Tele Vue 102iis - Manual (Page 4)

4
3.2 Finders
We particularly recommend using the Star-
beam reflex sight (part# SFT-1003), which
attaches to the Tube Rings. The case has a
cutout for the Starbeam. The Quick Release
Universal Finder Bracket (QFM-1008) can
hold a traditional 50mm finderscope and also
attaches to the mount ring channels.
4.0 Photographic Set Up and the Tele
Vue Imaging System
Using the 102iis for photography begins with
the insertion of the included Imaging System
adapter into the focuser. From that threaded
connection, the Imaging System accessories
provide a variety of options for camera adapta-
tion and focal length variation. The goal of the
imaging system is to let you pursue your
astrophotographic passion with ease. The
following summary of parts and pictorial dia-
gram will help you understand each part’s use
and its sequence in the chain. Please note that
spacing requirements of any particular camera
will need to be met by the appropriate Imaging
System spacer or combination of spacers.
