MK-67 focus question

Hi
I'm hoping someone can answer a question for me, I just acquired a MK-67 150/1500 and when I put a 2" to 1.25" adapter and 1.25" diagonal in the focuser, I had to hold the eyepieces I tried several inches above the diagonal to achieve focus. If I switch to a 2" diagonal can I expect 1.25" eyepieces with an adapter and 2" eyepieces to achieve focus or will an extension tube be necessary?
Thanks, Mark

Hi Mark I,m glad you asked that question. I just got a really nice Argonaut 150 Mak. I tried my Televues the other night on jupiter and I too had to pull the eyepieces up a bit to get focus and yet my Televue zoom worked fine.
Just wasn,t enough focas travel. I think the newer models have increased focus travel. Is yours a newer model. How are the optics on yours on the planets. Email me so we can compare. [email protected] Thanks, Dave
