Gday John, thats very interesting!! - and weird!! some sort of vortex developing
I think i will stick with the old fashioned cool down for now
- If i want a quick look I usually use the 8.3" takes no time at all to cool down - in fact sadly that is the scope i use the most these days - just get the 10" out on special occasions these days - which is a waste of course. I really really like Birds set up - but I subscribe to the KISS principal and I would probably only mess up using that system
plus I really HATE BATTERIES AND POWER SUPPLIES!! LOL
Cheers
Kearn
