The recomended collimation spring upgrade for the Meade 12" Lightbridge primary mirror is 'Century Springs / stainless steel compression spring code S-436'. Although you can order these directly from the US via
http://www.centuryspring.com/
there is a minimum purchase order of $40.00
US ($48 AUS) + postage + time!
I ordered mine through 'Bunnings special order service' and that took 4 weeks!
I have 3 springs left over at $12.00 each.
Therefore I'm asking
$36.00 + postage for the set of 3 springs.
PM if interested.
