Have used this Easy guider about a dozen times on my 16" Newtonian.
It's in great condition, no scratches on the Prism.
Everything else is fine, except maybe a few fingerprints on the metal.
All thumbscrews in place.
Adjustable 360 degree rotation, and the EP holder adjust radially, for centering star.
Worked great with Lumcon's 3x Diagonal relay, which I am keeping.
I don't remember it costing $189, been about 6 years, but that's what Lumicon gets for these new.
I was hoping for a trade, NGF DX3 focuser, preferrably with backing plates "10" radius (19" OTA)
Asking $90 Money order or Paypal.
Will pay shipping to lower 48 states only
