What you could buy is an inexpensive inverter which converts 12Volts DC into 110V 60Hz AC and run the scope from a "jump start" battery. The drive motors only draw 7 Watts for both, so the smallest inverter will work, but you might have to mail order it for the desired 110V 60Hz output.
If you find the orange drive corrector (fast slow box), those also took 12V DC input from a cigarette lighter plug and will run off a car battery or jump start battery.

..I've got a C8 from 1980 [bought at Celestron HQ!] but have never used the electric mains drive 'cos it's the wrong voltage for here in UK. How do I convert from scope's 110VAC 60Hz to 240VAC 50hz? I'd appreciate some practical advise.. I've still got [somewhere] the orange fast/slow box TIA.
If you've got the drive corrector, does it allow for 12VDC input? If so, there's your answer... if not, then I'd agree with the last poster. Your easiest route (especially for use in the field) is to find a drive corrector/inverter for 12VDC to 110VAC@60Hz. I believe you use the same kind of auto accessory plugs in the UK that we do here in the US...
Another possibility is to get some obliging soul here in the US to send you a 12VDC to 110VAC inverter. Very small ones around (~60W) are available here for US$20. You plug *that* into your 12VDC source and then your C8/drive corrector into it... and Bob's your Uncle.
