External power supply – Laser Collimator MK III

14 January 2022

The laser collimator is a very useful tool especially for amateur astronomers. My model ( Baader Laser Collimator Mark III ) works very well, but has one disadvantage, like any other type of this type. The weakest link in the whole construction is the SR battery model. Usually, the battery likes to fail when the collimator tool is most needed. The battery model is not very popular and, unfortunately, it is not the cheapest. So I’ve made an external power supply for Laser Collimator MK III.

SynScan GOTO v4 controller – trouble with buttons

At some point while using the controller, I noticed that the ESC button wasn’t always working. I lived with it, but after a while, the left Ra button also started acting up and wouldn’t always connect. A red flag went up in my head – something needed to be done. It’s worth noting that the problems appeared right after the warranty period ended… coincidence?

EQDIRect for NEQ / EQ mounts

The GOTO controller is extremely convenient and practical to use, when you want to look at interesting night sky objects, with your own eye through the eyepiece mounted in the telescope’s focuser. The ability to quickly select an object using the GOTO controller, is invaluable.
