servicing a Lomo Astele - need help!

Hello,

I recently acquired a Lomo Astele 133.5 Mak and am embarking on a learning experience of disassembling/cleaning/collimating. I've looked for info on these scopes online, but have only found a few threads.

Does anyone know a good/knowledgeable resource on these scopes?

My first question popped up after took off the back cover to reveal the collimation screws. There are three sets of two - one round-head screw which appears to be bottomed out and painted over, and another which looks like it's had some use. Are one of these a push/pull for adjustment and the other a mounting screw? Doesn't seem to allow for "locking" the collimation. Does anyone know how to use these screws?

Thank you,

-Jeremy

Jeremy,

Like you, I can only guess. All the mirror cells I've seen have one set of screws for actually adjusting the collimation and another set for pushing against the tip-tilt plate to "lock" the mirror position and hold collimation. Guessing again, I'd say the set of screws that feel "bottomed out" to you are the locking bolts and the other set is for adjusting collimation by tipping the primary mirror. You'll only be able to tell for sure by getting a drawing of the scope or taking it apart.

Thank you both. It looks like I won't be moving forward with this project, but I'm sure info will come in handy on future scopes.
