I bought a used 2" Paracorr with tunable top. Unfortunately, I couldn't get anywhere near close to focusing. Need a lot more in-focus distance toward the secondary, I'm guessing at least another 1/2 inch. Up until now I have had no problems focusing with a variety of eyepieces.
Anybody else with this experience using a Paracorr? Did I do something wrong in using it?
My current focuser is the JMI DX3, relatively inexpensive and single speed. Is there a better brand that would allow more travel?
I'll try moving the primary mirror up too with the collimation bolts, but I've got a long way to go.
