Information for Amateur Astronomers  
Observing Conditions

Generally, the limiting magnitude at the zenith ranges from 6.0 to 6.5 and there is no serious light pollution. However,
during the soccer season (March to October), the nearby soccer field will turn on their lights 2~3 times a week and the
southeastern sky becomes less than perfect.  As these lights will be turned off by 22:00 at the latest, all-night observing
will not be affected.

Ballandean Village  is situated at the highlands 700 to 1000 metres above sea level and 170 km inland. As a result,
humidity is much lower and the number of observable nights is greater than the coastal areas. The naked-eye limiting
magnitude is routinely 6.0 - 6.5.  On clear mid-winter nights the temperature falls very quickly overnight (down to -5
degrees or lowe
r) and this may cause condensation on mirrors or lenses. Under these conditions, you may need a
special heating device or hair dryer to continue observing overnight.

Unique Stanthorpe accommodation
TWINSTAR GUESTHOUSE & OBSERVATORY
B&B with an astronomical observatory
Twinstar Guesthouse & Observatory is B&B accommodation with an in-house
observatory. We introduce our guests to the beautiful night sky from our
observatory (night sky tour) on every clear night. The night sky tour is geared
towards guests who have never looked through a large telescope or those with
limited observing experience.

Our location is suited to amateur astronomers, too, who want to enjoy observing
under dark rural skies.  The 18-inch (46cm) telescope is used for the night sky tour
and not available for guest use. However, for experienced observers, a 16-inch
Dobsonian telescope will be made available.
