[QUOTE=Tandum;477333]Thanks Greg,
If the extender is of similar quality to the tak, and that looks to be true, then I won't need my vc200l any more.
You may find it is better to use the FS102 for widefield imaging and get the F6 reducer for it. And use the VMC200L for longer focal length shots like galaxies where the FS102 will struggle no matter what you use as aperture ultimately rules.
The extender on the native F8 will give you F12.8 which is pretty slow for 102mm of aperture and will require a lot longer exposure times than your 200mm Vixen.
Greg.
