flattener position with filter wheel

[Joe]

Hi, I was recently looking into getting a filter wheel and reducer with my modded EOS 1200D, but im not sure how bad the vignetting will be in my images. The filter wheel will have to be 1.25" as I already have the filters (full narrowband set). I will be getting an altair astro 0.8 reducer, ZWO mini filter wheel and it will be attached to my Skywatcher evostar 80ED Refractor (f7.5). Any thoughts?

Inch and a quarter filters on a DSLR will give you a massive headache unless you can get them close to the chip. 

If you are going to use a filter wheel the filter will probably be too far away from the chip and will cause havoc with your edges.

You might get away with it if you can mount your T adapter straight onto the back of the filter wheel. 

Mind after all is said if the worst comes you can always crop down the pictures edges.

That was my plan. I was going to go scope ,reducer ,wheel ,t adaptor ,camera. If I crop the edgea I may as well not get the reducer

The reducer will still be a good idea.

It will definitely be a bonus in your imaging.
