Related Questions and Answers

Q: 1. Is the iPolar required the laptop to be connected all the time? Or after the polar-align with the laptop, the laptop is not needed anymore?

A: Yes it is needed for alignment only and once aligned, a computer is no longer needed.

Q: 2. Does the iOptron SkyTracker Pro rotate 360 degrees?

A: Yes...take 24 hours to rotate 360 degrees. Never needed to use it for more than about 4 hours though. Great addition to my night sky imaging kit.

Q: 3. Can iPolar align during daytime or does it only work with a night sky?

A: It works best at night. It can be used in daylight but it is tricky and not always accurate in daylight.

Q: 4. once polar alignment has been established can the iPolar be removed from the mount?

A: Yes, it is possible to remove the iPolar from the iOptron SkyHunter Portable EQ/AZ GoTo System with iPolar after alignment has been achieved.

Q: 5. What is a recommended Tripod other than the 1.75 inch carbon fiber that ioptron offers?

A: For the iOptron HAE29 GoTo Alt-Az/Equatorial Mount one needs to make sure one uses a tripod with the correct mount for the head. The iOptron Carbon Fiber Tripod (21-36.8") is the best option, BH #IO8061 (https://bhpho.to/3LtX21A).

Q: 6. Is a computer required for polar alignment and if one is needed will it work with a Mac?

A: An electronic polar scope is built into the mount and a computer is not required to use it.

Q: 7. How is the Skytracker programmed or set to track the sky based on location, season and time?

A: You simply use the included polar scope to do a polar alignment. Once it is polar aligned it will automatically rotate at the speed set with the selector switch whenever the power switch is turned on. This will give a rough polar alignment and ok tracking accuracy.For better tracking accuracy there are Apps available which allow you to enter your precise location and will then show precisely where in the polar scope reticle to align the pole star. This will give you the best accuracy possible with this unit.

Q: 8. Is the dove tail mounting plate included?

A: For the iOptron SkyHunter Portable EQ/AZ GoTo System with iPolar BH #IOSHEQA • MFR #SHEQA the base for the dove talpe plate is included. The dove tale plate is not.

Q: 9. So I bought this mount several months ago during the winter. I tried using their software to polar align (i bought the iPolar version), but was having a really difficult time doing so. The software seems to be super slow and getting an accurate lock on polaris was challenging. Does anyone have any tips?

A: I would recommend getting in touch with the Manufacturer directly for this kind of inquiry. They will be the best assistance for something like this. iOptronTel: (866) 399-4587 or (781) 569-0200 Website http://www.ioptron.com/ Email support@ioptron.com

Q: 10. Can a Samsun Galaxy S10+ phone be used for the alignment?

A: The iOptron Skyguider Pro does not use a smart phone for alignment. It used the built in polar alignment scope.
