Ideal for long-exposure astrophotography and imaging, Losmandy G11GT-LT Equatorial GoTo Mount Head Onlyprovides users with a powerful platform built to support and move larger optical tube assemblies (OTAs) and gear with precision. With a total payload capacity of 75 pounds, excluding counterweights, and a unique 360° rotating declination axis, the G11GT can precisely track the more than 40,000 objects in its database for extended periods of time without vibration and the need for the time-consuming "meridian flip" that is common with many equatorial mounts.

All hardware is made of stainless steel to handle the weight as well as resist wear over years of use, while a dual dovetail saddle will accept the common Vixen-style plates and the larger Losmandy D-style plates. Its dual axis DC servo motors are smoother and more precise than the more common stepper-type motors and are reversible for use in the Northern and Southern Hemispheres. Losmandy is offering this version of the G11GT without a tripod for those users who already have a reliable support system such as a heavy-duty tripod or pier.

The brain of the G11GT system is Losmandy's Gemini 2 computer hand controller. Equipped with a 40,000+ object database and updatable via the Internet, it sports a full-color display, an intuitive user interface, and an Ethernet 10/100 port for remote PC control. It features Periodic Error Correction (PEC) and declination-axis backlash correction to improve tracking accuracy and precision, with smooth tracking over long periods of time. Alignment assistance is available by selecting at least two bright stars, with the option of aligning to more stars for improved GoTo and tracking accuracy as desired. Multiple guide, slew, and tracking rates allow it to be easily aligned and manually controlled, and to accurately track near- and deep-sky objects. A non-volatile memory and real-time clock preserve settings, including the backlash correction and PEC, when the system is turned off and power disconnected.

Q: 1. does this come with the 110v power adapter?

A: The Sky-Watcher EQ6-R Pro Equatorial GoTo Mount with Tripod Kit BH #SKEQ6RV2 • MFR #S30300 does not come with an AC adapter.

Q: 2. Does this have the latest one piece spring loaded worm block?

A: Yes all of the G11 goto mounts now have the tucked version of the motors, one piece worm and spring loaded worms. Here is a great reference Spread Sheet: http://losmandy.com/files/collateral/Losmandy_G11G_datasheet.pdf

Q: 3. I have a skywatcher 250 model 10 inch. With the rings cradle attached it is 32.7 pounds. Will this mount handle it?

A: Yes, the Sky-Watcher EQ6-R Pro Equatorial GoTo Mount with Tripod Kit will handle it. The mount's maximum load is 44 lb.

Q: 4. What is the manufacture date for this G11, and does it include Gemini-2 "Mini" goto controller?

A: We have the latest version with the Mini controller.

Q: 5. Is this the regular HEQ5 or the HEQ5 PRO?

A: This is the information from Sky-Watcher website. No mention of the word pro. https://www.skywatcherusa.com/products/heq5-mount

Q: 6. Is this the newer model which includes a USB A port for direct PC connection (by passing the hand controller)?

A: This is Sky-Watcher product # s30300 as per Sky-Watcher website: https://www.skywatcherusa.com/products/eq6-r-pro

Q: 7. How do you use this mount at 6 North latitude?

A: It has a 15-70° latitude adjustment range. Observers at lower latitudes will prefer to leave the alignment peg between two legs to avoid the counterweight from making contact with the tripod leg when the counterweight is in the lowest part of its swing.

Q: 8. Is the tripod section on this mount the same tripod as is used in the Celestron VX Advanced mount?

A: No the Celestron CGEM II Tripod that comes with the Celestron CGEM II GoTo German Equatorial Mount is not the same tripod that comes with the Celestron Advanced VX GoTo German Equatorial Mount.

Q: 9. Will this mount handle the SkyWatcher 300mm (i.e., 12") aperture OTA?

A: The Sky-Watcher EQ6-R Pro Equatorial GoTo Mount with Tripod Kit BH #SKEQ6RV2 • MFR #S30300 maximum payload is 44 lbs. the Sky-Watcher Quattro 300P OTA Imaging Newtonian 12" is 57 lbs.

Q: 10. Is there a case that will fit the head unit without the tripod

A: Probably one of the Pelican trunk cases. depending on the head dimensions only.
