Coder, software architect, interest in computer science in general. Did research on computer graphics, ray tracing, radio wave and antenna simulation. Like to learn new programming languages. Currently doing Python and Emacs Lisp for fun. C++ for profit. Would like to learn more Clojure.

comment Is the light we see from stars extremely old?
4000 lightyears would mostly be still in our galaxy, which is roughly 100.000 lightyears across, and 3000-6000 lightyears thick. Most galaxies are at least millions of lightyears away.

I edited the question a bit, and would also be able to provide at least one answer.

comment Jupiter FM - What are practical and inexpensive ways for the amateur detection of signals from Jupiter, especially of the transit of her moons?
I would never have guessed that it might be possible with such an easy setup. Very good answer!

What do you mean by tracking? Do you want to plot the orbits of planets? Do you want to track them in real life, using your PC and s motorized telescope? Please clarify.

comment Should I focus more on Aperture or Focal Length for a telescope?
+1 on the Moon tip. I once accidentally pointed my scope at part of the moon and had a shadowy streak on my vision for some days. Good neutrally grey polarization filters that can be tuned from 50%-95% absorption can be had for around 50 EUR (for 1.25" eyepieces).

comment Amateur observing targets for binary star systems?
The link you provided may disappear in the future. Short of pasting everything into your answer, maybe you can select a few candidates from you list that match the users question?

comment Amateur observing targets for binary star systems?
Agreed. It would be nicer to have this question be "What resources are there on easily observable binary star systems?".
