The 6-Element Erfle has a renowned reputation for providing wide, expansive, flat-field images. If your telescope has a 2" focuser, these eyepieces will deliver crisp, high contrast and stunningly wide views of the heavens. Standard features include 2" barrels threaded for standard filters, fully multi-coated design, edge blackened lenses, rubber grips and fold-down rubber eyeshield. All models have luxurious eye relief. If you have a high F-ratio scope, the Erfle 32mm is also available with 70 degrees AFOV. If that isn't enough, get the 8-element Modified Erfle 30mm: just about the widest view possible with the 2" format. We also include a free bolt case with each eyepiece you purchase.
