Level
Carry Case for Optical Tube Assembly (OTA)
Observations: Tested telescope and after alignment GOT works quite nice
Condition: Telescope is in good condition with minor scratches that will not impact functionality. Optical system is in good condition and are collimated. Did not get a chance to verify GPS is working on mount. This is a very heavy mount compared to most GOTO systems, but the dual fork should add stablility to the OTA.
Comments: Bolts used to secure
mount to tripod are not original but work fine. Also
Optical Tube Assembly (OTA) is not part of the original mount system,
but works fine. Updated
Mount and control pad Firmware to latest version.

Meade 8" SCT

N/A
Classic Mead SCT on Equatorial Fork Mount.
I did check the clock drive, and it appears to work fine (you will need to supply a 12V power supply).
Basically what you are getting with this package is a 8" SCT on an equatorial Fork with clock drive and 8x50 finderscope.. Hard to beat this price. A great scope for visual observation and capable of supporting planetary imaging.
Also included (for free) visual back, Star Diagonal and 22-7mm zoom eyepiece. It should be noted the Star Diagonal and Zoom eyepiece are of low quality and should be replaced ASAP.
