LACERTA MOTORFOCUS 21 2016
Tips for usage
For mobile astrophotographers we recommend to set the
StartPos
to a middle value,
and set the focuser to the approximate focus position before connecting. After
switching on start to measure the star profile, V-curve or use your Bahtinov mask to
achieve best focus. Set this position as
StartPos , and now you can switch on
TempComp and Backlash .
For permanently deployed telescope systems, use the stored position in MainMenu /
Handcontrol / StartSavedPos menu. You should always end of last observation
with GotoSelect / GoStartPos command to have this position ready.
Filter offsets : Mostly the filtersets aren't quite precisely homofocal, but near together
so you can build groups which are referred to the 4 availabe positions. Mostly, the
Lumi filter will be convenient to serve as a base and takes Filter 0 position. If you
change filter, choose the appropriate offset position.
If the focuser is oscillating, ignore the compensating to opposite direction of thermal
expansion trend in
MainMenu / TempTrack / TempTrackDir menu.
At the end of the work, mobile users can turn just off the device, stationary users
should go back to the
StartPos . Attention! Be aware that Manual turning of the
focuser is possible, but only if UTP cable to handbox is DISCONNECTED , otherwise
the possibly induced voltage may cause damage of MOTORFOCUS !
We wish you clear skies and great success using Lacerta Motorfocus !
