Altair Astro 0.6X Refractor Reducer

I posted a query on this reducer some weeks back.

Does anyone have this reducer?

Also they are now back-ordered at most of the UK shops. And it seems nobody outside the UK sells them, not even the old standby Teleskop-Service.

It is considerably cheap enough that I'd buy one to try out, in spite of the paucity of reviews.

But I can't buy one... the UK retailers won't ship to a non-UK address.

Yes I have one. It works remarkably well for the price. Heres a picture I took recently with it. They work well on refractors of f7 and longer.

That is pretty good. Is that a full frame? What's the chip size? Looks like an 8300. What is the f ratio of your tube? I'm thinking of getting one for my AT90EDT (600mm fl, f6.7)

Its cropped very slightly as the reducer vignettes a little in the corners. It was taken with a DSLR. My scope is f7 native focal length but f4.2 with the reducer. Its funny you mentioned the 8300 as I think a 8300 chip would be nice, tempted by this myself at some point....

I tried one but couldn't achieve focus with my F6 Frac

I assume it requires significant in focus. Most / all reducers do. This would take my refractor down to f/4 which is pretty tempting.

Right now I'm using an f/4 Newtonian with the incredibly expensive ASA Keller reducer giving me f/3. But the collimation is an incredible pain in the behind and I still can't get round stars out of it. Pretty bad return for a $1000 reducer and $400+ Feathertouch focuser on a $400 Newtonian....

So if this thing delivers I'll be one stop slower but no collimation headaches...
