Profile Manager including Reducer/Extender Values

I have a telescope with 80mm diameter and 600mm focal length, I can enter these values ​​in the bottom two fields. If I now have a 0.85x reducer then it would only be 510mm. If another field were created “Reducer/Extender”, then you could have values ​​of e.g. Enter 0.5x to 5.0x and the "/px should then be converted straight away! Maybe this input field can still be included in the alpha/beta version!?

Aperature Value (meters) should be in 0.00 not only 0.0, unless the image field is still calculated precisely in 0.00 if i type in 0.08 (m)

Thank you and greetings
Daniel
