The Celestron Regal 65 F-ED Spotting Scope is a fully waterproof, armored device accepting any conventional 1.25" astronomy eyepiece, delivered with a zoom ocular. Celestron's been making premium scopes for awhile now, and the Regal F shows much in the way of evolution: the sunshade hood now telescopes and has a rotating sighting aid, the tripod collar now rotates as well, and they made the eyepieces interchangeable. The supplied eyepiece also features a T-threading just under the eyeguard; merely add a T-mount for your SLR camera to digiscope directly through the eyepiece.
But the Regal 65 F-ED's best improvement is that one of the objective elements now contains fluorite, a costly crystal material which goes a long way towards achieving true apochromatic color correction. Whenever light's harsh and contrasty, or when a colorful bird is cast against an overwhelming drab gray background, the fluorite will help define those edges of subject and background like no other element can.
For their flagship Regals, Celestron chose to only produce angled scopes. Angled scopes are much easier to share amongst a group of observers and are generally regarded as giving a more relaxed, comfortable observing position unless you're elevated more than 45° above a subject. It takes some experience to quickly locate subjects.
The Regal 65 F-ED's 65mm diameter objective lens is the practical choice for many seasoned observers, providing a good compromise between brightness and compact dimensions. Paired together with a decent carbon fiber tripod, or perhaps a "trunnion shaft" tripod, and you'll have an outfit weighing below 8 pounds-easily taken upon even the most ardent of nature treks.
Celestron's Regal spotting scopes include their wonderful "No Fault" warranty coverage, which assures that your scope will be repaired or replaced at Celestron's option for as long as you own them-no questions asked! The only requirements on the user's end are to ship the binoculars (at the user's cost) to Celestron with a proof of purchase and a check or money order for $25 to cover the costs of inspection, shipping and handling. This warranty service is valid only for USA and Canadian citizens.
