Hi Colin


It's alot cheaper, and you don't need to dedicate it to the scope.

I suppose - but I always loved gadgets of any sort, one reason why the
whole scope thing appeals so much ! You're right though, no real need
for a compass, and any cheap level will do the job.

I've been working on it this weekend. Just need to get the battery voltage
monitor circuit working. Then build a box to house the battery and circuits.
Here's a sneak preview of some of the work so far...
The clear blue box shows the insides of the box really well.
It certainly does - that is looking pretty damn cool ! I like the way
you are doing this, it is giving me a lot of ideas for power. I'd like
to build a combination battery box including your dew heater design and
also a mains inverter for the laptop when I get it up and running. I'd
like to include a charge indicator so I look forward to seeing how yours
works out, also might include the obligatory red light, and a built in
mains charger. I hadn't thought of using a breakout box mounted on the
scope to stop trailing wires though - great idea.

My immediate need is to not have to buy another set of those damn C
cells, so I think I'll pick up a small lead-acid battery and hook it up
as per your power cable specs, then think some more about my master
project. Do you know anywhere on the web that stocks a good range of
suitable batteries ? Chris mentioned he used an alarm battery from B&Q,
that will probably do for starters, but I can imagine I'll need
something fairly hefty when I get all of the above in and running !


Let me guess. The blinking lights. They're always popular.

Yep ;-) They look pretty simple to rustle up and would instantly label
me as a techno-geek. Is geekery possible in the telescope world ?


hehe yeah. And those long cloudy nights when there's no point settting up
the scope. Feel free to drop me an e-mail anytime.
Thanks - I had another look at the dew heater on your website today, I'm
definately tempted to give it a go !

I've just taken a quick look at your website. I can't wait to see the
images that you'll be producing with your Coolpix and Scope combined!

So much to do, so little time ... Yes, I need to source some kind of
mounting kit for that, but will probably try piggybacking first, and of
course there is the LPI to play with ..

Regards,

Andrew
