what is the difference between the 20 x 80 Celestron binoculars and the 20 x 80 "Pro" binoculars?

saw an interview where the product manager said the prisms are bigger in the Pro. Saw a comment that the prism of the regular, non-pro only handles about 63mm of the objective lens throughput. So Pro much brighter than the standard. Also pro has twist-up eyecups. Downside of Pro is only 15.5mm eye releif vs. 18mm with the standard 20x80. Another downside is the field of view is reduced to 155' compared to 195 ft. at 1000 yards. As a glasses wearer, 15.5 is not long enough.

Why are there no pockets on the carrying case? No place to put the extra eyecups, lens cloth, or red dot rail!

I often wonder why not all dresses have pockets either. Probably the same reason airlines stopped serving meals.

I'd like to make sure i'll be able to look at the sun before i buy these binos. any tailor-made sun filters for this model? if not,any suggestions?tks

You’ll have to search for any purpose made filters. Lacking those, if you have a solar filter for a telescope, mine for an 8” Celestron C8, you can create a homemade mount to hold that filter in front if the binos.
