Hutech Hinode Solar Guider - worth it?

Hi all,

I’m thinking about purchasing the Hutech Hinode Solar Guider for use with an HEQ5 pro and AZ-EQ5. Is it worth it? Has anyone used it with the above Skywatcher mounts? Any tips, gotchas? Looks like it uses ST4. Any issues there? Also, looking to use it with Firecapture. 

Thanks in advance, 
Rob
