I bought these units to compare optics. It's time to sell some of my excessive/compulsiveness so I can start again with OTAs. The Nikons are certainly the best (buy-performers) of the lot. Of course all are used.
The TeleVue comes with 2x OCS. $700
The LOMO has a barlow lens cell that screws into the nose. $235
Siebert's Leather has 2x corrector and 8 Siebert eyepieces. SOLD
The Nikon is the lightest and has the shortest optical path. $325-385
All come with good foamed cases. All in very good-excellent-mint condition. The nikons can be seen on my astrowks site and I will try to get some pics posted soon.
Paypal or checks accepted. Shipping USPS included to US48.
I will answer any questions to my best ability.
