5. Optional accessories (not included
).
The Omegon Dobson telescope is supplied as a basic
setup configuration i.e. only the optical tube and base. The focuser, finder scope and other
accessories such as eyepieces are not included. Why? Because we want to give users the chance to
configure the telescope to their own needs. For example if you have your own telescope eyepieces
you surely don’t need to buy new ones, simply use the existing ones and save. For the focuser we
offer different focusers, basic and high-end focusers, the user can choose the ones which better suit
their needs. Because these optional accessories are being constantly improved and update the
following instructions are a basic guideline on how to install them to the telescope.
5.1. The
focuser.
The focuser is an essential part of the telescope as it is used to get precise focused images.
To install the focuser release the two set-screws as shown in figure 17 and insert the focuser base
tube. Make sure the base tube fits the focuser base. The set screws should now be retightened to
hold secure the focuser.
5.2. Finderscope.
The finderscope is also an
essential part of your telescope as it helps to
locate the objects to be observed through the
telescope’s eyepiece. There are two main types
of finderscopes, LED finders or the optical
finders. This Dobson telescope uses Vixen-
compatible-type findershoes, this means it is
compatible with the original
Vixen®/Celestron®/Orion®/ Meade® and other
compatible finderscopes. See Appendix A to
learn how to use a LED finderscope.
5.3. Eyepiece Rack.
The eyepiece rack (not
included) is used during the observation
sessions. Eyepieces, Barlow lenses, adapters or
other accessories can be kept in the rack and
changed whenever necessary. This a great time
and accessory saver as well.
