Full Set of 5 RKE Eyepieces and Case

28mm, 21.5mm, 15mm, 12mm, 8mm

The internal configuration of an RKE is essentially the reverse of a Kellner. There is an achromat doublet, a space and then a single element eye lens. The apparent field of view for all these eyepieces is 45 degrees. Eye relief is approximately the same as the focal length. The barrel is aluminum and it is painted flat black in and out. The barrel has the trademark red rubber finger grip. These eyepieces are best on Planets, the Moon, and small deep sky objects like planetary nebula, etc.

Shipping includes full coverage insurance.
