2 Moons 2 Scopes 130 years apart

[philj]

Ive been meaning to do this comparion for some time, first chance tonight.

1975 ish Towa 339 80mm F15 compared to 1845 ish James Smith of London 3.25" F18 refractors using Olympus OM D EM 1 mirrorless camera.

 

I reckon the Towa has it but the antique uncoated Smith aint far behind

Towa 80mm F15

Smith 3.25" F18

 

Each scope was mounted in turn on my HEQ5

 

Heres a pic of the Smith on original mount, (Sporting non original dew shield), with Jupiter in the background

Very hard to tell the difference, but IMHO the Towa does look a tiny bit sharper. Still, impressive performance for an antique lens!

Good comparison, and very little between them.
