Would it be worth getting a motor drive for my Meade Polaris Telescope?
A tracking motor is always handy when using higher powers with an EQ mount.
Only you can determine if it's worth it based on what you want to accomplish, finances, etc. RA motor drives are available on eBay for about $35-40 shipped. They come with a mounting bracket and hardware, use a 9V battery, and are pretty easy to install and use.
I mounted a Celestron branded motor on my CG-4 years ago and it works as well, if not better than the day I installed it. Because of the side I mounted it on, the motor direction switch is set to South instead of North to get the correct rotation. No big deal.
I made two mods to mine. Early on I found the 9V batteries varied speed as the night progressed. My solution was to solder a long 22ga twisted pair wire with a 9V battery snap on the end. I use a six AA battery holder that has 9V terminals. With the added capacity (amps) the motor speed is stable and the cells last for months with frequent use. The other mod I recently made was to the speed control shaft. It's skinny and somewhat hard at times to dial in the motor speed. I found a small grommet that I slipped on the shaft, and with the increased diameter I can dial in the tracking speed very precisely. I didn't feel a need for the larger diameter until I got into imaging deep space.
You can see the motor on the mount, as well as the battery holder held on the spreader tray with a Velcro strap.
