Optec Pyxis LE Rotator

The NEW Optec Pyxis LE is a low profile, lightweight, and versatile Camera Field Rotator with standard mechanical interfaces for ease of connectivity. Based on a design by Ted Agos of the Acorn Hollow Observatory, the Pyxis LE is the thinnest camera field rotator available today!

The telescope side of the Pyxis LE is a simple two-inch "push-fit" barrel. The long barrel adapter, just short of 2-1/2 inches, is easily inserted into any 2" focuser such as the Optec TCF-S Temperature Compensating Focuser. Combined with the TCF-S or TCF-Si, the Pyxis LE creates a focuser/rotator combination requiring less than 4-1/2 inches of back-focus.

The camera side of the Pyxis LE is a standard male T-thread. Any T-thread camera, filter wheel, off-axis guider, or industry standard T2 ring can screw directly on to the exit port of the Pyxis LE - no other adapters are required. All of the users existing accessories - T-thread spacers, off-axis guiders, filter wheels, etc. - can be attached directly. With the Pyxis LE, the confusion typically surrounding adapters is eliminated since the Pyxis LE is ready to use out-of-the-box. Simply attach your camera, slip into a 2-inch focuser, and you're ready to go.

The Pyxis LE is ideally suited for small, well-balanced cameras such as the QSI, Fish Camp, Starlight Xpress or SBIG ST-series CCD cameras. Canon and Nikon DLSR cameras will attach directly using an optional T2 bayonet ring. Optional T-thread extender rings can be added in 7.5 and 15mm lengths for additional offset to avoid filter wheel stepper motors such as with the SBIG CFW9.

f/6.3 Telecompressor Optics Integration

Pyxis LE f/6.3 Spacing DiagramThe Pyxis LE can also accommodate Schmidt-Cassegrain f/6.3 optics (or any 43mm diameter optical system) without adding additional back-focus. The f/6.3 telecompressors available from Celestron, Meade, Antares and Hirsch fit directly into the 2-inch nosepiece of the Pyxis LE. The optics must first be removed from their original housing and then using a pair of optional retainers the optical elements can be inserted anywhere within the 2" barrel of the rotator. Optec technicians will install customer supplied lenses for a nominal fee. This feature is essential when setting critical telecompressor or field flattener spacing to the imaging sensor. It should also be noted that the optics rotate with the camera so additional flat-fields are usually not required for different position angles.

Cutaway of the Pyxis LEThe mechanical design is exceptionally robust and rigid. The Pyxis LE's rigidity is due to two coaxial thrust bearings that provide support for small to medium sized instrument loads (2.5kg or 5.5 lbs. maximum). The large separation distance between bearing surfaces (2.28") further increases the stability of the Pyxis LE. This permits off-axis guiders, filter wheels, AO units and of course, the CCD camera, to be attached with no flexure. This unique bearing arrangement allows the rotator to be very thin and use only 0.68" of back-focus.

Interface Software and ASCOM Driver

Interfacing with the computer is also extremely simple. Just plug in the USB and 12VDC cables, let Windows install the drivers automatically, open up Pyxis-LE Control, watch it automatically connect, and start using your rotator. Additionally, the Pyxis LE is ASCOM compliant so it can be used in programs like Maxim DL. Intelligent anti-cable wrapping is programmed at the firmware level so you can expect a non-binding experience with both the control program and the ASCOM driver.

Easy to use Windows application allows simple control over your Pyxis LE camera field rotator.

Graphical position indicator allows for quick adjustments and instantaneous position feedback.

The View menu enables users to hide/show certain regions of the application to reduce overall window clutter.

Starlight Xpress USB Filter Wheel

The Starlight Xpress USB filter wheel is a new product for 2009 and introduces many new features to a useful imaging accessory. It is unique in that it does not require a separate power supply when used with USB control - the high performance DC gearmotor runs entirely from the USB supply and consumes less than 100mA. It is also capable of operation from a serial input, or from a switched hand controller, both of which power the wheel from a small dry battery.

The wheel is light and slim, with an easy change system of thumbscrews to swap filter disks without tools. A variety of threaded adaptors is available - T thread, SCT thread and Takahashi 72mm thread at the moment. The adaptors can be swapped by using a small screwdriver to release three stainless screws and lifting off the adaptor flange. Each flange can be rotated to any angle before locking down, so that you can orient the wheel and camera into the optimum position.

The wheel is quiet in operation and the Hall-Effect 3 bit encoded positioning gives absolute filter locations (not serially sequential) so you can easily swap between any filters without accidentally losing the wheel position.

Technical Specs:

Available with either 7 position 1.25" Carousel or
5 position 48mm carousel.

ATIK EFW 2 Motorised Filter Wheel

We’re pleased to introduce a new motorized filter wheel, with multiple filter
capability. This new wheel employs exchangeable filter disks, allowing for multiple
combinations, and has large 54mm openings on both sides. With these features, the
EFW2 can easily support sensors up to full frame (35mm) format.
The EFW2 also features a slick design, with
a slim and lightweight profile. For
example, the distance between any Atik
camera and the wheel itself is 0mm, while
still maintaining the possibility to rotating
the camera to any desired position. Total
extra backfocus needed will be only
22mm.
Initial filter disk options include
5x50.8mm, 5x2” mounted, 7x36mm and
9x1.25” mounted.
Optionally, there will be a hand controller box with push button functionality
permitting the use of the wheel without a computer.
On the sofware side, the EFW2 will have a ASCOM compliant driver, so that ant
compliant software can control it. Additionally, the EFW2 will work with our Artemis
Capture software, for easy, simple and efficient operation.
