Quote:Here's another for new Z owners:Several have posted having problems bringing their 30mm eyepiece that comes with the scope into proper focus. The common complaint is that there is not enough "out-focus" travel. This is most often heard about the Z8 model.There's a simple fix for this. On the front of the focuser are two thumbscrews. The upper screw controls tension for the crayford focuser. But the lower screw is a focus lock, useful for astrophotography, but not much needed on a dob used for visual.The problem is, that lower screw keeps the focuser drawtube from extending all the way. The solution is to loosen the screw several turns (or remove it if you wish), which will let your focuser extend an additional 1/4" and bring your 2" eyepiece to focus.Clear skies!
Quote:1) Laser collimator collimation. It's easy to check and adjust....I taped a piece of paper to the wall and marked 3 positions, with each of the adjustment screws pointing up. This made it easy to figure out which screw(s) to turn.
Quote: Gave the Dub Dob (I like that) it's first field test tonite. 8F ... perfect viewing weather! Clear sky anyway. Gives new meaning to the phrase "crisp air". Set it up about an hour before sunset, then went out to play. Jupiter was an easy target, so I used that to align the finders with the OTA. That Telrad is sweet for quick 'n dirty! I could see Uranus, but wasn't getting any decent detail, so I'm gonna have another go at fine tuning the mirrors. Wasn't too long after sunset, so I still had quite a bit of heat distortion to deal with. I'm happy enough that I could see anything at all first time out. Speaking of first time out ...

Quote:Good job Tom. Those springs sure do look much more substantial and functional. Is the spring pictured on the right already cut down?

Quote:I got tired of dealing with the RA finder so I made a wooden base for my Telrad and carved it to fit the dovetail mount for the RA finder. Then I angled the top of the wooden base with planes and chisels to match the plastic base of the Telrad. Screwed it down and voila! A perfect fit.
