I am new to this forum. I recently completed this rebuild of a 12 inch reflector telescope. One of my hobbies is astronomy. Also building these scope and accessories.

It is built from birch ply, aluminium, and some purchased accessories. I have plenty more pics of this build here.

Followed the standards set in the Kriege & Berry design. Sort of. I deviated some on the upper assembly and mirror cell.

I am from the West side of LA around Lake Charles.

I guess I should explain why I did this. Main reason is portability. The original scope was a solid steel tube on a particle board base. It was very awkward to transport to a darker observing site. The old tube was 50+ inches long.

The new scope weighs around 75lbs fully assembled. About the same as before but it can be broken down and is more manageable.

This type of scope is a truss dobsonian reflector design. You do not have to have a scope to start with. You can simply purchase the 2 mirrors and scratch build everything else.

Just a little background for those that have not seen this before. THX.

Awesome. Looks very nice and portable. I also enjoy astronomy and appreciate the efforts that go into making big scopes portable.

Thanks Geoff. They are very fun to make and it performs much better than before. It only takes about 5-10mins to setup and it fits in my small truck or car. That’s including collimation.

Have your say...
