Nicely made counterweight bar, purchased for my AM5N

A plug for B&H

When specialized astronomy gear retailers run out of some popular items (like this bar) check out B&H. They are more likely to have them. I also bought the main item, the ZWO AM5N, from B&H when it was running low in other places. AND I paid no tax.

See any errors on this page?

Does this also fit the am 5n mount?
