(SOLD) 60mm x F16 telescope with Calcium Skybender

Post by TheSkyBurner » Tue Oct 30, 2018 4:27 am

up for grabs is my incredibly rare 60mm x 1000mm (f/16) vintage scope. It is very well corrected at 393.4nm . The scope is 50+ years old and is in great condition for its age. I replaced the focuser to a modern 2" The objective lens could use a single wipe (it is 100% scratch free and never touched).

There is an Internal 36mm baader planetarium B-ccd ERF filter mounted inside the ota, placed before the focuser. This is mounted in a 37mm threaded optical cell. The optical cell is Threaded onto a slip fit 58mm extension that is screwed into the ota sct focuser flange. It is very easily removable, and it slides right out after the three screws are removed.)

1.25" Black Skybender with 1.25" 2.4 angstrom calcium K-line filter.
The scope has a rotatable GSO 2" crayford focuser and GSO tube rings

Works right out of the box!

The calcium filter has a coating defect on the anti-reflection side. I have posted images of it. I have tested the filter today and it performs flawlessly!

The coating defect is only on the anti-reflection part of the filter on the clear side, it is guaranteed by me to have zero affect on the the actual performance or image quality of this filter. I fully tested it today 10-29-2018. I will provide you with more images if you want with them.

I tried to get the filter replaced via warranty this week, but unfortunate the warranty is expired. I am the original owner (original cost was $1200.00, filter is 1.5 years old)

Attached 40 frame raw video samples of the calcium filter in real time operation to show that it indeed still provides a very crisp focused image. The dust spots are not permanent!I am just terrible at cleaning my optics. I live in a forrest.

Asking $650.00, price including priority 7 day international shipping.
