Photographic
observations
Use a miniature reflex camera with an
objective’s thread M4x0.75 to take
pictures of celestial objects.
To operate with other photo cameras,
use adjusting rings, selling in the
specialty stores.
To mount a camera on the telescope,
take off deflecting mirror (1), screw
() and bushing (3).
Unscrew the camera objective
lens.
Screw the bushing into the
camera.
Insert the camera () with bushing
into the eyepiece tube () and
secure them by the screw (3).
Perform the shooting of bright
objects that need a second
exposure (the best object is the
Moon). Otherwise, pictures will be
blurry due to the diurnal rotation of
the celestial sphere.
It is necessary to use a special
bracket (not included in the delivery
set) when working with a digital or
video cameras.
Long-time exposure is needed for
taking pictures of weakly glowing
objects (separate stars, nebulas).
This astrophotography is possible
with the use of the parallactic
mount with a clock electric drive at
polar axis (TAL-M, TAL-50K) and
special off-axis guide GV-.5
