I believe that's a 1.5. But that's the size you'll need

Good job man. I've done all my synta scope focusers as well that same way(minus the tube). I hope you do a play by play with the cg4 as you did here. Diving into my one and only mount to de-synta-glue it makes me a little nervous

Well I did it. The CG-4 is now cleaned. Like you, I was nervous too. Let me tell you it wasn't that bad. I took photos along the way. On a scale of 1-10, I would consider re-greasing the focuser a 3 and re-greasing the CG-4 mount a 5 in difficulty. Go for it :)

Most excellent photos and step by step.   Do you do this for a living?

When you finish your project I will refer others to this link. 

Many are curious about re-lubing the focuser.

 

BTW that knob on the top of the focuser controls the friction on the draw tube.

If it is too tight, the focusing action will be rough.  If it is too loose, the focuser may

not stay where you leave it with a heavier eyepiece.  There is a butter zone.

 

There is also a butter zone for that plate that goes over the pinon gear too.

This is the best Illustrated set of instructions I have come across on cloudy nights. Great job

Thank you, I have a Skywatcher 102/F5 and I think this part of the telescope is exactly the same. I had a lot of trouble with smoothing focusing. Could not fine adjust. Slightly frustrating on planets I was trying to see.

I ended up purchasing a 2 "GSO crayford and you will not believe how much a difference it makes.

Suggest you look into it if you have the funds.   So easy to install.

Looks very nice, however I think I will be upgrading my telescope at some point and I

don't want to upgrade this guy, unless you think it is really worth it? 

 

I bought my scope for $40 CAD.

Please tell me you got a equatorial mount included in that price.

Unfortunately not, just the alt+az mount it came stock with. Lots of rusty bolt/nuts and missing slow motion control cables.

 

I just bough another $50 70mm Skywatcher refractor off craigslist and robbed all the good parts off it and it's now mint!
