Im sure this will sound like a dumb question to those in the know. What do you use a really fast refractor for? 6" F/1.25!!! astrophotography or visual? is this useless? do you need a paracorr like in fast newts? Thanks Cam
The gist of it is that there's actually 6 or so lens components and it won't work properly without the others. Sadly it's worth avoiding. However check out the images taken at the end of the CN thread. It's pretty impressive when all together.
