Thanks Phil.
I am hoping it will be an excellent instrument.
Here's a photo of the new observatory partially finished:

And here's one of the 2 slabs. The smaller slab is 1 metre deep and full of steel reinforcing and is for a Sirius Pier and Paramount ME and the CDK17. The larger 2m x 2m x 140mm deep slab is for my usual setup of a Tak NJP mount and either a TEC180fl, AP140 or FSQ106ED on a portable pier

I intend putting pavers on the floor around the slabs like I have at my dark site observatory (this area has quite dark skies , but my dark site has almost completely dark skies but its 4 hours drive away and I can't always go down there).
Greg.
