Large Format Binos by Lunt EngineeringLunt Engineering now offers big apochromatic binoculars — really big. The Lunt Engineering 100 mm ED APO Large Format Binoculars (starting at $2,950) are designed for seri- ous observing with both eyes open. These premium 4-inch binocu- lars are built around two-element, air-spaced ED glass objectives, providing superb color correction. Its multi-coated roof prisms fully illuminate the field of view. The eyepieces are seated at a comfort- able 45° viewing angle with an adjustable interpupillary distance range of 54 to 75 mm. The unit also accepts most 11⁄4-inch eyepieces seated in helical focusers, with non-marring brass compression rings in collet-style locking mechanisms. Weighing 14.52 lb (6.59 kg), the binoculars include a sturdy tripod mounting bracket, heavy- duty carry handle, and a unit-power finder to quickly and accurately aim at your chosen targets in the sky. Each purchase includes a matched pair of 20-mm eyepieces.

    I am considering the Lunt Engineering 100mm binoculars as a more spontaneous and portable astronomy outreach as opposed to my 12″ Meade that I can no longer lift onto the mount. If anyone has a pair of these binoculars, I would love to know what you think about them. Are the views of Saturn, Jupiter and the moon satisfying and inspire a WOW? What about star clusters and doubles? What mount is recommended? Is iPhone photography possible?

    Maybe you bought the binos already? If not, I can confirm the WOW-effect, which is strongest observing star fields and open star clusters. These binos shine primarily when used for extended objects. Smaller ones, such as the planets, are less satisfactory. The focal length is just too short for high magnifications. But looking at the milky way with dark skies is absolutely overwhelming, especially in the southern hemisphere.
    For mounting the binoculars there are many options. After intense research I settled on a LIBEC fluid head and tripod, the LIBEC LX7M. The head including the fluid head and the tripod cost around 500 $US. The counter weight is fixed, i.e. not adjustable, but perfect for the Lunt/APM 100mm ED-APOs, so adjustment is actually not needed. Compared to other fluid heads and tripods of similar quality, the LIBEC is a steal to my opinion. Rock solid and smooth balanced movement of the binos. The max payload is 8kg, so just right for the binos and a pair of eyepieces.
