If one has an eyepiece to reach a certain magnification I would guess they may not be likely to use a barlow, if they have one at all. I don't have one as it does not work with a Paracorr.




Steven:

I'm not sure why you say barlows won't work with a Paracorr adapter? I don't think there are any issues with combining them. I tend to use them separately because putting the two together represents a significant perpendicular stack. Adding a 2-inch Nagler on the end of that combo represents a serious collimation issue, IMHO. That's really the only reason I won't do it, honestly. I have combined them a few times just out of curiousity, and they seem to work fine together. Tele Vue even recommends a certain connection order. I don't recall if the Powermate/barlow is supposed to be inserted into the Paracorr or if it is the other way around. But the fact that Tele Vue even provides a recommended configuration suggests that they work together.
