Scope question

Hi,

I’m considering getting into some photography now that I have a Canon 500D and an EQ6 Pro mount. I really don’t think my 10” GSO Newt is mounted strongly enough for photography, so I’m wondering how to approach this.
- Buy stronger mounting (eg ADM) and modify the newt tube (not thrilled about cutting the tube)
- Buy some other dedicated scope

People/books tend to speak of prime focus as the preferred option, so my question is this – won’t going prime focus lock me into only one FOV for photography? Doesn’t this mean I can only shoot some things and not others? Do people have different scopes for different objects? Is there an F-ratio that is considered a reasonable balance – ie reasonable lunar shot and some DSOs?

Options I have considered:
- ED80 – only wide field
- ED100 – narrower FOV
- SCT with focal reducer – 2 FOV options

Interested in people’s thoughts,
Bruce
