    a curriculum for Ten Mile River to try to get the scouts through the astronomy merit badge The operative word here is try because it s not actually possible to do in the time frame allowed by camp but we did work on them getting through the visual observations which is a big deal 10 constellations 4 of which are in the zodiac 8 conspicuous stars 5 of which are first magnitude plus sketches of the Big Dipper over a 2 3 hour period to observe the sky rotation We ll call it a limited success since all of the boys managed that part we practiced every clear night before the 3 hour observing session on Thursday And they all learned to use a planisphere and were required to use it to plan out what things they were going to observe that night I did fire off an email to BSA national about the updated Astronomy merit badge requirements I m not at all happy with the Observe a planet and describe what you saw requirement as it s too vague We did do that one during camp but we used a telescope to observe Saturn so there was a

    its high tangential COR make for fascinating behavior like how you can make a superball bounce back and forth by giving it backspin On each bounce it will reverse spin and keep going for quite a while The paper is fun but they also do a lot of careful measurements on how different types of balls slide when they hit a surface To do that they used a very low

  • Testing Astro Video Capture in Linux
    interest was in whether or not I would be able to do video capture The latest thing I ve been playing with is setting up for occultation timings Have a look at the IOTA web site occultations org I ve purchased all the equipment a GPS video timer a Supercircuits PC164EX low light camera which they just recently stopped selling and already have telescopes So the question was could I do video capture under Linux I ll worry about analyzing video after I have capture working The answer is yes But its more complicated I have multiple USB capture devices not all of which work equally well The first one I had picked up had drivers software that didn t work particularly well under Window 7 64 bit The video screen would blank out when I started capture which was highly annoying After posting on the IOTA Yahoo group I received some recommendation and went out and bought one of each As it turns out the first one I bought I already had I purchased the Diamond VC500 One Touch I actually already had one That was was the one that was working strangely with the Window 7 64 bit software I m not sure why it was working strangely but it was do bad I had already deleted the old software and my camera had been sitting idle When I received the new one I loaded the software and it worked fine I dug the old VC500 out of a box in the garage and found it worked fine too remember we re still talking Windows 7 here So the next test was for Linux It started out not so good At this point I didn t have a normal lens for the camera so I couldn t be

    fine too remember we re still talking Windows 7 here So the next test was for Linux It started out not so good At this point I didn t have a normal lens for the camera so I couldn t be sure but the image didn t look simply out of focus it looked downright scrambled So I bought a C mount lens waited a few days for delivery then tried again As it turns out not all VC500s are created equal I have two now and there is no external visible difference Howeve lsusb shows one tiny difference the bcdDevice number for one is 40 01 for the other it is 40 02 The 40 01 works consistently and without fail Disconnecting and reconnecting causes no problems Stopping video killing vlc while it is connected nothing causes any problems The 40 02 is another story Kill vlc while it is connected and you ll have to disconnect the VC500 and wait a few seconds before reconnecting In fact just about anything including just stopping video from vlc will cause the VC500 to start scrambling the video That s what I had seen before I got the lens So yes video capture works But not all VC500s are created equal Roland Roberts s blog Log in to post comments Printer friendly version PDF version Navigation Calendar Gallery Constellations Messier Objects M27 The Dumbell Nebula Resources Astronomy Books Buying A Star Buying A Telescope Clubs and Organizations General Interest Imaging and Astrophotography Magazines Mailing Lists and News Groups Science Toy Suppliers Software Weather Information Tips and Tricks Roland s Corner Recent content About Copyright Search form Search User login Username Password Request new password Science Daily Mercury Mercury gets a meteoroid shower from Comet Encke Mercury gets a meteoroid shower from Comet Encke More Science Daily Venus The aliens are silent because they re dead The aliens are silent because they re dead More Science Daily Mars Antarctic fungi survive Martian conditions on the International Space Station Antarctic fungi survive Martian conditions on the International Space Station Rotation speed may be bad news for Red Planet pioneers Rotation speed may be bad news for Red Planet pioneers The aliens are silent because they re dead More Science Daily Jupiter New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts NASA telescopes detect Jupiter like storm on small star NASA telescopes detect Jupiter like storm on small star Simulating the jet streams and anticyclones of Jupiter and Saturn More Science Daily Saturn Cassini completes final close Enceladus flyby Cassini completes final close Enceladus flyby How water escapes from Saturn Magnetic reconnection How water escapes from Saturn Magnetic reconnection Explosive energy in Saturn s magnetic bubble More Science Daily Neptune Evidence of a real ninth planet discovered Evidence of a real ninth planet discovered Mars to lose its largest moon Phobos but gain a ring
