Telescope Manual

Old Style Celestron NexStar GPS mount with Celestron C-8 Starbright coating

Included in this package:

  • Mount: Celestron NexStar GPS Dual Fork Mount

  • Heavy Duty Tripod

  • C-8 Optical Tube Assembly (OTA) with StarBright coating (8" Aperture)

  • Starizona Landing Pad

  • 50mm Finder Scope

  • Starpointer Pro Finder Scope

  • Star Diagonal

  • 25mm Kellner eyepiece

  • 9mm Plossl eyepiece

  • Power Supply (120v -> 12V)

  • 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

Images: 1, 2, 3 5

 

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.

Celestron StarSense Explorer DX 130AZ

$250

$480

Additional Images: 1, 2, 3, 4, 5, 6

This unit is in near new condition.  This is a great beginner telescope reasonably priced and with your smart phone added to the system you have a push-to system where directional arrows on the telephone application show you where to point your telescope.  This makes locating objects much easier than other methods like star-hopping.  The learning curve on this telescope is probably the best of all beginner telescopes.  I highly recommend this scope for someone who wants to experiment with astronomy, but not ready to shell out thousands for a higher end telescope.

This unit is in near new condition with a couple of exceptions.  First the original counter weight seems to have gone missing, so I have adapted one from another telescope for this one.  Second the accessories tray has a flake of plastic missing, not an issue as far as function goes.
