This is a great-working, 1990 Celestron 8x20 straight through finder scope with both its original caps. It will come in its original black, cast aluminum finder bracket, it will has all (3) original steel-with-nylon-tipped set screws and the original rubber o-ring.

The finder is a true doublet fully coated system and housed in a solid milled aluminum and brass body with a rubber eye guard. The cross hair setup in these finders is my favorite of all time in small finders as they are extremely easy to see even in the dark; check out the last photo.
Images given are correct as the eyepiece-end has a small prism assembly that fixes the upside down issue.

The finder brackets are solid cast aluminum and durably built. The set screws are steel and will house any 20mm to 24mm aperture finder marketed by Meade, Celestron, or Orion; possibly Tasco as well, but not Unitron. So if you have an orange C90 5x24 finder OR the black gloss C4.5 5x24 finder, it will fit in these rings. With this setup utilizing the o-ring, this finder WILL NOT lose alignment to the scope it serves.

The elongated, stock cuts on the bracket shoe will allow it to immediately fit to ANY YEARS C90 or C5 from the USA. It should have no issues mounting to the Meade 97 Series of the same years. The spread on this shoe is 1.08-inches where it will mount to the optical tube.

Weighs exactly 3.5 ounces

Cosmetics are mint on the cast brackets, excellent on the screws, the finder body is excellent, the eye guard very excellent, eyepiece cap very excellent, lens cap good (has a crack), objective is great, maybe excellent with some minor swirls, but no fungus, dust issues, or pitting, the eyepiece optics are great; clear crisp images, but there is coating loss, and the cross hairs are mint.

Price doesn't include shipping. Will ship to anyone on Earth.
