●How to use finder bracket
The finder bracket is provided, it locates on the upper side of the tube ring for the
purpose of connecting and fixing the finder. There are various types of finder for
users to choose.
Due to its low magnification and wide field of view, users can more easily and quickly
find the targets. Here are the using steps:
①Insert the dovetail of finder bracket right into the finder base, tighten it with screws.
② Adjust the finder and refractor tube until their optical axes are parallel. A simpler
way is to aim at a certain ground object, calibrating until the targeted object sits as
exactly at the center of your field of view as through the refractor tube.
③You can first target the bright stars around a perspective subject with your finder.
Because you have adjusted your finder optical axis paralleled to that of the tube, you
can observe the goal star through the tube.
●How to use 360°rotator
We provide 2.5" focuser together with a high-quality 360° rotator, which is quite
helpful for astrophotography.
This rotator comprises 3 adjusting screws and 1 tightening screw. Loose the tighten-
ing screw and then you can rotate the focuser.
The focuser rotates slowly and evenly because of damping phenomenon. Even the
focuser bears certain resistance when working, the converter won’t slip or misalign
due to our reasonable design and exquisite craft.
Users can adjust each of 3 adjusting screws so the rotator can rotate more easily.
(Caution: the adjustment range of the screw is not large, so please handle them with
much more care. Do not over-loosen the screws which may entail entire fall-off of the
angle adjuster.)
We have already properly adjusted the rotator, so self-adjustment is not really rec-
ommended.
