in the thread on the new 25-60x Kowa zoom, got me thinking: just wondering if anyone on the forum might’ve tried the TE-9Z on the 880/770 series scopes? The TE-9Z (confusingly called the TSE-9Z in a few places on the web) is the zoom eyepiece that gives 20-60x power on the TSN-660 series and 21-63x on the TSN-82SV scopes. Near as I can tell, with the use of the TSN-EC3 adapter,

this eyepiece would give you about 24-73x on the 880/770’s. If the eyepiece gets along with the scopes well enough, this eyepiece& adapter, though expensive, could be a solution for those who own (or who, like myself, are considering buying) one of the 880/770 series scopes and find themselves sometimes wishing for higher magnification than 60x.

This zoom has a pretty narrow field (looks like it would be about a 1.5*-0.85* at these magnifications, similar to what the Nikon MC II zoom gives on the ED82 Fieldscope), so I think I’d not want it as my only eyepiece- but the TE-9z weighs abt. 8 oz, so it wouldn’t be too bad to take with you into the field in case you thought you might need a little more reach on a particular day.

The ep goes for $370-385 new in the US; the adapter, though $90 from Eagle Optics, shows up on Rakuten from Japan here

for abt. $45 USD, which (I think) would end up being $65ish after taking shipping, US taxes into account, still a little cheaper than $90 at EO. So, a lot of $ any way you cut it for the ep + adapter, but still might be worth doing for those really wanting to push the big Kowa a little more (especially perhaps for those of us in the US, where the Swaro ATX 95 is significantly more expensive than the Kowa).

Don't Worry, Be Happy!
I use the now discontinued 21x wide with the adapter on the 883/774 scopes. Useful for big sky views during the raptor migration. Never thought about using the zoom for high powers as my recollection of it on the 663/664 was the optics weren't that good. Thanks for making me think about it again though.

Btw, if you think you might like a good deal on used Kowa kit let me know. I am downsizing mode now and want to sell at least one of my two Kowa's and their digisco kits.
