0x8 Reducer/Flattener Recomendation

[astro mick]

Looking for a 0x8 Reducer/Flattener for my Celestron 80ED F7.5 Scope.

Recomendations please.

Mick.

I'd like to hear recommendations too. Here are the options I know about:

Orion (US) 0.85x reducer/flattener:

- Appears to work very well

- No longer offered by Orion

Skywatcher 0.85x and Vixen 0.85x

- appears to be the same as the Orion 0.85x FR/FF

WO 0.8x Type II

- Good reviews

- Type II no longer offered by WO

Televue TRF-2008

- Good reviews

- Recommended by Orion staff for the ED80 (they now carry the TRF-2008)

Orion 0.8x reducer

- Reduces but does not flatten

- Should work for small sensors, but edges of APS-C will have problems

Orion flattener for short refractors

- Appears to do a good job flattening, but no reduction

- See astrobin for examples

- I ordered this flattener because of the low price, but if price is not an issue for you then I think the 0.85x FR/FFs would work better.

Hi Mick,

I have the skywatcher (UK) x0.85 FF/FR, which is dedicated to the ED80 scopes. Works extremely well

and creates a nice flat fields when you get your spacings to your ccd chip correct.

Mick,

I bought the Televue TRF-2008 for my Skywatcher Equinox F6.2 ED80. Very pleased with it.
