Hi Marco, It's a Canon 600D with EF-S 18-55 IS II lens, which I only got just recently. Still getting the hang of night-time shots, as I'm not an expert photographer. I read the messages from yourself and Greg the other day and took photos of my GPS app (on android) at the start and end of my session, also taking into account the 16 leap seconds, and I've previously checked this against the US navy time servers on the net. The Canon time was off during last nights session by 4 seconds, which I corrected for as well. Obviously with this setup, I can't get sub-second accuracy. But for a start, I'm ok with it. A proper low light video camera and video time inserter like Derek and Kevin use is on my list for Christmas :) Mal ----- Original Message ----- From:marco.langbroek@online.nl To:"Mal Ninnes" , "satelliet lijst (SeeSat)" Cc: Sent:Wed, 12 Dec 2012 19:13:49 +0100 Subject:Re: North Korea satellite observed Op 12-12-2012 15:01, Mal Ninnes schreef: > Hi all, > > I've managed to capture what may be the first in-orbit image of the DPRK's first satellite. > > Image was taken at 11:17:23 UTC on Dec 12, from Sydney, Australia. > Area of sky is around: > RA 2hr35m40.9sec > Dec -50 14'39.4" > > 13sec exposure (still determining whether the timestamp is the beginning or end of the exposure). I'm still also trying to determine whether this is the A or B object (it's getting late). > > > http://www.flickr.com/photos/89853686@N02/8267193172/in/set-72157632231123670/ What camera and lens combo was this taken with? Image EXIF times usually refer to the start of the exposure, but of course you first have to have a properly synchronised camera clock. If that is not the case, your times can be way off. Most camera clocks run out of pace very fast (seconds per day). - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands e-mail: sattrackcam@langbroek.org Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 456016 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspotcom Twitter: @Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
