Sirius 100ED EQ-G Refractor with GoTo Controller
ED100 provides high-contrast images that only a premium apochromatic refractor can deliver
The ED100 sports a multi-coated 100mm objective lens doublet of 900mm focal length (f/9.0)
One lens element is made of extra-low dispersion (ED) glass to all by eliminate chromatic aberration
The ultra-stable Sirius EQ-G Mount comes with a GoTo hand controller with 13,000+ viewing objects
Mount also accepts a standard dual-axis hand controller. One-year limited warranty
This is a telescope for the astronomy purist who wants the pristine, high-contrast images that only a premium apochromatic refractor can deliver and the object-finding precision and convenience that only a well-made GoTo mount can offer.
The ED100 delivers images remarkably free of chromatic aberration, thanks to the FPL-53 extra-low dispersion "ED" optical glass in one of the two objective lens elements. That, combined with the 900mm focal length (f/9.0), ensures that bright stars, planets, and the lunar limb won't be marred by color fringing. What's more, the 100mm aperture gives it 56 percent greater light grasp than our ED80, letting you push the magnification higher to resolve finer details. The baffled, 36"-long aluminum tube is outfitted with a 2" Crayford-style focuser (with 1.25" adapter) for exceptionally smooth focusing without backlash.
The Sirius EQ-G has the stability you need to enjoy steady images at high powers. With the GoTo controller, you will never run out of fascinating targets to view. And once you get a taste of automatic, computerized pointing, you will never go back to manually "searching" for objects again! The mount's internal dual-axis stepper motors slew your telescope at up to 3.4° per second right to your target.
Other features include a CCD autoguider port for imaging, periodic error correction (PEC), backlash compensation for GoTo slewing, latitude and azimuth adjustments for polar aligning, and an illuminated polar axis scope. The tripod is remarkably sturdy, featuring extendable 1.75"-diameter stainless steel legs and a cast-metal spreader plate.
Requires 12-volt DC power source such as the Orion Dynamo or AC-to-DC adapter for use of household 110-volt power. One-year limited warranty.
For owners of the Sirius EQ-G GoTo Mount whose version of the GoTo hand controller is 3.0 or greater, the GoTo hand controller's firmware can be updated over the internet.
Updating the GoTo Hand Controller's Firmware
From version 3.0 and up, the GoTo hand controller's firmware can be updated over the internet.
System Requirements
GoTo hand controller version 3.0 or greater
Windows95 or later
An available RS-232 COM port on the PC
Computer interface cable (supplied)
DC power supply (7.5V to 15V @ 100mA or greater output with 2.1mm tip positive plug)
Preparing the Computer for the Update
1. Create a folder where you will store the files necessary for the update.
2. Click on the Download Firmware Files link below and save the Firmware Loader program to the folder you have created on your computer. You will need to download this program only once; after it is saved on your computer, only the firmware data file is needed for future updates.
3. Download and save the firmware update date file to the folder you created. The file will be named OrionVxxxxEQ.ssf, where xxxx indicates the version number of the firmware.
Updating the GoTo Hand Controller
1. Plug the modular plug end of the computer interface cable into the middle jack in the hand controller. Plug the serial connector end of the cable to the COM port on your PC.
2. Press and hold down the 0 and 8 numerical buttons simultaneously, then plug the power supply into the hand controller's DC power jack. The hand controller will beep and display "SynScan Update Ver. x.x" on the LCD screen.
3. Run the Firmware Loader program on your computer.
4. Click on the "Browse" box and select the OrionVxxxx.ssf file location where it was saved previously on your computer.
5. Click on the "Update" button, and the new firmware will begin loading into the hand controller. The Firmware Loader will show the progress of the update on your computer screen. It will usually take approximately 5 minutes for the new firmware to load into the hand controller. It may take significantly longer if a serial-to-USB adapter is employed on your computer.
6. When the download is complete, the Firmware Loader will display "Update Complete".
The firmware in the GoTo hand controller has now been updated. You can click on the "HC. Version" button to confirm the new version number of the firmware (and possibly the database, but the hardware version will not change with internet updates).
Note: If the error message "Can not connect to a SynScan hand control" appears on your computer, check all cable connections. Also, try closing all other computer programs that might be attempting to use the COM port.
Note: If the error message "Firmware update failed..." appears on your computer, remove the power plug from the hand controller, and then reconnect it. Now, repeat the firmware update procedure.
By default, the data communication rate between the GoTo hand controller and the computer is 115kbps. The RS-232 port on some PCs may not support this high data transfer rate. If the firmware update procedure fails after a few tries, try reducing the data transfer rate by pressing the SETUP button on the hand controller. This will reduce the data transfer rate to 9.6kbps. The controller's LCD screen will show "Lo" in the lower right hand corner to indicate the lower transfer rate setting. The firmware update procedure remains the same except it will take much longer for the firmware to load into the hand controller.
