Very nice accessory as reviewed on Cloudy Nights. This one is set up to take your choice of either five .965" eyepieces or one 1.25" one and four .965" eyepieces using Takahashi compression ring fittings.
All adapters interchange so you can use various combinations including the large Takahashi screw in eyepieces like the 32mm Erfle or 40mm Ortho. This would be great for a Lunar or Planetary observer with a set of Tak or Pentax orthos. Nice for quick looks especially this winter when you can load the turret indoors and have any of five available with a simple turn of the turret without bringing all your eyepiece cases out with you. Fits any Tak scope. Excellent condition.
