Focal Reducers

[smr]

Hi,

I like the FOV I have with my scope, quite a widefield 430mm fov, which coupled with my 80D frames many targets quite nicely.

There are one or two targets where it'd be nice to go even wider though, and I was therefore wondering if there's the possibility of buying a focal reducer for my scope which would help achieve this ?

The scope is a Zenithstar 73, I have the dedicated Z73 1:1 Field Flattener for it too, so I was wondering if I could replace this with a focal reducer and change the FOV?

 

Thanks for any advice.

I use a TRF-2000 0.8xreducer with my APM 80mm F/6, and that works nicely. I have also been testing an Altair Astro 0.6x reducer, but that gives me some issues with star shapes at the edge of the FOV.

I'm testing my new 0.5x FR, for my 90 mm & 127 mm MAK-CASS' but it fogged up, with low 30s F temps. That's, with 2 dew heaters & now the weather is bad.
