Tomorrow night, Tuesday 30th, is our next Advanced Astrophotography zoom meeting at 7:30 pm.
Using too thin or too long a cable to power your gear, can sometimes lead to random problems or equipment not working at all, even though it looks cabled and powered up.
I plan to demonstrate the voltage drop in the kinds of 12 volt DC cables that initially looked OK in the early days of my astrophotography journey.
Even just upgrading your cooled camera can turn a previously working setup into a problematic setup because of cabling.
Just using a couple of multimeters, you will see the difference you can make by just using thicker and shorter cables.
Having the correct power source that will last you all night is only part of the power puzzle.
Delivering enough current and voltage to your equipment for it to do its job is also needed.
