This is a high precision Moonlite CS Model Single Speed Crayford Focuser for Celestron 11" and 14" SCT, Celestron 9.25" Edge HD with 3.29" thread and Meade 10", 12" and 14" SC telescopes with 3.25" SC-thread*. 

Comes with 0.95" Travel, Focal Reducer Drawtube & Brass Compression Ring in RED Colour

2" to 1.25" reducer included.

*As you notice there is a slight difference between Meade and Celestron large SC threads... Althought Celestron refers to this as 3.3", but according to technical documentations you will find a male 3.29" thread on the back of large Celestrons like 11", 14" and 9.25" Edge HD (the original 9.25" has got a 2" thread only), then you will find a male 3.25" thread on the back of large Meade SCs, like 10" 12" and 14", therefore the Celestron flange would fit both a Meade and Celestron, but not vice versa, that's why we will always stock the Celestron flange version.

The modular design of the CS 2" format Crayford focuser makes it easy to be configured for many different scopes. However, the vast range of configurations makes it nearly impossible to stock all variations here at 365Astronomy's premises, therefore we had to choose just the most popular combinations.

Other configurations are available on request.

ATTENTION! Single speed Moonlite focusers require a motor drive to be able to hold the payload, however if you wanted a Moonlite focuser without a motor drive, we'd recommend to go for a dual speed version with a clatch installed. Those models work without a motor drive.

SPECIFICATIONS

FLANGE:  3 1/4" SCT-style with tall FR-style that allows a Celestron or Meade f/6.3 reducer to be installed inside the focuser, screwed into the end of the drawtube (Moolite calls it 3 1/4" for simplicity, but in reality it is about 3.29" so that it would fit both Celestron and Meade SCTs as explained above)

DRAWTUBE:  0.95" travel, brass compression ring, FR-threaded (again, this is to allow installation of a Celestron or Meade f/6.3 focal reducer/corrector) (In the case of a C9.25 Edge HD this feature will be useless, just simply ignore it...)

FOCUS KNOB / MOTOR DRIVE: single rate focuser, no motor drive, but motor drive is optional (we chose this version, because we also stock the motor drive. It makes sense to install the motor drive onto a single speed focuser rather than a dual speed, so why spend money on the dual speed version if you will use it eventually with a motor drive only)

COLOUR: gold / orange

SIZE:

Overall length to 2" Eyepiece holder end: 114mm (plus add drawtube travel)

Overall length to 1.25" Eyepiece holder end: 117mm (plus add drawtube travel)

Diameter at base: 100mm

Load capacity: 5 lbs (although we saw other dealers advertise it as 6lbs, we took this info from the manufacturer's website)

Above picture shows the flange that is threaded for 3.3" SC like Celestron 11", 14" and Edge HD 9.25" or Meade 10", 12" and 14" SCT. Inside, at the end of the drawtube you can see a standard 2" Sc thread that is used for attaching a f/6.3 or f/3.3 reducer, very conveniently, inside the focuser (see image below as well...)

 

Features of the CS 2" format Moonlite focuser range as shown above. It is compatible with both 2" and 1.25" accessories. Please refer to the product specification.
