“An awesome piece of gear made by an astrophotographer for astrophotographers. Fully ASCOM ready and custom 3D printed mounting platform”

“New autofocuser from on my new TS 60 APO. Perfect fit, all i need is a #clearsky.”

“Deepskydad ascom motofocus made by my friend It’s an overkill unit for the price and works flawlessly even in low temperatures.”

“This product is 100% plug-and-play. I copied the suggested settings in SGP and on the very first test run I achieved perfect focus (confirmed with a bahtinov mask). Pavle also worked with me to custom design a mounting plate that seamlessly fit upon arrival. It really is an astrophotographer's dream! ”

“Fantastic, simple to use design, plug and play. Customer support is excellent with regular updates on the build of your custom unit.”

“I was able to collect approximately 40 hrs of exposures and still got enough sleep. I recommended your focuser on local astronomy forum.”

The story

Astrophotography can be expensive. You start small, but quickly want upgrade your gear or add new type of item to the setup. Sooner or later you reach a point, where you want to automatize the process with a proper sequencing engine like SGPro for example. For me, that happend when I needed an autofocuser. Since I already wrote a few ASCOM drivers and have basic soldering skills, I decided to make my own budget version of autofocuser.

And so Deep Sky Dad Autofocuser was born! Little ASCOM supported autofocuser box with everything you need for pinpoint stars! Each unit was thoroughly tested in SGPro - be sure to check out our quick tutorial. If you are tempted to make your own, I have written our development procedure.
