GTD Integra85 Focusing Rotator

Features

The Integra 85 is a focusing rotator. It has a clear aperture of 85 mm, a backfocus of 69 mm, and a travel of 10 mm. The focusing function of the Integra85 is based on 3 fine pitch leadscrews running in special low friction nuts that provide high loading capacity up to 8 kg with a travel of 10 mm in 188600 0.05 micron steps. The rotator is using a traditional wormwheel, the 360 degrees is divided up in 61802 steps. The focuser has an autocalibration feature.

Main Control tab

• Direction: Focus IN or Focus OUT. IN decreases ticks count, OUT increases ticks count.
• Relative Position: Set the number of steps from the current absolute position to move.
• Absolute Position: Set the number of absolute steps.
• Abort Motion: Stop any focus motor movement.
• Sensors: Reading of the focuser temperature sensor.

Presets tab

You may set pre-defined presets for common focuser positions in the Presets tab.

• Preset Positions: You may set up to 3 preset positions. When you make a change, the new values will be saved in the driver's configuration file and are loaded automatically in subsequent uses.
• Preset GOTO: Click any preset to go to that position

Settings tab

• Max position: The focuser and rotator maximum travel in steps.
• Home at Center: This autocalibrates the focuser using a homing sensor and places the focuser in the center position at 94300 steps.

Rotator tab

The rotator position can be controlled via either setting the absolute ticks count or angle. To change the current absolute position to a new position without moving the rotator, use Sync to set the new desired position. Once Sync is set, the current absolute position shall report the synced ticks.

• Goto (Angle): Rotate to the specified angle.
• Abort Motion: Stop any rotator motor movement.
• Sync: Synchronise the current position as the specified angle.
• Reverse: Reverse angle direction.
• Goto (Ticks): Rotate to the specified tick count.
