Yes, agree re coating cost. probably the only other possible use for it is to attempt microflexing but would be a lot of pull and likely end up astigmatic.

I definitely won't spend on another mirror as house spending committee chair would veto/be cross. :-)

A new 8"f4 GSO is $219. I suggest you teach yourself mirror figuring on the Aldi mirror but don't re-aluminize it. Spend the re-coating budget on a new GSO mirror and use the change to buy some of the other bits and pieces then make him a telescope wrapped around a decent GSO optic.

Good luck whatever you do.
