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 focusers 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 . . .
