Very nice Pete.Always wondered how you would calculate the spacing of the secondary accurately. If anybody has tried to cut a circle in a sheet of plywood using a jigsaw they will understand how hard it is to get your apparently perfect circles! Respect!

There are some pre-existing finger prints on the mirror surface around the edge, fairly certain these won't have too much effect.
The only way to get rid of them is by recoating the mirror.

So finally got to the point of the first full assembly and, after making a clamp that will enable use with any mount that has a skywatcher / vixen dovetail, a focus check...

Collimation completed, here's the scope in use for the first time ( still need to fit a finder though)...

Picture of the moon through the scope - the camera was hand held so apologies for the blurry bits.

Seeing wasn't good and a fair bit of high cloud but the scope seemed to perform OK.
Would appreciate someone who uses a reflector having a look to give a second opinion though, hopefully on a better night.

...if we (the club) manage to get a reasonably priced EQ5 / CG5 it'll also fit on that.
