Alluna Optics delivers
24 inch optics to an Austrian observatory
Which amateur astronomer
doesn't dream of an observatory of his own away from the sea of light of
large towns? Richard Gierlinger from Schärding in Upper Austria has
fulfilled this dream himself. The preconditions were good, Richard Gierlinger
designs and manufactures big constructions as well as controls for telescopes
already for years.
The new observatory stands
on a hill without disturbing light sources away from traffic. The 5.5 meters
of dome houses the main instrument which can be radioguided from the first
floor.
The outbuilding was rebuilt
as a workshop. The situation is made for astronomical observations – on
one side the splendid Alps panorama, on the other side the look from above
at the 10 km remote Schärding.
What was still missing was
the main mirror for the main instrument, a 61 cm parabolic mirror with
a focal length of 2828 mm. The German company Alluna Optics received the
order for the production in July. The mirror was already completed in the
middle of September and coat with an aluminum layer. Wolfram Felber (Alluna
Optics) brought the parabolic mirror personally and visited the observatory.
Because of the good groundworks the mirror was inserted into the special
27-points main mirror setting in short time. After a short justification
of eyepiece statement, heliostat and main mirror the first starlight could
already be captured. The excellent measurements out of the examining laboratory
of lambda 1/10 PV wavefront (distance between the highest and the lowest
point of the surface profile) and a Strehl of ,985 were confirmed.
This night some objects were
still watched visually, unfortunately limited by a bright sky background
caused by a full moon. So the ring fog showed numerous contours in the
constellation Lyra despite full moon. The ball star cluster M13 was dissolved
up to the center just like M92 in an immediate proximity.
In future, the Newton telescope
will primarily carry out his jobs in the CCD photography and ferreting
little planets and comets out.
