During
1998 he replaced his Tamron 300mm lens with Nikon 300mm and 400mm lenses and upgraded
my hypering kit to support high vacuum film hypersensitisation. During his first
two years of experience in astrophotography he became increasingly aware of the
need to cover focal lengths in the 1000mm range. Therefore late in 1998 heI made
two major acquisitions: an AP 900 GTO mount and an AP 155 EDF f/7 refractor with
4" Field Flattener (shown to the right) In
October 2000 he replaced his 10" LX200 OTA with a 12.5" Ritchey-Chretien
from RC Optical Systems to support higher quality in wide field photography. The
RC has other advantages, such as 1/6 wave optics, a superb focusing system, and
very good thermal stability (the focus does not shift during the night). A little
later, in February 2001, he made a move into CCD imaging with the purchase of
an SBIG ST-8E camera. Unusually in this case, an OAG was being used in conjunction
with the ST-4. |
Philip
Perkins - Understanding the Universe He started to become seriously involved in astrophotography in December 1996. To support the quality he required he started making regular astrophotography trips to the south of France, however many of his images are taken from the back garden of his house in Wiltshire. |
