Solar Observatory

Our solar observatory utilises a 90mm Coronado Hydrogen Alpha filter connected to a Takahashi Sky 90 refracting telescope. This equipment is piggyback mounted on a Meade 10 inch computer controlled scope for solar tracking. Solar viewing is made through Denkmeier binoviewers which are fitted with twin eyepieces.

Under good seeing conditions, this equipment provides for some stunning solar views.

Coronado make some of the best solar filters and the 90mm model is one of the largest in their range. These filters isolate the sun's light to the Hydrogen Alpha range in the solar spectrum, blocking all other wavelengths. At this wavelength it is possible to see detail on the solar surface, including magnetic storms in the form of sun spots. Promenances and solar flares can also be witnessed by using the in-built TMax to tuner to zoom in on their specific wavelength.

By using the Denkmeier binoviewers and twin eyepieces it is possible to give the impression of curvature on the solar surface. An in-built feature of the binoviewer also allows an instant switch between 1.1 and 0.6 of current magnification.

Solar safety is of paramount importance and we take great care in this respect. All lenses and finder scopes are removed from the tracking scope which also has multiple fixed lens caps locked in place. The solar scope has a permanently fixed, secure filter covering the full aperture of the telescope. Our astronomer checks the view through the eyepiece each and every time before any member of the public approaches the telescope.

Viewing the sun through any magnifying instrument is dangerous and you should never attempt to do this using your own telescope or binoculars as blinding can occur. We use dedicated and specialised viewing equipment along with safe viewing practices to ensure the safety of our guests.
