I've tried this and it's a "no joy" scenario Excellent - could you perhaps advise on a particular model of Power Supply? I've no idea what I'm looking for.. That's interesting to note. Thank you

OK thanks, both In the manual for the device, it states I need a 12VDC750 mA (Tip Positive). I see on Amazon there's one with a reversible polarity, will I blow this up if I accidentally plug the tip in the wrong way? What about this one? I'm not sure which way this one has it's polarity though... Kasstino Power Supply Adapter 12V AC 100-240V To DC 12V 2A 24W

Hi Dave, Yeah - from word go it's always ran on just 1.2 rechargables without issue (aside from draining super-quick, my work around was just to have a stack charged ready). I don't have a PSU ready to go, but will be buying a 12v but at this time am unsure precisely what sort I should get (AC/DC?) and don't wish to blow it up...

I have the aforementioned telescope but not used it in several years. It's just been sat, quietly out of the way in a small cupboard (dry, dark, nothing amazing) but not stored in it's box as perhaps it could have been. Nonetheless, I went to take it out as a friend had asked me to take it to his for an evening's viewing pleasure. I tried the batteries I'd just bought (16xrechargables) but was unable to get any signs of life. Between myself and a friend who's somewhat more conversant with electricity than myself, we discovered so far that there's no signs anywhere of life from it - but we're not (as yet) sure whether it's a poor connection from the battery compartment or the switch. We do know the batteries are good. Any advice on narrowing down causes, please?
