It looks like it is the same grease mead uses. Post Extras:       imjeffp Aluminum Falcon Reged: 09/30/03 Loc: Cedar Park, Texas Re: Grease for LX200 baffle?

[Re: CORONA]       #5459528 - 10/07/12 04:20 PM Edit   Reply   Quote Quick Reply   Well I did go ahead and get the hi vacuum grease. I put it on the baffle tube and it did not change things much. I have always had a large amount of image shift (1/2 degree!), so it appeared that there was some other cause. I went back into the scope and removed the mirror assembly again. I observed that the metal assembly below the mirror (that is attached to the focus rod) was threaded on the shaft that slides onto the baffle tube. Above the mirror is a cork spacer, then more metal. The mirror seemed to be "loose" - the metal assembly below was not up tight against the mirror. I suspected that this gap caused the mirror to tilt. So I held onto the metal assembly below the mirror and rotated the shaft above the mirror to tighten everything down. The mirror no longer could shift, so I re-assembled everything back in the tube and checked it out. This turned out to be the problem - the image shift is very small, and the focuser knob turns very easily with no resistance. It had been harder to turn when the mirror was shifting in the loose assembly. The mirror did rotate some when I tightened it, so I was concerned that the rotational alignment between the primary and secondary/corrector was lost. But the images I see have shown there is no degradation. If it did degrade I would just rotate the corrector to maximize image quality. I have learned a lot from this exersize. Everything I have read about image shift referred to the grease issue - never have I seen comments about the mechanical assembly. If you are replacing the grease, you have the scope apart anyhow, and this is easy to check. Post Extras:       CORONA member Reged: 06/12/12 Re: Grease for LX200 baffle?

I got a tube of it and am thinking of removing all other greases and re-lubing with this stuff. Any ideas?

Does anyone know what grease will work and is safe to use in the Meade tube? Thanks. I have used SuperLube Synthetic grease mixed with a little Mobile One Synthetic SAE 40engine oil. It works very well because it can be mixed a bit thinner for us up here in the Minnesota Iowa area where actual temps can reach 30F Below actual temp. I have also used White P.A.O. Synthetic grease it neither thins or thickens but is expensive about $12.00 for 2 or 3 oz.. Post Extras:       Pages: 1
