[ATM] Secondary dillemma/Gel cell

["Tim Nott" <timothy.nott@ims.sa.edu.au>]

Thanks to those who gave suggestions about secondary size and batteries For my 16" Tri-dob.  I have decided that I will sleep better with a 3.1" secondary so I have ordered one from Astrosystems,  along with a holder and dew guard.  The shop I bought the other stuff from was happy to take the gear I already had back.  I also have bought 2 x 12V  2.2 amp battries that should run a computer fan for cooldown (0.19 Amps)  and dewguard (0.3 Amps maximum) easily for a full nights viewing.  I'll also have a toggle switch and plug so I can run it off the car battery just in case......

Cheers,
