An electric focuser makes it easier to fine tune your telescope's focus point, and is particularly noticed when viewing at higher magnifications. Without an electric focuser, it is often easy to pass right by the ideal focusing point.

No good for astronomy

Sturdy, well made. No good for astronomy. The smallest movement of the shaft is about 10 or 20 degrees, much too course for fin focus of my telescope. Way too course for astrophotography. Pushing the move button as lightly and quickly as I can, the focuser turned way too far.

Can this be used on the celestron astromaster 130 mm??? If not, is there any electronic focuser that can fit that telescope? or am I "SOL" =[
The Konus focuser is only compatible with a few specific Konus brand scopes. You can use this JMI focuser with your Celestron:
