Wow, nice job Patrick!
But there's something wrong there - to get the real view the sketch needs to be flipped vertically - and then what you have marked "Schickard E" is actually Lehmann, and vice versa. Only know because I spent a fair bit of time looking at it through the eyepiece last night - reflector so rotated view but not flipped. Must be what the refractor & whatever diagonal did to your view.
Cheers -
