Losmany GM8 - Motors upgrade

Recommended Posts

Hi all,

This is my first post on this forum so I would like to say Hello. My name is Lucjan...

I'm Losmany GM-8 user with Digital Drive System and I would like to upgrade my mount to better system with new better accuracy motors.

Main mount usage is for astrophotography.

I have two options and I don't know what will be better for me (price is similar).

1. Losmandy Gemini 2 with servomotors and encoders.

- smoother (good enough?)

- faster than existing DDS

- many usefull futures

2. Avalon StarGo + stepper motors from Avalon

- stepper motors with microsteps

- Super fast with GoTo x800

- GoTo with BT smartphone

- extra ports for motors to focuser or filterwheel.

But as I say earlier - basic usage is astrophotography and I care about smooth and maximum precisely work. 

I like Gemini 2 with servomotrs but I have never seen how it works.

Thanks in advance.

I would like to examine just one aspect. What will be more accurate for astrophotography? Servomotors from Losmandy Gemini 2 or Stepper motors from Avalon with 1/72 microsteps drive?

Stepper motors from AVALON gives accuracy about 0.1 arc sec with combination with GM8 (G11 0.05 arc sec)

I don't know nothing about accuracy of Servomotors.

If its problems with astrophotography your having it might be a case of upgrading the ra worm which causes a lot of problems on the gm8
