    I went to upgrade the mount and scope, now using a Maksutov Cassegrain on a Celestron CGEM Mount.

    Here is a picture I took yesteday (with my webcam)! (Jupiter with two moons)

    Actual Supernova visible right now and in the next couple of days (with a small telescope or Binoculars)

    To orient yourself, Stellarium (freeware) is very useful or "Mobile Observatory" or Sky Maps on Android.

    This is great stuff, it has not peaked yet.

    Is it possible to buy filters or detectors allowing one to do astronomy in frequencies transparent to clouds?

    In particular I wonder if I could use some kind of CCD to do ultraviolet astronomy on cloudy days?

    Some basic reading seems to tell me that both IR and UV are not just scattered by cloud cover but emitted (in the case of IR) and reflected(in the case of UV) such that neither is really appropriate for straight forward observation.

    Any thoughts on cloudy night viewing?

    DIY radio telescope is probably your best bet.

    Failheap is great for news about Ukraine.

    Not so good for news about space.

    A 30 meter iron and rock behemoth just went past our head. The best of us saw it 5 days before it wizzed by. The rest of us can only catch the replay and be glad it went well.

    Speaking of things blowing up in space; http://phys.org/news/2014-06-physici...r-thought.html

    The SN 1987A event had an unexpected 4.7h delay between neutrinos and photons. A new theory has been proposed which takes into account vacuum polarization where, during the brief moments the photons splits into a positron and an electron, the effect of gravity changes with the particle change.

    Philae landing candidates. This will be a glorious thing to observe.

    this is quite awesome http://spacecraftforall.com/data

    Snazzy website for the team that took over the defunct ISEE-3 satellite. Has all the latest data from the craft, as well as some cool history of the project and the satellites flight through space.
