I'll consider the Tak LE's also, thanks for the info Don and Mike! They maybe cheaper than the Radians on the used market. I remember using a 4mm Radian in a...

Hello, I'm new to the group and will soon be an owner of a Discovery 17.5 f/5 TD. I was looking for some HONEST feedback on this scope. I've seen Ken's ...
Hi, I bought a 12.5" PDHQ about a year ago and my widest true field EP is a 32mm Plössl Meade, wich gives true field of 1.04°. I'm thinking about buying a 2"...
Both reach focus in my 12.5" truss dob. I presume the focal ratio, secondary size, and focuser are the same. So they will both likely reach focus for you,...
Cooling of the mirror is a bigger problem than light in from the back. It does depend on how close the mirror is to the end of the tube, but the secondary will...
Hello I have the 17.5"f/5 Discovery split tube. Discovery optics are very under rated and you can't beat the price! I would only change from the split tube ...

Rui, Don't worry about the exit pupil. 1) I'm 54, and only have a 4.5mm dark-adapted pupil, yet I can use the 35 Pan because the secondary isn't noticeable. I...
Don As with my 20mm T/2, using the paracorr to me is not needed. Both are sharp to the edge of field, it may be the extra mag that seem to give a better view ...
