodized aluminum.  The colored filters are anti-reflection coated to prevent glaring and ghosting.  All filters are threaded to fit 1.25" eyepieces.
  Blue filter is great for looking at Jupiter - Enhance the boundaries between the reddish belts and adjacent bright zones. Useful for viewing the Great Red Spot!

Grab this very nice, new - but no box, filter from a trusted eBay store. It comes in a plastic case and is made by a top-brand telescope maker.
