CGI Lens Experiment - Moonraker Telescope
Would a CGI telescope rendered in Vray work like the real thing given the correct lens profile, physically correct IOR,
focal length and eyepiece arrangement?
Interesting results shown in the animation at the bottom of this page.
Modern lenses are currently designed and simulated using specialized schematic CAD software, but here's a fun experiment to see what happens when we use a popular visualization tool - Vray Next (Brute Force)
Telescope - Moonraker, 102mm aperture, F7 Achromatic(Doublet) Refractor
Eyepiece - 32mm Plössl
Target - The Moon
Rendering Engine - Vray Next (Brute Force)
Eyepiece - 32mm Plössl
Target - The Moon
Rendering Engine - Vray Next (Brute Force)

Cross Section
Moonraker, 102mm aperture, F7 Achromatic(Doublet) Refractor OTA
32mm Plössl Eyepiece
The 'Moon' is a billboard accurately scaled to about 31 arcmin
View of the Moon(billboard) through the CGI telescope and 32mm Plössl eyepiece, transition from dusk to night.
Results
Yes, the CGI telescope does work almost perfectly when viewed through the eyepiece.
Interestingly, it shows the correct inverted image orientation typical of refractor telescopes when
used without a diagonal; achieving results similar to real refractor telescopes.
It also shows the moon correctly sized at about 22X magnification (715mm/32mm focal length)
Thank you!
