I told myself I wouldn't sell this scope but I have to be realistic, it just never gets used.
I am the third owner of this scope, both previous owners are regular IIS members and they have looked after the scope extremely well.
I have lost my card-reader, so the photo's in the following links will have to do until I update.
**Note the dovetail plate in the first link is not included.

Case : High Quality Aluminum Case
Case Dimensions : (WxHxD) 59cm x 21cm x 18cm)
Case Weight : 3.8kg
**The lens cell has f6.9 engraved on it, however it was discovered that these versions of the M90 shipped with f6.2 lenses, I have confirmed this by aiming at the moon and measuring to the focal plane.
It does not affect the performance of the scope in any way other than providing a wider field.
The scope comes with:
WO hard case
WO 90mm tube rings (http://www.williamoptics.com/wo_shop/catalog/product_info.php?cPath=26_37&products_id=60)
I'm also including the following NEW unused items in original boxes:
WO 2" Extender tube (http://www.williamoptics.com/wo_shop/catalog/product_info.php?cPath=26_43&products_id=80)(US$41) for visual use, extends EP's to the focal plane,
WO 2" Photo adapter (http://www.williamoptics.com/wo_shop/catalog/product_info.php?cPath=26_43&products_id=79)(US$44) and
T-ring to suit Canon EOS camera or Olympus OM(4/3), your choice (~$10)
Idealy, photography should be done with a field flattener but the photo adapter will get you started.
$800
$700 firm *Sold*
I would prefer to sell localy(Perth) but may box it up if my arm is twisted enough, in which case buyer pays freight.
