    What’s about Reviews of the NL 10x32

    I have the same issue with the 10x32s, but not with the 8x42s. It's not too severe and will look for some o-rings to move the eyecups out 1-2mm.

    NL Focus Wheel Problems After Washing

    I'm a NL Pure fanboy. However these focus wheel failures are rather troubling. The reason I got into Alpha optics was their waterproofness and durability. After hearing a few stories about bins fogging up and failing on tropical tours I bought my first Alphas, Leica 8x32 BAs, for my first...

    Guyana: Jewel of the Guianan Shield

    Sound like a fantastic trip! Guyana is a special place. Did it a couple times years ago just as it was becoming known as a birding destination. Your list is a fair bit better than what we had.

    Any customer review of new tsn-99?

    I'm sorta wishing I kept the 883 I had a year ago. I may try replacing my ATX 95mm module with an 85mm and repurchasing the 1.7x extender. It would be more appropriate on my 128RC head. The ATX eyepiece diameter is still too large for my taste, but the panning dampening of the 128RC is better...

    Any customer review of new tsn-99?

    After further review I'll be returning the 2nd copy. The ST inner results appeared very good with perhaps slight astigmatism. The outer focus view had a larger center disc and a dimmer outer ring. Performance was pretty good up to 50x-60x, but deteriorated at 70x, especially compared to my S2...

    Any customer review of new tsn-99?

    The 2nd copy I received a few days ago is better than the 1st. The STP (Star Test Pattern) is similar to Henry's 2nd copy. Apparent resolution seems to be equal to my ATX95. Contrast might be a touch less. Hope to try it out on some actual birds in the next few days once it warms up a bit...

    Kowa vs Swarovski

    I agree with pretty much all of the assessments in this thread of the various pros and cons of the most recent Kowa and Swaro scopes. A couple new topics: 1. With the 77 You could be giving up a fair amount of brightness under dim conditions. Anecdotally the ATXs seem to hit above their...

    The outside focus in Henry's focus looks like that in the copy I had.

    Any customer review of new tsn-99?

    The ATX eyecup is 58mm, the housing adds another 10mm. The Kowa is a bit more than I like but I found it much better than the ATX. The S2 is only 47mm.

    Any customer review of new tsn-99?

    I had one Kimmo and sold it as I intended to sell the ATX95. It did work very well, but found it cumbersome to swap in and out (as well as remember to have it on me.) May give the ATX95 another go around this spring to see if I can get over the eyepiece diameter issue. I thought using the 99A...
