  • Q1: will these moon filters fit on my celestron skymaster 15 x 70 binoculars, and is the polarized style preferred for lunar viewing?

    A: Unfortunately, the Celestron SkyMaster 15x70 binoculars do not take astronomical filters. The Zhumell 25x100 Tachyon is the only binocular currently on the market that takes astronomical filters. The polarized filter cuts glare from the full moon.

  • Q2: Will this eyepiece fit my Celestron Omni 12mm 1-1/4\ eyepiece?"

    A: Absolutely, these are designed to fit on any standard 1 1/4\ eyepiece."

    A: Yes, the Celestron Moon Filter 1-1/4 Inch will fit the Powerseeker 60 EQ.
