Rod,
Do not worry too much, we have all learnt a little along the way in the same way with this hobby
I think we put a lot of trust in our reputable retailers here is AU, but it does not always work out. Looks like they purchased a lot of mounts and forgot all about the tripods when they placed their order. They still want to move those mounts so recommended what looks to be the next best thing they stock. A shame really because from what I have seen it does not look like it would be up to the job.
For anyone looking for these Astro Anarchy in Brisbane is selling mount and tripod as a kit and also selling them as individual items.
