Hi, Yesterday was one of those occasions... The evening was beautifully clear here. The passes of KH's USA 129 and 186 were too much in twilight (I did see USA 186 visually though, but got no points) and I tried to photograph a pass of IGS 1B half an hour later. The Tamron lens needs to be focussed using the "live view" function of my camera (Canon EOS 450D), as it has no "hard stop" at infinity, like most modern lenses. I ran into trouble though. Pointed it to Arcturus but no star to be seen on the screen whatever I tried. Dito with Vega, Deneb. Frustration! Then worry. Was my camera malfunctioning?!? I looked up. And saw a bright IGS 1B majestically sail accross the sky. Grrr! I took the camera again. And then the quarter finally fel.... Yep: forgotten to take off the lens cover.... * bangs head against desk repeatedly * - Marco PS: made up for it with an astrophotography session, imaging the milky way wide angle with the Tamron. It picked up a lot of stray satellites, proofing that like the EF 50/2.5 Macro this (Tamron Di II 18-50/2.8) is a very nice lens for photographing satellite trails (the EF 50/2.5 Macro goes somewhat deeper and is sharper, but the Tamron is wide angle and its sharpness very decent, better than the EF-S 17-55/3.5-5.6 IS that came with the camera). ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@wanadoo.nl Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com ----- ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
