I am just three months into owning a 2003 Meade 8” XL200GPS scope. I have been pretty dissatisfied with the experience of focusing. I installed the Peterson EZ Focus which helped some but the image shift is still really annoying. The Meade Microfocuser with which it is equipped, even with its fastest rate is painfully slow and doesn’t let one focus back and forth to quickly zero in on best focus as you would with a knob. And if the seeing is poor, which it often is where I live than it’s even more frustrating. Use of a Bahtinov Mask helps.
So I am exploring possibilities for improvement.
Is there an easy hack to speed up the microfocuser?
Or, I may replace the microfocuser with a manual one. One of my considerations would be its length relative to the scope still being able to point strait up and also still fitting the scope in its case. Cost and single or dual focus would be others as well as smoothness and weight handling capacity. I am currently looking at the Antares 2” Low Profile Focuser – Dual Speed (at around $250). The height is just 5mm more than the Meade focuser. Also, the JMI EV-2C focuser (at $260). I don’t know the height yet. No one lists it … I’ll call them tomorrow. The focusers around $500 are out of my range. I did research the GSO 2” Crayford focuser. A good deal at $125 but reviewers had some troubles with heavier eyepiece/diagonal loads causing the focus to slip. Also, it’s longer than the Antares. I haven’t been able to find any reviews of the Antares and JMI focusers.
I am currently just observing but may move into astrophotography at some point so a focuser that can handle some weight would seem prudent.
I am definitely a newbie at all this and would really appreciate some advice and sharing of experience!
