Outstanding
Alan McLaughlin
This is an amazing unit. Well done on engineering and design
Fernando del Olmo
I thought was well designed, quality material and good program, looking forward to give more details. Oregon the weather is like one minute is raining the next is work and sunny. The coast in the summer we have spots real black no lights pollution.
Jens Hackmann
A perfect piece of technique, built very worthy and my first results were very good. Up to five minutes exposure time with almost no pixel movement between the frames promise to be the tracker a very nice and useful longtime accompaniment for night time shots.
K Rieke
Excellent star tracker, proved itself when my 500mm lens was mounted and I achieved sharp round stars with long exposure. I wish you would include two more QR plates to attach more components (such as I will use Z+ and 2 axis pan/tilt plus ball head, but I can only QR plate one of these. If I had more plates, swapping heads would be simple when I want to use or not use the tracker. Better English documentation about errors and warnings also would be nice, and no AI slop images in your manual. One tutorial switches azimuth and elevation accidentally, but the astute user understands the intent. Great product, build more community around it.
