Yeah, I am in effect deep cycling my 7AH SLA in one session, which is not good. So I am after maybe 12AH or even 18 AH now, and I like the idea of a 'dedicated' powertank or jumper purely for the convenience (and gimmicks) of an all-in-one box. If I get a 12V jump starter - is connection directly to the jumper leads OK? Thanks, Fox.

Fox - a jumpstarter/powerpack from an automotive place will have a cigarette lighter socket on the side of the unit: it will also come with a lead with a ciggy plug on one end and a standard plug that should fit into your scope mount (at least it does for the HEQ5 Pro.)
As said before, just as long as your Meade mount runs off 12 volts and the central tip of the plug that goes into the mount is the correct polarity. All the jumpstarter/powerpacks I've looked at have a positve polarity centre tip, which conforms with the HEQ5 requirements. Just check these things re your Meade requirements.
This lead with the ciggy plug and mount plug doubles as a recharger for the powerpack when you've only got your car to recharge from (ie for when there's no mains around.) If the Meade requires a negative tip plug on the mount you can convert them with a simple electrical alteration - getting a new plug from Dick Smiths etc. Get at least a 17 Ah powerpack.
