JIM Reverse Crayford Focusers for Telescopes

Item No. 765-61500
Manuf. No. JMI RCFMIN1

Eligible for Scope City Rewards at Check-out

SHIPS ONE WEEK AFTER ORDER

JMI Reverse Crayford Focuser Mini-1 RCF 1-1/4" for Telescope - A 1.25" Reverse Crayford focuser. (Specify the Interchangeable Base options--see below.). Unlike the standard Crayford focuser, whose drive shaft presses directly on the focuser drawtube, the drive shaft presses on an extension of the focuser drawtube, providing dimensional stability without necessitating a large, heavy body to the focuser. As a result, this focuser is very light and makes an excellent replacement focuser for a lot of the low-end focusers found on inexpensive newtonian scopes.

NOTE

  • Due to the design of this focuser, the knobs are at a 90-degree orientation from most, placing the drive shaft perpendicular to the optical tube when using a curved base.
  • This Model mini1 Newtonian Version does not include Motor. A motorized version is available at extra cost.
  • This focuser (pictured) has the flat base option. A curved base is also available for the same price--please specify make and model and size of scope when ordering.
  • A locking brake (thumbscrew) is on the back of the drive block.
