My primary telescope is the ED-102 Triplet with a 714MM focal length and f/7 ratio with an apochromatic design for very low chromatic abberation. I chose this scope as my entrypoint into astrophotography because I was looking for something with broad usability (wide variety of target options), relatively forgiving of less-than-perfect tracking and moderately portable.
USB hub and Pegasus FocusCube
AVX hand controller and Pegasus Powerbox
Attached at the top is my auto-guider, a ZWO 60MM scope with the ASI 290MM mini guide camera.
On the main tube, I have heavy-duty adhesive velcro strips cut to size in between the OTA brackets that I use to attach the necessary electronics, including an Anker powered USB 3.0 hub, the Pegaus Powerbox, and my Celstron AVX hand controller. Also tucked away under the tube are a pair of sensors for humidity and temperature used by the dew controller and auto-focuser (Pegasus FocusCube) respectively. I then plug my USB hub into my laptop (currently a Surface Book) with an extra-long USB cable and control everything from there.
Everything is either powered from the Powerbox (minus my DSLR recently, as I’ve had issues with low voltage coming out of the powerbox when everything is running so plugging that in directly), or through the 5V USB. Only one data cable out and one power cable in are needed.
