The Pyxis 3-inch has a full 3 inches of clear aperture and is designed to hold large instrument packages without flexure or wobble. A 6-inch bronze worm gear and stainless worm rotate the center tube with a resolution of 0.01875 degree per step from the stepper motor. The operating software is very similar to the smaller Pyxis so that existing third party software is compatible. De-rotation of the field for long exposure images with alt-azimuth mounted telescope and rotation of the guide chip for SBIG camera to a suitable bright guide star are the two primary uses of this instrument. Power requirements and other operating conditions are similar to the 2-inch Pyxis model.

This model is large and heavy and is intended for larger telescopes on observatory caliber mountings. The 2.4-inch thickness warrants telescopes that can accommodate this increase in the back-focus distance. It uses the same telescope mounts and camera side adapters as the TCF-S3 - Optec's new 3-inch temperature compensating focuser. Any telescope mount or camera side adapter has to be ordered separately.

Like the 2-inch Pyxis model, the unit can only be controlled by a PC computer running the Optec PYXIS.exe control software or third party compatible software. Manual control is not possible. A flat wire serial cable is available for connection to a standard RS-232 interface COM port at 19.2K baud. Standard lengths and custom lengths up to 100 feet are possible. Cables and COM port adapters need to be ordered separately. A 15 VDC regulated power supply is included with a right angle 2.5 mm power jack.  Stepping up to 15 volts DC provides about 20% more torque without sacrificing speed.  Contact Optec to upgrade to the 15 VDC right angle power supply for your existing Pyxis 3-inch.

Great device and excellent service.

This is my first experience with Hyperion. I had quick shipping and good service. The eagle is an excellent device for controlling my telescope and camera. It is a powerful pc.

Really does the job...

For those who have the Eagle, the ECCO is a great device to monitor and adjust the dew heater. It is very easy to install. You do a short calibration in the advanced settings, be sure the sensor is properly placed, plug in the cables and bingo--all done. Highly recommend it.

Great Software

Amazing program, so much you are able to do with it. Very costomizable. Great software support as well, quick replies and helpful. As an amateur astrophotographer it’s pretty easy to learn and the program can grow with you as you dive into the more advanced features.

Successful imaging

I am still learning all the capabilities of Prism, and so far very pleased. I have had several nights so far, after easy setup, of sound sleep waking up to multiple quality subs. I have tried many automation software packages and very happy with Prism.
I asked about some simple issues on initial setup, and customer support was very fast and super friendly.
Give Prism a try.

Nice compact Setup

This is a nice and easy-to-use short focus Newtonian with a very good mounting. A basic knowledge of astronomy is needed to properly use this telescope, as the telescope needs to be colimated to get best results. The mounting needs to be properly oriented to the sky as well.
