William Optics reducer.


Recommended Posts

Hi.

I have a celestron ED80 F7.5 refractor that i am using for imaging,using an MX916 ccd camera.

I was wondering if it would benifit from a reducer.Would i get a wider field of view,shorter exposure times.

I was looking at the new William Optics 0.8x Reducer Flattener 111.

Any comments.

Mick.

Hi Mick,

I'm on the same learning curve as you as far as reducers/flatteners are concerned.

I had a long conversation with Ian King on Friday, at his home, where I picked up a

new Megrez 72. The one issue that came up, no matter what flattener you get, is

that they require very careful adjustement in obtaining the correct chip to focus point. I'ts not just a case of placing the flattener in the draw tube, attaching the

camera, focusing and away you go. I would suggest you talk to Ian King and discuss

your requiements with him. I'm sure he'll be able to answer all your questions.

He is very knowledgable, and a very nice bloke as well.

It may just save you a lot of hassle.

Regards,

Yes. A reducer effectively reduces the focal length (the opposite to a barlow) which increases the field of view and lessens the focal ratio which makes the scope faster.
