Hello Sean,
Yes there are side vents and the backing plate is removable though once viewing I think it is better to close the sides to prevent any reflections or light from iPad screens etc reflecting off internal tube surfaces.
I think the end plan is to also include a pot to vary the fan speed to keep the scope as near to ambient as possible.
It could also turn out to be an unnecessary modification
that's why it's good to practice on Phil's scope
at the moment I am removing the filter screens to test the change in airflow.....
(maybe someone will volunteer their refractor for me to cut into to test active cooling in one.....
)
