The Pyxis camera rotator was especially designed with the guiding chip of the SBIG ST-x CCD cameras in mind. Simply locate a suitable guide star, enter the position angle and let the Pyxis rotate the camera so that a bright guide star is centered on the tracking chip. For those with alt-azimuth mounts, the Pyxis can de-rotate the field while tracking an object. A simple Windows interface program is provided which provides both position angle rotation and de-rotation control modes.  The control software is free and updates are also free.

Utilizing a precision sealed 50mm bearing, the Pyxis provides the rigidity and stability you have come to expect from Optec instruments. Weighing under 2 lbs the Pyxis can support and rotate the SBIG ST line of cameras without slipping. If the holding torque of 27 inch-pounds (3 Nm) is exceeded, the drive gear will slip but no damage to the Pyxis will occur. The running torque is 9 inch-pounds (about 1.0 Nm). This limit to the holding and running torque will also prevent damage to cables and instruments if a rotational stoppage does occur. The Pyxis can handle the SBIG AO-7 adaptive optic with camera. The clear aperture of the Pyxis is 1.65 inches and adds about 1.6 inches to the back-focus. For large instrument packages or systems that use the SBIG STL camera with large CCD, the new Pyxis 3-inch model is suggested.

Intelligent firmware will choose the best direction for each move to keep camera cables from binding. The built-in circuit board provides all the control needed - no external hand control box is required. Windows control software is provided with the Pyxis and software integrators will appreciate the simple command language allowing them to easily select a new position angle or activate the derotation control for alt-azimuth tracking.

The Pyxis was designed for use with the Optec TCF-S Focuser and IFW Filter Wheel. Fully compatible with the Optec NextGen MAXfield and NextGen WideField telecompressors the Pyxis can be used at 1X, 0.5X, and 0.33X using any SBIG camera. However, the NextGen telecompressors used with the Pyxis are not compatible with the SBIG cameras having an attached CFW-8/9/10 filter wheel. In this case the back-focus distance for the NextGEN reducer is exceeded.

I just took a series of 20 minute video sequences with my C11 in Alt/Az configuration from my front verandah through a narrow band H-alpha filter and the derotation was near perfect with the small stars on the periphery of the field showing as pinpoints. Very satisfying! - Dr. Jack Giles, Queensland, Australia - October 1, 2009.

New Firmware And Circuit Board Available

New firmware is available for the Pyxis 2-inch and 3-inch models. It was suggested that the unit have the ability to adjust the HOME or 0 position angle by software means instead of physically rotating the unit. Seeing the wisdom of this, the firmware has been modified to allow the user to set 0 PA within +/- 15 degrees of the default position. Cost is $25.00. New control software version 1.30 must be downloaded to make use of this new command. This firmware is only compatible with Rev. 1 circuit boards for the Pyxis 2-inch. Earlier models require a circuit board replacement. Special pricing is available for those users who desire the upgrade. Call Optec today!

Customer Reviews:

Read an Astromart review  of the Pyxis written by Bob Benamati, noted astro imager. Keep in mind that his Pyxis was one of the first and was equipped with the original low torque motor and not the high torque model used now.

The Ewell Observatory  in California has many dream telescopes with the latest high tech gear. Browse their web site to see the Pyxis mounted with various camera configurations and view the results.

Exceptional Mount

A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

You can very easily watch the motor consumption and know where the unbalance is....that easy. I have so much data that it is becoming difficult yo keep up.
I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding... just start imaging night after night after night.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS
