I'm a BIG Vixen fan and I must say I am shocked more steps aren't taken to control dust and debris. Particularly during assembly. No gloves, no mask, no hair cover. Even the initial pour of the lens glass is done in a pretty dirty environment. I'll bet they get hair, dust and even finger prints on the lenses and inside the telescopes. Given they have such a great reputation I suspect Vixen spends a lot of time on quality checks. I wonder what their rework and scrap expenses are......
There is a similar video for the Takahashi factory on here in which the production is very similar. It is a bit surprising from a modern clean room environment perspective, something you might expect for a scientific instrument, but I quite like this. It's more artisanal.
Very interesting to see the process. I can't believe it's an APO with only a single glass element? Or maybe they didn't show a step where they assembled two or three elements together to make a doublet or triplet APO.
what a genius process to create a Refractor telescope...hahaha..and we say just put a big glass and a small glass on one and another end of a tube and its a telescope
