As Brian mentioned, exposures may be long, so get the most sensitive camera you can afford, with regulated cooling. There is science that can be done using different wavelengths, like limb-darkening or atmospheric detection, but you would do an entire transit in one wavelength then repeat with another wavelength - not changing during a transit. I have encountered no photometric issues using a filter wheel.

I would start with variables too.
