Quote:Seibert sells a two-part optical set of lenses that he promotes as giving .93x with no in-travel requirement.It appears that there are two lenses. The first screws into the front of a standard 2" diagonal using the filter threads. The second part appears to go into the eyepeice holder, and I would assume that the binoviewwer with a 1.25" nose is inserted into the top of the diagonal.Anyone here tried this setup yet?

Quote:Initial impression is not very positive.Of course I wanted them for low powers in my 6" APO, but when I used eyepeices with a 27mm field stop, there was bad vignetting with the relay lens close to the mirror, and when I put it at the other end, I could not reach focus.I have not given up on it yet, but if I have to use a higher power eyepiece to eliminate the vignetting, then I would have been better off with the 1.5x GPC and a pair of Maxbrights.Again, have not given up. I will contact Seibert and see if I am doing something wrong, but for now, I have my reservations that it will work out.
Quote:Also, for anyone that is interested, this can be used with the Baader T2 diagonal if you order a special connector.
