Aperture Size Field ASCOM


Hi everyone,


I recently was messing around with the ASCOM driver for the EXOS2GTw/PMC8 and I noticed a field for "Aperture Size".

Seeing as there is already a field for "Telescope Aperture" what is "Aperture Size" and how do I find it / calculate it?

I feel like this is probably something very obvious so please bear with me as I've not figured it out.


Thank you,
