Alun,

[Mr Jack Martin]

Alun,

Thanks for the link and further info.

Shame that motor is a bit bulky, I assume you don’t have it permanently set up in an observatory.

Wouldn’t a bigger case be a cheaper option than another motor and having to replace what works ?

I see there are a few options from RVO to consider;

Please can you post a picture showing how and where the motor is attached / bolted to the Lhires.

How many holes did you have to drill ?

This is a worthwhile modification.

Thanks for your efforts.
