This is a wonderful well made eyepiece with 12mm of eye relief and a 75 degree FOV. I am however in love with the Meade 14mm UWA and must return to it. I have tried other eyepieces, but always come back to the Meade 14mm. This eyepiece comes with bolt case and bottom cap. Optics are pristine. PayPal(add 3%) or money order.
