This afternoon I just finished pulling my whole focuser apart (I took the focuser off the OTA to make it easier) and putting it back together again, as per the instructions above. All I can say it wow! It has made a huge difference. Its not silky smooth, but it is a big improvement over what it was like before. Before the end of the weekend I hope to have the secondary checked (thanks for the howto!) and centered, and the focuser put back square again.
Some notes:
- when people say the factory "grease" is sticky, they arent lying. The stuff is literally like glue, I had to wash my hands 50 times to get it off my fingers before trying to clean another part. The isopropyl alcohol I used worked well, the earbuds I used to clean the focuser with were a pain though, they kept leaving little bits behind stuck to the glue. It all up took over an hour to get the glue off, but even then I dont think its 100% out. I ended up using the silicon spray, I sprayed it onto an ear bud before applying it, and then wiped off any excess.
- either my focuser is missing parts, or the design has changed a little bit from the pics on the website. My focuser did not have the metal retaining clip, and also had teflon sliders instead of the plastic strip, and there was no allen key screws on the side of it. It has the holes, but they are filled in.
It was definitely worth the time, and if I dont end up with a craford focuser soon I'm going to have another go at getting the glue out.
