The ASG Electronically Assisted Tilt (EAT) device provides a way to automate the the tilting and backfocus adjustments necessary for those fast scopes and round corner stars.  The ASG EAT provides a way motorized way to do full 4 corner movements within micron levels to precisely dial in the tilt, curvature, and plane of your camera sensor.  The ASG EAT also provides convenient backfocus adjustment to move in and out the sensor with precision.  Windows software is provides and the EAT plugins in with simple USB serial cable and 12v power supply, common on most power and mount systems.

Modular Design

The ASG EAT device comes compatible with many mounting options.  

• M54 female threads for threading directly.
• ASG 5 bolt pattern for our filter slider hardware.
• 62mm x 6 bolt pattern found on many electronic filter wheels.
• 99mm x 6 bolt pattern (4 provided) found on the ZWO 7x50 square filter wheel.

If not using these ports, we offer plugs and set screws to close holes you may not need!  Please note that if you use a 6 bolt EFW, it should have M2.5 screws with it and that are the correct lengths to adapt.  

ZWO 2600 Duo Compatibility included

Designed for any 90mm astro-camera such as the ASI and QHY cameras.  ASI cameras will mount directly, including ZWO 2600 duo camera with a notch for focusers.  QHY cameras also work well if the desiccant ports are removed and plugged with small set screws.  If its 90mm diameter, it will fit.  We can also provide adapters to make smaller cameras fit as well.

Tilt features

The ASG Electronically Assisted Tilt device is designed to provide precision tilting of the camera sensor in any angle from diagonal tilt to horizontal/vertical tilt.  The software provided allows you to do micron level tilting around 1 micron level to each corner or side.  The software will also handle opposing side movements, so backfocus is not changed during a tilt or alteration.  For example, if you tilt the left side or top side, it will automatically tilt the opposing side for you in sync.

Backfocus features

The software for the EAT device also allows you to do micron level backfocus adjustments at around 1.8 micron levels.  It will move all corners in the same direction with a range of around 1-2mm of overall movement.

Backfocus Required Spacing

The ASG EAT device takes physically 3mm of spacing.  We recommend you add +1mm to that for a total of 4mm as the optimal distance to accommodate the EAT device.  This +1mm gives you room to move the camera away 1mm and room to maneuver and tilt around, adjust backfocus, etc.  With a ZWO camera, you can remove the 5mm tilt plate on most 90mm cameras and replace with the ASG EAT device in that 4-5mm spacing range... but just make room for the 4mm is our recommendation.
