FF/FR? to accompany new scope

[NickH]

New scope (TMB 105/F6.2), probably new camera...(secret!, but will be a large format..) heard that the Televue 0.8X FR is a good idea ..but anyone got any thoughts?

I have a TV reducer for scopes up to 800mm, I forget the number. I use it with my TMB which is 1200 and it seems ok. Backfocus for the reducer is 56mm. The camera end is a 'T' thread fitting so is no good for 35mm chipped cameras.

I use a Televue TRF2008 and it works reasonably well but I do get some vignetting with an APS-c sensor. I now have a WO TMB Flattener intended for the WO 110 and 132 you can get an adapter ring from Starlight Instruments. Hopefully this will provide a fully illuminated flat field for a full format sensor. The APM FF is around £900-1000 the WO flattner new and adapter is around £380.
