..and the 25-50X zoom eyepiece Vortex ? compatible with the Vanguard Endeavor HD 82?
Actually, Optics Planet has a checkout coupon offer right now on the Vanguard Endeavor HD scopes. "Value shipping" is free.
82SCOPE gets $100 off the 82A HD
65SCOPE gets $75 off the 65A and 65S HD
Endeavor 82A HD - $529.99 less $100 coupon less $50 mail-in rebate = $379.99
Endeavor 65A HD - $469.99 less $75 coupon less $50 mail-in rebate = $344.99
Edit: Eitanaltman - Looks while I was writing, you were buying! Glad you found the code.
Poor focus at 60X in a 65mm scope is a sure sign that something is amiss.
