Following Dr. Palmer's easy instructions had the equipment ready to go in no time. Connection to the ALPACA wifi driver was trivially easy, and for the longest time, I thought I was doing something wrong because I was expecting it to fail. Or, at least, to be more complicated. It wasn't.

Wow Eric. You can't imagine my happiness about reading this review.

 

I am right now in the process of buying a Nikkor 500mm F8 mirror lense as I thought that it could be a good lense for astrophotography. As you mentioned above, focusing with these lenses is not easy and there is a very narrow space to get it right.

 

I was not aware that an autofocuser could be used with a camera lense. Thank you for opening me a new area!

Glad I could help!! Clear skies!

The ability to manually focus using those two knobs to disengage momentarily is an excellent feature I miss after having to go with ZWO eaf and asiair. I had a Rigel n step focuser a few years ago and miss it

It's never too late to go back!!!  I use Pegasus Focus Cubes on a couple refractors and it just seems crazy to spend another $75 or so for a hand controller to be able to change the focus without a computer.  I'm in the process of 3D printing a differential slip mechanism that will let me change the focus without disengaging the motor, but yes, the Rigel Systems "red screws" are AWESOME!
