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. For more detail you can refer to my report at by clicking the following link:

This two component air-divided ED APO binocular is made for high power use. Utilizing Chengdu CDGM FK61 glass and a huge opening of 100 mm, you are enabled to view up to and past 100X easily. This binocular is a genuine APO, offering eminent shading interpretation and a significant level of round remedy.
These monster binoculars accompany a lot of 20mm eyepieces with a wide 70° field of view, for an amplification of 27.5X. It is anything but difficult to change out these eyepieces when you need to see at various amplifications.
The binoculars acknowledge standard 1.25" eyepieces, which are situated in helical focusers that use metal pressure rings to keep up a firmly focused view. The binocular mount permits the connection of most dovetails, and a convey handle is incorporated to make it simple to move and set-up.
