ZWO camera focuser

thingiverse

Here's my spin on the text: I'm building a custom focuser for ZWO sky-cams that will take it to the next level one day. This is an initial experimental project that's getting off the ground. I've already printed two STL part-files, and they're looking promising. The first part fits snugly onto the ZWO camera lens itself, although it could use a bit of refinement for a tighter grip. It's held in place by friction alone. The second part is designed to cradle the ZWO camera body and stepper motor together. I'm using a stepper motor from eBay (https://ebay.to/2WYtGDV), which gets hot under heavy use, so I'll need to tweak the driver settings accordingly. Currently, I'm running with a compatible driver from eBay (https://ebay.to/2L8siYc) and some open-source Arduino software that's widely available online. If you've got any suggestions for improvement, now's the time - just remember to keep an eye on those temperatures! For practical use, it's likely best to set up the driver from Python on a Raspberry Pi to make things more user-friendly.
