Very useful for planets and deep sky objects. Extremely sharp images from edge to edge. Higher contrast than other similarly sharp eyepieces, which I especially like when viewing faint galaxies and nebulae. Very high contrast is what sold me on Pentax SMC-XW eyepieces. I also use the SMC-XW 20 mm eyepiece for the same purposes. Thank you Pentax!!
Great eye piece at a great price!
I am very happy with this purchase.The twist up eyeguard is a big improvement over the traditional rubber type.All six of the 1 1/4 eyepieces are parfocal(almost no refocusing).There is a generous 20mm of eye relief.The optics produce excellent views, even in a short focal length scope.
