Burgess Optical 91 - Focal Reducer

[mickw]

Hi all,

I've got a Burgess Optical 91 f6.6 @ 600mm.

Any of you guys any suggestions for a focal reducer that works ?

Cheers

Mick

I think the skywatcher one would work or one of the william optics reducers.

Thanks for that, my only concern is a "flattener" seems optic specific and I don't want to make things worse.

The WO flattener IV is tempting as it's adjustable - but it's also 540 grams and over £200

The flattener are specific to the focal length of the scope, if you have a look at the specs it will usually mention it is suitable for e.g. scopes of between 500 and 700mm focal length.

Good point - I really should read the specs properly

Thanks

Mick
