Hope you don't mind me asking an "aside" question.

The power supplies I assume for scopes are regulated, I only take my car batteries and inverter to re-charge them, but......

How would you safeguard the 12v car power supply for the circuitry used in scopes.

Thanks

Most if not all scope electrics today will happily take up to 15 -18 volts without damage , a fully charged 12 volt battery is about 13.8v at its best dropping down to about 10.5v at its lowest .

The main thing is , is to keep them charged so they dont die from lack of use and charge , I charge my SCA pack about every 2 - 3 months .

Nothing to worry about mate .

Hi Jeremy
Maybe a fuse? 5 amp or 10 amp I expect.
Loving my focuser set up you inspired☺.
I tried to put a scope ring on my eq6 but it was a tad small so I tightened it and shattered the ring...so maybe yet another approach un the future with a ring made of ply or something.

Hi Brian
I think it is a good idea to charge them after a session to keep them topped up as batteries may last longer with that approach.
