Hi Guys,
Up for grabs is a TeleVue TRF-2008, 0.8x Reducer Flattener for 400mm to 600mm Refractors. Bintel price is $469 yours for $250 plus postage.
More info about it at :

It works well on 80mm ED refractors giving a slightly wider, flat field which is what you need for Astrophotography.
Some test have been done on conventional SCT with good results see the following link:

I have never tried it on a SCT so can't verify the above.
It has only been used a couple of times and is in pristine condition.
Cheers
Peter
