Field flattener/Reducer

[wsteel33]

Hi everyone.

I am looking to buy a field flattener/reducer for my scopes and would appreciate the advice and experience of you good people.

I have a couple of questions.

1. The scopes I am currently using are

• Skywatcher Evostar 120 (120mm f8.3 Achromat Refractor). https://www.firstlightoptics.com/evostar/skywatcher-evostar-120-ota.html
• Orion 80ED (80mm f/7.5 Apochromatic Refractor). https://www.telescope.com/Orion-ED80-80mm-f75-Apochromatic-Refractor-Telescope/p/9895.uts

Any advice on an appropriate field flattener/reducer for these scopes?

2. Would a single flattener work for both these scopes or would they need their own?

I mainly use the Orion for my photography of DSO so I would prob buy one for this scope first. I generally use the Skywatcher for planetary stuff and trying to image the smaller galaxy scale stuff.

Thanks in advance for your advice everyone and clear skies.

Unless we are talking very high specification specialist equipment I would always go with the matched focuser/reducer where available, thereby removing the possibility of mismatch problems.

Thanks

I have found one designed for the Orion 80ED 👍
