Field flattener/ focal reducer

[decoyp]

Can anyone advise me on a decent field flattener or focal reducer (is it the same thing) to use with a Equinox 80ED. I' ve seen a dedicated one from skywatcher for this scope but have also read that it can take focal reducers used on SCT telescopes. Which ones ? I would prefer a 2" version funds permitting.

Thanks in anticipation

Hi Richard,

I use a Televue TRF-2008 as when I researched it I was told by many respected imagers it was the best one to use. They weren't wrong, it gives fantastic results although it is quite expensive.

I'm on my phone at the moment, but when I get home I will post up an analysis of one of my subs from my QHY8 and you can see how flat the field is.

Thanks
