telescope for photometry (PMTs)

Hi,

We are planning to set up a ready to go kit, including telescope + photometer + courses & practicals guidelines.

This will be aimed at emergent countries universities who have a physics/maths department and would like to develop astronomy but don't have access to any facilities and have limited budget.

The practicals will be on differential photometry and variable stars.

We will be using SSP photometer from Optec.

If you have any adviice from your experience about what telescope will give the best setup (Reflector/Refractor, cassegrain/newton focus...) ?

We would like to have an optimal setup option as well as a budget one (still allowing valuable scientific observations).

Thanks a lot for any input you can provide me with.

Cordially,

Laure
