Fixing iOptron GEM28

Greasing my iOptron GEM28 Mount

During one of my astrophotography sessions, I realized that my GoTo mount was slipping gears once in a while, not too frequent but it had ruined a couple of my subs. These equatorial mounts are meant to be precise to oppose the rotation of the earth during Celestial captures by keeping the subject being captured in the center of the frame. 

I couldn't find anything specifically between the gear teeth or perhaps it was too small to even notice, so I decided to give the gear box a complete cleanup and re-grease them.  

I decided to open it up and grease it if required. The point is if there's a gear slip, I would guess there would be something perhaps as small as a dog hair or something that somehow managed to get in between the gears.

My subsequent star party captures were smooth, so what ever I did be it cleanup or re-greasing helped.
