Could this unit control a stepper motor used on a heavy duty telescope mount for star tracking? It would push/pull approx. 30 lbs.

This is a motor, not a controller. It is on or off. Not a stepper motor.

What attaches to the turning part?

The output shaft of these motors are a 6mm D-shaped shaft with a threaded hole. Unfortunately, I don't know the specification for the threaded hole in the shaft Instead, I used a small aluminum hub, also available here on Amazon: https://www.amazon.com/gp/product/B00B887FX8/ref=ppx_yo_dt_b_asin_title_o04_s03?ie=UTF8&psc=1 That hub comes as a set of 2, with set-screws, and a small Allen wrench, but no other hardware. For that hub, I needed to get some #4-40 machine screws. I used 3/8" machine screws for the thickness of the material I mounted to the hub so that the screws would not protrude through the hub and into the motor mount. There are other 6mm hubs available that should work just as well. However, I selected the one listed above because of positive reviews, and in particular, info indicating that this hub uses 2 set screws which makes it more secure. That info was accurate. And I've found that hub fits and works perfectly for my application. I hope this helped.

What is the ratio of input to output? I'm looking for 30:1 or 60:1

This motor has 1:40 ratio and 1:65 ratio. The 1:40 ratio is 210rpm and 1:65 ratio is 90rpm.

Is there a template available to build a mount?

Lowes has some metal L-brackets that fit the bolt pattern perfectly. Coupled with 3mm screws from Lowes, it mounts easily.

Excellent motors

Use these for 3D printed bullet feeders work great. There’s a paddle that’s printable rather then drilling a hole, and using a roll pin. Makes it easy to replace. And these motors definitely hold up. With 10k through the first it’s still running great!

Fairly powerful but much smaller than they appear online

These are fairly powerful, little, units. In fact, it almost worked for my project (To raise and lower my drill press table). I believe the metal gears and construction is pretty admirable - just not powerful enough for my needs. To use this for opening a cabinet lid or drawer, I believe would be excellent - especially with the small footprint. I'm saving up for a more powerful gear motor to do what I need. I'll save this for some, other, future project.
