skywatcher 0.85 reducer for 80ed and filter fitting

[andyo]

Hi,

wondering if anyone can help,I recently purchased a stripped down version of a SW80 ed and I am going to get the reducer to go with it (thats the Skywatcher 0.85x

reducer).I use a canon 450dslr and presently have a 2" nosepeice to which i attach a 2" baader neodynium filter.The question is how do you attach filters such as these when using the reducer

[sloz1664]

The 2" filter fits the rear threads of the reducer. There is also a dedicated canon adaptor that fits the reducer , but I don't

know how inserting a filter in between the canon adaptor & reducer would affect the 55mm spacing necessary to create the

ideal flat field. I have a dedicated CCD with the same neodynium filter and have spaced accordingly.

cheers

Steve

You'll probably need a DSLR - M48 adapter to attach to the camera and reducer then there is a FLO adapter http://www.firstlightoptics.com/adaptors/flo-adapter-for-skywatcher-focal-reducers.html this sits inside the ED80 focusser tube. You mount the LP filter on the end of this adapter.

Thanks Steve thanks Simon.Yes I need a m48 canon adapter to go with the reducer so I think it would affect it by altering the spacing Steve, would probably need the adapter suggested by Simon had a feeling it would involve spending more money lol.
