Battery free electric focuser
I have made many to its design since I finished the new focuser mainly due to the fact it required more pressure to focus it the gears kept slipping.
the first change I made was to lower the height of the assembly on the telescope, this is easy to do with polymorph just cut it, heat it and stick it back together while its cooling smooth out edges so it looks nice :)
the reason for this is to allow it to sit closer to the tube as well as getting a better connection with the 2 gears
The other change I made was to place a small piece of that non slip matting that you can buy for like 99p under the focuser on the telescope as this stuff is spongy as I apply pressure with the belt it allows the assembly to sink down, it now does not move!!
I made a small cube of poly morph to sit under the servo, i did this because when i change from in focus to out focus the front section flexes to compensate this change in direction and occasionally slipping gears, I put some electrical tape on it so it wouldn't fall out.
I made a crude (very crude!) handle for the hand operated servo. It's basicly a section of cardboard tube with a slit cut in it, the servo is placed in the slit then taped in place, the whole thing is stuffed with tissue paper then a generous amount of electrical tape to seal it all in. i also changed the style of the handle to allow me to focus with greater ease.
I will be updating the mod page eventually :)
I also purchased some matt black vinyl sticker which I will use instead of the paint on the new focuser, so I will post when I have done the mod
