slewing .rate .selected; .the .slower .the .slewing .rate .the .longer .it .will .take .for .the .star .to .appear .to .move .
in .the .eyepiece. .Therefore, .the .anti-backlash .compensation .will .have .to .be .set .higher. .You .will .need .to .
experiment .with .different .values; .a .value .between .20 .and .50 .is .usually .best .for .most .visual .observing, .
whereas . a . higher . value . may . be . necessary . for . photographic . guiding. . Positive . backlash . compensation .
is . applied . when . the . mount . changes . its . direction . of . movement . from . backwards . to . forwards. . Similarly, .
negative . backlash . compensation . is . applied . when . the . mount . changes . its . direction . of . movement . from .
forwards .to .backwards. .When .tracking .is .enabled, .the .mount .will .be .moving .in .one .or .both .axes .in .either .
the . positive . or . negative . direction, . so . backlash . compensation . will . always . be . applied . when . a . direction .
button .is .released .and .the .direction .moved .is .opposite .to .the .direction .of .travel.
To .set .the .anti-backlash .value, .scroll .down .to .the .anti-backlash .option .and .press .ENTER. .Enter .a .value .
from . 0-100 . for . both . azimuth . and . altitude . directions . and . press . ENTER . after . each . one . to . save . these .
values. . SynScan
. will . remember . these . values . and . use . them . each . time . it . is . turned . on . until . they . are .
changed.
Slew Limits – . S ets . t he . l imits . i n . a ltitude . t hat . t he . t elescope . c an . s lew . w ithout . d isplaying . a . w arning . m essage. .
The .slew .limits .prevent .the .telescope .tube .from .slewing .to .an .object .below .the .horizon .or .slewing .to .an .
object .that .is .high .enough .that .the .tube .might .hit .one .of .the .tripod .legs. .However, .the .slew .limits .can .be .
customized .depending .on .your .needs. .For .example, .if .you .would .like .to .slew .to .an .object .that .is .close .to .
the .zenith .and .are .certain .that .the .tube .will .not .hit .the .tripod .legs, .you .can .set .the .slew .limits .to .90º .in .
altitude. .This .will .allow .the .telescope .to .slew .to .any .object .above .the .horizon .without .warning.
Filter Limits . – . When . an . alignment . is . complete, . the . SynScan
objects .are .above .the .horizon. .As .a .result, .when .scrolling .through .the .database .lists .(or .selecting .the .
Tour .function), .the .SynScan
horizon .when .you .are .observing. .You .can .customize .the .object .database .by .selecting .altitude .limits .that .
are .appropriate .for .your .location .and .situation. .For .example, .if .you .are .observing .from .a .mountainous .
location .where .the .horizon .is .partially .obscured, .you .can .set .your .minimum .altitude .limit .to .read .+20º. .
This .will .make .sure .that .the .hand .control .only .displays .objects .that .are .higher .in .altitude .than .20º. .
If .you .want .to .explore .the .entire .object .database, .set .the .maximum .altitude .limit .to .90º .and .
OBSERVING
the .minimum .limit .to .–90º. .This .will .display .every .object .in .the .database .lists .regardless .of .
TIP!
whether .it .is .visible .in .the .sky .from .your .location .or .not. .
Direction Buttons . – . The . direction . a . star . moves . in . the . eyepiece . varies . depending . on . the . accessories .
being .used. .This .can .create .confusion .when .guiding .on .a .star .using .an .off-axis .guider .versus .a .straight .
through .guide .scope. .To .compensate .for .this, .the .direction .of .the .drive .control .keys .can .be .changed. .To .
reverse .the .button .logic .of .the .hand .control, .press .the .MENU .button .and .select .Direction .Buttons .from .
the .Utilities .menu. .Use .the .Up/Down .arrow .keys .(10) .to .select .either .the .Azimuth .buttons .(left .and .right) .
or .Altitude .buttons .(up .and .down) .and .press .ENTER. .Pressing .ENTER .again .will .reverse .the .direction .of .
the .hand .control .buttons .from .their .current .state. .Direction .Buttons .will .only .change .the .eyepiece .rates .
(rate .1-6) .and .will .not .affect .the .slew .rates .(rate .7-9). .
