Mystery 2" diagonal

[nightfisher]

Can any one identify the make of this 2" diagonal, it is CNC machined and has a mirror quality of 1/8 with compression ring on the 2" barrel and low profile 1.25 adaptor, i bought it from Astroboot and it arrived in a plain black box with no makers tags to be seen any where

Probably some generic PRC diagonals they never got round to badging up and have just found in the back of the cupboard ...

I've been looking at those for some time on Astroboot Jules - I'll be interested to see how it performs

It looks well made for the price asked. The nearest I've seen to it is the TS one:

But it's not exactly the same.

Only one I can remember having a black annodised nosepiece is one offered for sale by Bill Vorce over on his ebay.com store. Don't know if it's an exact match?

And 10% of the price, cheaper than a stock skywatcher and much better quality

At that price, it seems too good to ignore, so I bought one too!

Im sure you will be pleasantly pleased with it, the whole thing just oozes quality

How is it for collimation?

It may be lazy, but I like a diagonal per scope. The ES diagonal with the 80mm Apo is spot on - turn the diagonal in the focuser (in that and the AR127L) and the laser spot barely moves on the front element. The Bresser 2" diagonal results in a spot that wanders like it is drunk. Of course, the well-performing ES is adjustable, but doesn't need it and the Bresser is the opposite.

At £30, this seems worth a punt to partner a £250 scope.

I cant say as i dont have a laser, it looks like it can be collimated though as it has a removable back, just like my Tal one 

[russ.will]

Mine turned up today. A very nice, solid lump of diagonal it is too. I especially like the low profile 1.25-2" adaptor. I'll investigate collimation tomorrow, as it's not quite there.

Of course, it's blowing an absolutely hooley at the mo, although I'm pretty sure that it'll look pretty much like any other diagonal. Mind you, for £30, it's a steal in material terms alone.
