Hello Scarodactyl, Hello Robert,
Thank you for your insights!

I have to sell a considerable amount of objectives and am looking for a reliable and hopefully fast way to check for defects, i.e. fungus, delamination etc. On the web, I saw procedures of shining lasers through the lenses and inspecting them with measurement eyepieces and am curious what people her...

They claim to have a resolution 10 times that of Hubble. That would coincide with your calculations.

I have tried to read the pertinent chapters in the Handbook of Alma

Unluckily, that is not an easy cuisine.

This video introduces the instruments and their combined resolution and gives some information about the star: https://www.eso.org/public/germany/videos/eso1436b/ plus some virtual tours https://www.eso.org/public/products/virtualtours/https://www.eso.org/public/products/virtualtours/ Also the corre...

Hi Rik, that is right. Alma = Atacama Large Millimeter Array

Not exactly macro, but look at the resolution. It used to be that even the best telescopes could image stars just as single points (pixels). Now we can see a protoplanetary system in surprising detail.

Hi houstonx,
I contacted Leschaco. At my location they do only corporate customers. At least, as far as shipping a container is concerned. Whether they might handle my airfreight I will hear tomorrow.
Thank you.

Thanks again, everybody. Enrico, I have friends going to Japan in 2 weeks and will ask them to investigate the germ-killing stuff. Lou, your silica procedure makes a lot of sense. That is the kind of information I was looking for. firesto, I moving household stuff, books and less fragile instruments...

Hi Macro,
dessicants are on order. Thank you for your hints.

Hello Enrico and Ichty, thank you very much for your valuable insights and links. Much obliged. Ichty, I had several rather sobering experiences with the German customs office in the past myself. Once, I had to go to one of the distant offices you mentioned to pick up a flash light that cost 4 US$ o...

I am moving house from Asia to Europe in a couple of months and am considering different ways of shipping heaps of cameras, lenses of all sizes, objectives and other optical equipment. Everything going into the shipping container will stay there for at least 2 months and probably get very hot and hu...

the magnification is 6x, just about what you would expect from the focal lengths of the lenses.
