Skywatcher PS Align Pro Phone adapter

thingiverse

This adapter lets you use your PS Align Pro app on your phone with your skywatcher star tracker while keeping your camera attached to it. That way, you won't have to take off the device and reattach your camera, which can knock the tracker out of alignment and cause delays. Most phones should fit easily, but don't forget to buy a 1/4" screw adapter so you can attach your camera securely (as shown in the pictures). You can find this adapter on eBay at https://www.ebay.co.uk/itm/Centechia-Camera-Tripod-Captive-1-4-Inch-Folding-D-Ring-Adapter-Screw-In-OQ/264571110226?hash=item3d99aac352:g:reoAAOSwoahcpbz8. Print the adapter with supports enabled, especially for the dovetail and camera mount section. Filling in this area at 50% should give you a strong enough design. You can attach the adapter either in front of or behind your camera, depending on how you're using it - either way works well.
