Hi Malcom,
Did the 20" have a name with its previous owner, or one from its maker like a model?
I aske this as one way to name it is as a derivative of its previous name. I called my 17.5" Odessius after its original configuration of "Odyssey II" as the model.
The only other scope I've named is my 8" f/4 dobbie, called F4. Any guess why???
Is there a particular line or curves in the scope you really like? Someone it reminds you of - you mentioned Henrietta. A woman that's had a major influence in your life, like a teacher?
Where I'm coming from is to give you different was to draw inspiration from to find a name. It's your baby...
