This TMB-130 Signature Series apochromatic refractor is one of the finest optical instruments, both optically, and mechanically, that TMB Optical has ever designed – with the best price to performance of any apo refractor on the market, bar none. It's a Sky & Telescope Hot Product for 2007 . . .
This low profile step-down adapter allows the use of 1.25" eyepieces in 2" focuser drawtubes and 2” star diagonals and provides a shorter light path than the standard TeleVue adapter to allow eyepieces to swing through the drive base of many catadioptric scopes . . .
Temporarily out of stock; will charge and ship when available.
This Crayford-type 1.5” drawtube travel Feather Touch 2" focuser is precision-machined for use with Schmidt-Cassegrain and reflector telescopes. The friction-drive focuser’s compression ring accessory holder and zero image shift/no backlash design makes it ideal for critical CCD imaging and astrophotography . . .
Temporarily out of stock; will charge and ship when available.
This adapter threads onto the rear cell of 11” and 14” aperture Celestron catadioptric telescopes to hold a Feather Touch focuser with 1.5” of drawtube travel without vignetting . . .
Temporarily out of stock; will charge and ship when available.
Designed to work with most Celestron 8” and 11” Schmidt-Cassegrains. Not for the 8” Ultima 2000, older Ultima 8 PEC, or Ultima 9.25. It will also work with the non-GPS NexStar 8. However, the focuser will hit the drive base of NexStar 8, preventing the scope from reaching the zenith when the focuser is attached . . .
Temporarily out of stock; will charge and ship when available.
This JMI Motofocus electric focuser is designed for use with all Meade 8” and 10” Schmidt-Cassegrains and 7” Maksutov-Cassegrains that do not have a Meade focus control unit . . .
This 1.25" 45° image erector threads onto the rear of Meade ETX-60AT and 70AT refractors only. It will not fit the Meade ETX-90/105/125 or any other telescope . . .
If you are looking for the best fast focal ratio/ultra-compact apo refractor Tom Back could design, then look no further. This 13.25" long TMB-92 fills the void left by the discontinued 90mm Astro-Physics Stowaway (a legendary scope that sells for up to $6000 on the used market). A customer wrote to tell us “I have a 92 from the first batch. Visual performance defies the laws of physics” . . .
