Timm: Very good review. I was able to try out the 3mm SPL in a WO 80mm refractor last year, and I think that is its natural habitat, but I only borrowed the scope for a few nights. You've got a lot more detail and information and I was amused that you thought of trying different combinations of top and bottom. I've never thought of doing that.
I'm going to be trying out the 3mm in a 12" f/5 reflector later this year and I have high hopes for it performing well.

Great article Timm. The folks at WO are really putting out a great product. I was thoroughly impressed with a 28 UWAN I once owned.

Thanks everyone - I have bought a WO Zoom II that I hope to test if Spring ever shows up here in the Midwest.

Nice review Timm. I found your discovery of switching the barrels the most interesting!

Nicely done. Really like how you used different parts of each one to make new versions. Would be worth it to buy an extra set just to make up the in-between sizes. BTW, have you noticed that they seem to be the exact same eyepieces sold by Smart Astronomy and Orion, but that theirs are only $100.00?

Hi Timm,

I appreciated your review of these eyepieces. It was well written and interesting.

I think that the review could have been more informative, if the comparisons had been with other typically standard planetary eyepieces, however. In other words, a direct comparison between the SPL's and good orthos and plossls would have been more helpful to me. I am interested in how well the SPL's compare in contrast, light-scatter and on axis sharpness to TV Plossls, for example. It didn't really surprise me that the SPL's could perform better on the planets than the UWA's or the Nagler.

Thank you again for your review!

Clear Skies,

Clear Skies,




Thanks Ed,

It comes down to economics. I wish I had some other eyepieces you mentioned to compare to, but as I said, I got rid of the plossls and orthos because I needed the money to fund the UWANs at the time, and sold them.

I think the best comparisons to make would be with ANY other eyepieces that have this level of comfortable viewing, like a TV Radian, but I don't have those either.

If you have high quality orthos or plossls that you like, that can get you to the magnification you need, either with or without a barlow, and you find them comfortable to view through, then I think you should stick with them.

Thanks,

Timm

Yes - I see that both are offering up what looks like the same eyepieces now for a lower price. That's great! Competition is a good thing. Maybe WO will lower their prices too if they feel like they need to. I am guessing that Long Perng in Taiwan is the OEM for these, since they appear now on their webite as well

If you want a great little scope, search out the red anniversary WO ZS80 Flourite Doublet on the used market... the flourite glass in this little scope impresses me each time I use it. The Megrez 90 is using a better quaility glass than the ZS80 ED you are looking at so that is why the price difference. I do agree with your reasons for looking at the ZS80... I too will pull out the bigger light catcher when I have the time and strength.
