Quote:I just use mine in 1.25, but it's hard to reach focus, that's why I have a recessed adapt., with a standard 1.25 adapt. can't reach focus. this is a problem on my little 3" refractor, which needs much higher magnification.Bill

Quote:For those of you with the 2.25x barlow, I'm curious about the focusing issue (i sent this not to Bill, but now am asking others). I have the 8-24 mark 3 that I've used almost exclusively on my 12" dob, but earlier this year I moved to china for a couple years and didn't want to bring the dob, so I bought a 3" table top refractor (cheap, but easy to use for planets, doubles, moon, sun). It has a very short focal length (350 mm), so with the zoom at 8 mm, I still only get 43x power. I bought an OWL 3x barlow for it, but when I add the two, I can't focus (I need the combination to sit a little deeper in the focuser, it is just out of reach, which is why I asked the question about the recessed adapter).
So this is why I'm curious. One option is I can buy the 2.25 Baader zoom and see if that solves my problem (and then I have a usable zoom when I go home for my dob or an upgraded refractor), but I would hate to do that and find out that I have the same problem. My other option is just to buy a "cheap" 3.2mm ortho for the scope.
So for those of you using the baader barlow, are you having issues with focusing in certain scopes?
