Flat-FtElld Super Quadruplet Refractor, This is & sIBle-of-the-&1l four element In four groups IIstrogrllph uses 2 ED elements for high order color corrections. In order to USll the FSQ-106ED to thll limit of its capabilities. pleasa 'elld this manual lind fam,llIrile yourllelf wilh the parts and Iheir functions before using this instrument.

;!\WARNING

NEVER ATTEMPT TO OBSERVE THE SUN THROUGH THIS TELESCOPE WITHOUT A FULL APERTURE SOLAR FILTER DESIGNED FOR THIS PURPOSE. FAILURE TO DO SO COULD CAUSE INSTANT BLINDNESS. COVER THE FINDER WITH AN OPAQUE COVER TO PREVENT ANY LIGHT FROM COMING THROUGH. AN UNCOVERED FINDER CAN ALSO CAUSE SERIOUS DAMAGE TO THE EYE. KEEP CHILDREN AWAY FROM THE TELESCOPE DURING DAYTIME.

Lt CAUTION

When placing Ihe tube assembly on to.n equator;,1 mount, be c.retullO
balance Iha lube in the saddle. This will !Xeventlnjury to tlngers and will
prevent II f,om failing to Ihe ground. When placing the lUbe IIssembly in the
saddle. always hold Ihe lube with one hand 10 keep II f,om falling off the

saddle on to Ihe ground.

Always lay Ihe lube assembly on a completely l1at surface thattouolty sup-
pans it 10 protect II from damage.
Kllllp Ihelube assembly out 01 the SUN. Otherwise. the tube assembly could
heat up, causing lens damage.
G,ut care should be taken to focus the instrument to insure the sharpest

possible image.

Improved Color Correction
As 8 result of using to high performeroce ED glass alemants, and by positioning the G3
element close (0 the G2 element, the FSQ
106ED has dramatically Improved oorreeOOn
for color and sphericalaberrlliOfl. The !'leW

It was designed 1o be used with digital SLR's and CCO cameras.

Enhanced Back Focus

The FSQl06ED has been designed with a back locus 01 178mm. This enhanced back focus will allow the imagl! or observer to ~e any combination 01 CCO camera, bino viewer or diagonal with their FSQ-l06ED.

Observation of deep sky objects In general, oblefVaing deep sky objects reo quires a low power, wide field ocular which produces the maKimum brightness. On the other hand, obsetving globular clusters and smllil nebulae requirea high magnllication. This is particulally tlue in cities with high sIcy brightness.

Additional Precautions I ==~~~==='I II
Keep the IIllescope away from large fluc tuation, in temperature. When the instru
mel'll is brought out Irom 1I warm room
to colder air, dew mey form.
Store the telescope in l! cool dry envl. ronment. Any dew should be removed
by blowing it with 8 hair dryer with Ihe heating element turned off. which means the eir will beat room temperature. This
flow 01 cool, room temperature air, will
dry the dew end 1'101 leave 8 residue. Ad
ditionally, it is 8 good idea to store the
telescope with II desicant [drying IIgent) nllar the objective to keep lIny moisture away from the objective.
As mentioned previousllly, never use
canned air due to the fact that the pro pellant is a refrigerant which could cause
