Thomas' Thursday Post (Observatory)
Well, the day started off well with the lovely train ride to Utrecht, and lots of pictures of amazing doors umm, but the piece de resistance (correct my horrible french Adam when you read this) of the day in my opinion was the observatory. We again met with Teamen (Is that the correct spelling of his name, I assume not, but I spelled it phonetically.) who it turns out is very much a telescope fanatic. We attempted to see the moon with his replicas of some period telescopes. But to me the most interesting part was discussing with him the process of (at high magnification) of taking pictures of different wavelengths of the same object as at high magnifications the indivitual wavelengths are separatable. The term he used was Astrophotography for that topic. I found it interesting, with Adam, Nathan and Trent. Maybe they remember further what we discussed with Teaman (again correct my spelling if you know the appropriate spelling of his name.)
I also really enjoyed this part of Thursdays trip to Utrecht. I found it very fascinating to be able to use the two free lenses in order to replicated a tubeless telescope and be able to see the moon.
ReplyDeleteThat the flawed lense caused the Reds and blues to separate so much was really fascinating and made me better appreciate the work that goes into making lenses.
ReplyDeleteit was definitely interesting to hear the principles that power modern telescopes described by the application of the ideas that were present within the Galileo telescopes.
ReplyDeleteI thought it was cool hearing about how to get rid of the color separation was with putting a concave and convex lens of different material together.

ReplyDeleteGuess who just put the family telescope up for auction this weekend?
ReplyDeleteSorry, Nathan!
