Apertura 1.25" Moon Filter

The Moon is bright and this Moon Filter is just the thing for more comfortable (and rewarding!) viewing. It's like putting sunglasses on your telescope eyepiece! To use the Apertura Moon Filter, simply thread onto the barrel of a 1.25" eyepiece or Barlow lens with M28.5 x 0.6 thread and then insert into the focuser or diagonal as usual. You will be amazed at how lunar features, such as craters big and small, maria, and mountains come into view when your eyes are not overpowered by the moon's brightness. This Apertura Moon Filter works well for Venus as well!

The Apertura 1.25" moon filter has been produced with high-grade optical glass and is anti-reflection coated to prevent glaring and ghosting. The green tint of the filter, along with 18% light transmission allows detailed views with increased contrast. For the price, you can't beat this filter as it should be a staple in any astronomy filter collection. A plastic storage case is included.
