Collimation is a big issue at 150x. I had to send my Saturn III's back to Kevin for alignment before the 150x EP's would work. I know that Kevin probably regrets selling the 150x EP's as it really does require super-good optical alignment for them to provide images that merge reasonably.
But Kevin did a stellar job on my S3's. I have the 5mm EP's marked as I do have to worry about which goes in the left barrel and which in the right (it really does make a difference)! Both BigBinoculars.com and GarrettOptical are splending sites to deal with, both have outstanding support and you cannot go wrong in purchasing from either of them.
150x is a bit too high for binoculars, 90x would be just about right as a top-end. But the 150x EP's DO work - I've seen the CD in Saturn's rings, split the double-double, seen m57 as an obvious "smoke-ring", and caught crater Armstrong on the moon - not the kind of thing you ever expect to do with binoculars.
I'm glad I bought my S3's when I did, and also got the finder (thanks Wayne for prodding me on this!). It's sad they may no longer be offered - they are a wonderful viewing instrument and so lightweight that they get used frequently. I have the 39x EP's with mine and think from time to time about getting the 31x EP's except it's not much of a difference, and since I have the Miyauchi Exceeds(77mm) with the 30x EP's, it's a bit hard to justify the small difference, although I do agree that the wider 2° field is a plus. It's only the thought that these EP's may disappear forever that prods me to reconsider!
BTW - what is the FL of the EP listed on the EP for the 31x EP's? Just curious as I have not seen a pair.... figure it has to be around 23.5mm????
