3D printed autofocuser for my ES102.  No modifications on the telescope required, the autofocuser clamps around the base of the telescope above the drawtube. The focuser is driven by attaching the large gear wheel to the fine focus knob, by lightly clamping it down onto the knob itself with 3 screws.  No need to take the knob off and attaching it directly to the shaft. When the power to the NEM17 shortbody stepper motor is off, i.e. when the motor is not actually engaged in focusing, manual focus can be done by just turning the wheel. The main problem with the ES102 is that the drawtube is prone to slipping at high angles when a filter wheel and camera are attached.  While the motor has no problem lifting the weight, when the drawtube slips out of position the focuser has no idea how to recover.  To prevent the slippage, I installed 2 springs, one on either side, that take most of the weight of the EFW and the camera off the tube. 
  
 

I have recently upgraded my setup.

Gem 45
Edge 8HD
ZWO 294MC
ZWO 174MM Mini guide cam for Celestron OAG
Pegagus Ultimate PowerBox
RPi 4 with Stellarmate
Pegagsus Focus cube.
Dew Strips plus a heated dew shield when imaging.
Apple Airport express

All power from a single power supply providing power to the Ultimate PowerBox.
The RPi has a wired connection to an Airport Express.

I now run Kstars/ EKOS and Indi on the RPi. 

I can remove the losmandy plate on top of the scope and put it on my Esprit 100.

Mohamed - this is very good!
I wish I could put a thing like this in my yard but I can't - its' small and obscured by trees.
I keep my scope semi permanently on the garage roof - have to climb there every session to uncover/cover and turn on/off.

What's that thing on a tripod covered with snow?

A weather station?

Hi Max, It is my DIY Allsky camera
Its public link is allskycam.mhammady.info/01/

It helps me in planning (and weather)

No, it is my all-sky cam. My weather station is still WIP. didn't get enough free time lately
