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.

Updated!  First Class PC Software & NINA Plugin

Run your unit with our desktop software or from NINA directly with our NINA plugin.

• Control your ASG EAT from any PC or within NINA's dockable window using our plugin.
• Configure orientation and help make adjustments easy and aligned with systems like ASTAP or Hocus Focus
• Automatic saving in case of power lose
• Firmware updating over the wire for easy future-proof design

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.

Player One & Moravian Octagonal Compatible 

Let us know if you run a Player One or Moravian Octagonal design and we can provide a special adapter to make it operate with this special unique body style.  We shorten the height of the cage and add 2 specially designed clamp rings to make it fit inside our cylindrical design.  This allows you to remove the 5mm tilt plate that comes with your Player One and delivers high precision tilt and backfocus adjustment where not present on their current design.

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.
