SKY-WATCHER SOLARQUEST MOUNT

Sky-Watcher launched recently an azimuthal mount designed specifically for solar observing
1
. The
SolarQuest mount has many interesting features. A built-in GPS automatically enters date, time and
location and calculates the altitude and azimuth of the Sun. The mount then points the telescope to
the correct altitude and slews clockwise to find the Sun. When the Solar Sensor detect the Sun the
mount lock onto it and begins tracking. It is that simple.

The SolarQuest mount is designed for use with solar telescopes only. Do not point any other type of
optical device at the Sun. Looking directly at the Sun without verified-safe, professionally made solar
filtering will cause immediate and irreversible damage to your eye.

adaptor panel).

Using the SolarQuest mount is surprisingly easy. The mount is lightweight and includes a tripod. The
tripod and pier extension are the same supplied with the SW AZ GTi mount
3
.
After levelling the tripod and attaching the solar telescope, the only thing left to do is to turn on the
mount. SolarQuest then gets a GPS fix (about 1 to 2 min) and raises the OTA to the correct altitude
and starts to slew in azimuth until it finds the Sun.
When you use the mount for the first time, the 8-way slide switch should be used to centre the sun
in the field-of-view. The power button should then be pressed twice, and this offset is stored and
applied every time the mount is switched on. It is that simple.
Under clear skies the mount tracks the Sun flawlessly, keeping the Sun it in the Field-of-view for
hours.
Point to the Sun automatically:
1. Turn on power. The SolarQuest will level the solar telescope automatically and then takes up
to 2 min to acquire GPS lock before the next movement.
2. The SolarQuest will bring the solar telescope to the elevation of the Sun and starts slewing in
clockwise in the azimuth direction to search for the Sun.
3. The red LED (figure 3) will blink slowly during the search and becomes solid after the
SolarQuest mount locates the Sun successfully.
4. Use the 8-way slide switch (Figure 3) to centre the Sun in the FOV of the eyepiece. It is
normal to find lags in movement when switching to an opposite direction.

5. The Sun might be off-centre in the eyepiece after the SolarQuest finishes the auto-pointing
routine. After centring the Sun manually in the eyepiece, users can double click the power
button to save the corrections. It will be applied to the next auto-pointing routine.
Tips:
•Before turning on power, pointing the solar telescope to the left side of the Sun can reduce
the searching time.
•Use a long focal length eyepiece (e.g. 20 to 25 mm) to start observing.
I did not test the SolarQuest mount with cloudy skies. However, I was able to verify that, after the first
auto-pointing routine if the Solar sensor is covered the mount continues to track the sun. This means
that the Solar sensor must detect the Sun at least once to star tracking.
SolarQuest can be powered by 8X AA batteries or alternatively via a 12v power supply. To use an
external power supply, the battery cover and battery cassette has to be removed and a different
battery cover with a built in 12V socket must be attached.
Overall the SolarQuest mount is very easy to use and works exactly as described by the manufacture.
