MicroGlide Epsilon Focuser
(motorized autofocus capable). An ultra-sensitive 2" secondary focuser
for SCTs with existing primary focus, as pictured at right. A patented Van
Slyke Drive mechanism moves the tube in and out like no other focusing mechanism
before it. The MicroGlides offer ultra-smooth and tactile-sensitive [micrometer
head] control for micro-focusing applications. No other focuser on Planet
Earth provides this type of unparalleled and sophisticated focusing operation.
Optional autofocus control offers the finest step-to-tube movement ratio
available. More than a factor of 10 better than any other focuser on the
market (one motor step = 0.0000069" of actual tube travel). Order optional
Docking Adapters as described below. Pictured at right is what you receive
when you purchase the MGF1.
Item MGF1: $649
Docking Adapters,
required to dock Epsilon focuser to your scope. Optional docking adapters
are available for all popular scopes on the market. They are listed at the
DOCKING ADAPTERS link above right. If you don't find your specific docking
adapter, call VSI and we'll custom machine one for you. Interchangeable docking
adapters provide the use of multiple scopes utilizing one Epsilon focuser.
Pictured at right is a representation of what you receive when you purchase
a specific docking adapter for your telescope.

Robo-Focus stepper
motor, required to autofocus [computer control] your MicroGlide focuser.
You must order the electronics hardware package from Technical Innovations
(TI). See AUTOFOCUS link above right for more info and direct link to TI.
All Robo-Focus gear reduced stepper motor control offers temperature
compensation. TI stepper motor includes wired and mounted DB9 plug. Pictured
at right is a representation of what you receive when you purchase this item.

*IMPORTANT NOTES follow:
MGF1 Epsilon focusers are designed to be SECONDARY focusers, and do not require drawtubes, but do require a docking adapter. They do not include built-in drawtube capability and have standard 2" ID moving tubes that accept your 2" format barrel nose eyepieces and accessories.
MGF2 Omicron focusers are designed to be PRIMARY focusers . They require optional moving tubes, with a 2.25" inside diameter, that do not accept your standard 2" format eyepieces and accessories, and require the use of our optional 2" format drawtubes, offered separately at the DRAWTUBES link. This functional design offers near-zero profile, full drawtube insertion into the Omicron's moving tube. This unique drawtube option provides your Omicron with more back focus range (up to 12" with custom drawtube) than any other commercial focuser available today, while also providing a selective choice of back focus travel, depending on which drawtube you choose. Drawtubes, Docking Rings & Spinners sold separately.
MGFC??s are designed to be 2.7" COUPLING focusers mainly for hi-end APO refractors, and need no other drawtube, docking adapter or accessory to operate. Depending on which model you choose, your co-focuser will have built-in male and female threads for an AstroPhysics, Takahashi or Meade refractor. They are not interchangeable between the three scope thread formats and are dedicated to the scope format you choose. They have an oversize 2.25" clear aperture, so the largest CCD chips will not be vignetted by passage of your scope's light cone through the co-focuser to get to your CCD camera. The major advantage is to add autofocus capability to your scope without fussing around with "Mickey Mouse" modifications to your existing scope's focuser via aftermarket universal mounting kits that really don't properly fit any scope.
