Using The Virtuoso For Astronomy - SKY-WATCHER VIRTUOSO Instruction Manual

USINg The VIRTUOSO fOR ASTRONOMy

To setup the Virtuoso for astronomical use:
1 . Loosen .the .locking .knob .on .the .mounting .platform .Slide .the .dovetail .bar .on .the .telescope .tube .into .the .
slot .of .the .mounting .platform .and .tighten .the .locking .knob .The .fork .arm .should .be .at .the .right .side .of .the .
telescope .tube .when .the .telescope .tube .points .forward .(Figure .10)
Note: . . . You .must .be .careful .not .to .use .an .optical .tube .that .is .too .heavy .or .too .big .as .the .motor .assembly .will .
not .be .able .to .operate .properly .and .may .damage .the .mount .As .a .guideline, .do .not .use .tubes .that .
exceed .4 5 .lbs .(2 .kg)
.:. Figure 10 - Correct tube orientation
.:. Figure 11 - Installing the finderscope
5 . . For .observers .in .the .Northern .Hemisphere, .loosen .the .azimuth .and .altitude .clutch .knobs .and .move .the .
telescope . to . center . Polaris . (the . North . Star) . in . the . field . of . view . When . it . is . centered, . lock . both . of . the .
clutches .For .observers .in .the .Southern .Hemisphere, .center .the .scope .on .Sigma .Octanis .(near .the .South .
Celestial .Pole)
6 .Verify .that .the .clutches .are .locked .and .the .power .to .the .mount .is .switched .off
Note: . . . After .completing .step .6, .the .mount .is .not .in .its .proper ."Power-On" .position .Always .place .
the .telescope .in .this .position .before .you .turn .on .the .power
2 . . Using .the .bubble .level .built .into .the .base, .adjust .two .of .
the .feet .to .level .the .mount
3 .Install .the .finderscope .bracket .on .the .optical .tube:
. a . . Loosen . the . two . silver . setscrews . located . on . the .
base .of .the .bracket .
b . . Slide .the .bracket .over .the .dovetail .bar .attached .to .
the . tube . and . tighten . the . two . silver . setscrews . to .
secure .it .in .place . .
c . . Insert .the .5x24 .finderscope .into .the .bracket: .slide .
the .eyepiece .end .through .the .rings .of .the .bracket .
so .the .eyepiece .end .of .the .finderscope .is .closest .
to . t he . r ing . w ith . t he . t hree . b lack . a djustment . s crews .
(Figure .11)
d . . Adjust . t he . t hree . b lack . s crews . u ntil . t he . fi nderscope .
is .held .securely .in .place
4 .Align .the .finderscope .with .the .main .optical .tube
a . Insert .the .star .diagonal .and .25 .mm .eyepiece .into .
the . back . of . the . scope . and . secure . them . with . the . .
silver .setscrews .
b . . Loosen . the . altitude . and . azimuth . clutches . and . .
rotate .the .telescope .to .locate .a .distant .object .on .
the . ground . It . should . be . at . least . a . quarter . mile .
away .for .best .results .Once .centered, .tighten .both .
clutches
c . . Focus .the .finderscope .by .turning .the .eyepiece .of .
the .finder
d . . Using . the . three . black . setscrews . on . the . finder .
bracket, .loosen .and .tighten .them .until .the .cross-
hair .in .the .finderscope .lie .on .top .of .the .object .that .
is .centered .in .field .of .view .of .the .25 .mm .eyepiece .
in .the .main .telescope
e . . Verify .that .all .three .of .the .setscrews .are .snug, .but .
do .not .over-tighten
