14 | MOON FILTER
Your telescope accessories include a moon filter. It provides observations of the full or
light moon in rich contrasts. The moon filter is screwed into the eyepiece, when required.
CAUTION: Do not use this filter as a sun filter!
15 | ADJUSTING THE FINDERSCOPE
For daylight observation we recommend to use your telescope in combination with the
eyepiece H20 (45x) only. Direct the telescope to a far-distanced object and adjust a par-
ticular part of your object (church tower, top of a tree of crane, TV antenna) in the center
of your field of view. Now look through your finderscope which provides a reverse and
up-side-down image. Open the 3 screws of the support (4) slightly and direct the reticle
of your finderscope towards the center of your object. Tighten the 3 screws with care,
making sure that the reticle stays in the center of the image. Your finderscope is adjusted
now. It has a far larger field of view then your telescope and helps you to direct your tele-
scope towards your desired objects which you can observe then through your telescope
with smaller field of view.
CAUTION: Do not aim the sun with the finderscope.
You eyes can be seriously damaged.
16 | FURTHER HINTS FOR ASTRO OBSERVATIONS
Observe outdoors only, but not through a window. Train the hand movements a few times
at daylight. In case of temperature differences between inside and outside, the telescope
must get used to the predominant temperature in order to avoid fogging. Adopt yourself
and your eyes to the darkness in advance. To clean the optical surfaces make sure to use
appropriate fuzz-free optical tissues. Remove the dust with air pressure or a blow bellow.
Avoid strong rubbing. We recommend studying specializing literature on astronomy and
celestial observations. Enjoy your observations with your DÖRR Merkur 60A Telescope!
