For Sale: 8″ Celestron SCT with Extras — SOLD

SOLD, the OTA at least. Finder, dew shield, and solar filter are still available.

Looking to upgrade your 5 or 6 inch SCT to an 8?  For Sale one 8″ Celestron SCT. Not sure of age but probably manufactured between 2000 & 2005. Optics have Starbright Coatings and the scope is Fastar capabable. I have used this scope with a borrowed Faster adapter and imaged successfully at f/2. The scope is used and has the nicks that come with use but the scope still performs well and I am selling only because I got the fever and replaced it with a C9.25 recently. I’ve tried to include some of the nicks in the pictures so you’ll see what you are getting. The scope retains collimation well and has collimation knobs. The pictures include two shots of Jupiter that I recently took with this scope to show what it is capable of.
Included are: The scope itself with a visual back, collimation knobs, front and back dust caps,  a CG-5 dovetail bar, a 50mm 7x finder and bracket, a white light glass solar filter, and a hard plastic dew shield.
Asking $450 plus shipping if needed. I will want to pay extra to the carrier to package everything so that they will guarantee safe delivery.

For Sale: Celestron Advanced Series GT German Equatorial Mount – SOLD


I’ve owned and used this mount for about 9 years now.  It has been a solid performer.  I still use it but am looking to upgrade to a mount that can carry a heavier load for astrophotography. The ASGT is officially capable of up to 30 lbs but that payload would be visual only. I’ve had an 8″ SCT with smallish guide scope, total of 20 lbs successfully. Celestron used to sell this with various OTA configurations including 5″ to 11″ SCT, 8″ to 10″ Newts and up to 6″ refractors.  This ASGT has very good GOTO capabilities, once you’ve gone through the alignment process it can find what you want with ease.  The hand controller has, I believe, 13,000 objects in its database. When I had a  camera with a 0.4 degree FOV attached and good alignment done the object would be in the view on the first try.  The periodic error is a limiting factor, I had to limit exposures to about 5 minutes and throw out a third due to the blip when I was imaging.  However, if you are not imaging or doing short exposures that won’t be a problem. The power switch started developing a problem a couple years back and, not being incredibly electronically skilled, I sealed the switch in the on position with silicone sealant. See the picture below.  The switch is probably easy to repair if you know how.  Other than this, the mount has the scratches you would expect from a mount this age but is in good shape.  Selling the items below for $450 with central Arkansas delivery or pickup.  Will be happy to assemble mount and demo it for you.  If interested, contact me at jamesdixonlr at or 501-258-1914.  Will deliver to central Arkansas or meet you halfway farther out in Arkansas.

The mount includes the following:

  • The mount itself.
  • A Nexstar hand controller.
  • Auxilliary port that allows you to connect your laptop among other things to the telescope. I’ve used this and planetarium software to drive the scope.
  • Tripod leg spreader.
  • 11 lbs counterweight.
  • Both an AC and 12 volt DC power cord.

For Sale: Orion StarBlast 4.5″ Dobsonian — SOLD!!!

Sold in 9 hours!  Thanks, Jeff!

I bought this years ago for the kids. They are mostly grown now and the scope is sitting idle in the garage. It is an f/4 113 mm diameter scope. It is a table top dob although I used a hand crafted wooden mount that was built for my fork mounted SCT when I had that. Many scopes like this have a simple spherical objective but this one has a true parabolic mirror that provides great wide angle views. It’s a great grab and go scope. What you’ll get is the scope itself, a laser collimater, and one 10mm Celestron eyepiece. I’m not sure what happened to the original Orion eyepiece so I am substituting this one.  Asking $120 and will deliver to central Arkansas or meet you halfway farther out in the state.  Contact me at jamesdixonlr at or 501-258-1914.  If you are interested in the wooden tripod too let me know.
