This is the worst piece of glass I've ever looked through. So bad I can't even describe it but I'l ltry: flare, significant lack of sharpness, amazing distortion, lack of contrast, just about any and every negative one can think of pertaining to optics.

That being said it looks good and has nice label...

Do an internet search on this, there is one scathing review that I could find that was attached to a long ago CN ad.

Looks to be made from hardware store plastic pipe fittings. The clamping arrangement for a diagonal works pretty well, the best functioning part of the whole thing.

So, if anyone wants to play with this it'll cost you $25 plus shipping. Weighs 3lbs 4oz so no lightweight, total length is 10.5", OD is 4". Shipping from Chico, CA, 95926, box will be about 12x6x6. Fits into a USPS Medium Flat Rate Box.

PayPal preferred but not required, no fee.
