How I can reduce a telescope to increase without changing the eye?

I have this telescope cheaper than I want to manipulate to increase their field of vision increase or decrease an electronic eye. Is there anything I can do with the primary mirror? companies do the opposite of Barlow lenses?

There "Focal reducers" that shorten the focal length refractors. This is the opposite of Barlow. You can buy, but are specifically designed for particular fields, and expensive, probably more than your cost of disposal. They come in 0.33, 0.50, 0.63 and power. Creating your own is possible. If you receive two long-term vision of the Objective Lens (a pair of 7x35 binoculars front lens) rather close together, almost touching the curved side curved side, which would be a good idea. Can not use this in a mirror telescope as a Newtonian because there is insufficient space between the diagonal and small mirror to an eyepiece focus. There is nothing you can do with the primary mirror to change the way it focuses light.
