This is a 2000 Orion 1.25-inch rack and pinion focuser mpn 13031. Aside from the "China" decal on the side, this focuser has remained quite unchanged since it was introduced in their catalogs back around 1997. It would have been used on their 6 and 8 DSE reflectors.
This particular model would have come on the earliest XT4.5, 6, and 8 reflectors.

Really, for what it is, I find it to be a fantastic focuser. It is lightweight, extremely smooth-functioning, has no wobble, and holds a hefty amount of payload.

Construction is pvc hard plastics
Weight is 5 oz
Total focus draw is 1.93-inches
Bolt pattern is 2.78-inches L x 1.22-inches W
Curved to fit up to 9.5-inch optical tubes. Will fit to either sonatubes or tin/aluminum tubes.
Tested to handle up to 1 pound without drooping at zenith position.
Increase or decrease friction by loosening or tightening the (2) Philips screws on the back.

The focuser is in practically mint condition. Really hard to see that it has ever been used. Focusing action is perfect in all aspects. No color fade, chips, scratches, ect. You will need your own mounting hardware, but this does come with the original, large aluminum set screw and top dust cap.

Price includes shipping if in the US and by check. Paypal and/or other nations will be more.


  • Condition very excellent to mint
  • Location Veradale, WA
