Startrail from the evening/morning of 18/19 July 2013. Captured with the OM-D. Using the ultra low light capable 12mm f2.0 lens. Star trails are quite tricky in summertime because of the modest ambient light levels associated with long days and short nights so the window of darkness is limited to approx 2300 - 0300hrs. I set the OM-D on a tripod at 2300hrs pointing due south and framed just above the horizon. This would ensure a nice reversal of arc effect (stars arcing above and below the celestial equator). Using the remote cable RM-UC1 set to continuous I set exposure times to 10s and ISO 250. The same shoot with the E5 would have allowed me 15s @ ISO 500 or 640, but with the OM-D (and fast 12mm lens) longer exposure times or higher ISO was overexposing the bright summer night sky. When shooting in continuous mode with the OM-D ensure you switch off the lcd or it remains on all the time , which drain battery. To add a bit of foreground lighting I shot a few bursts of remote flash across the trees just after the camera was shooting. I then waited till the early hours to retrieve camera. It is possible to shoot in fine jpeg mode but the larger the file, the slower each image write/save time (tiny gaps in the trail arc lines). Medium jpeg setting will suffice. After importing the 1400 or so images from camera to MAC I then ran them all through stacking software (StarStax - freeware) which produces the final composite that you see. A lovely example of Earths rotation seen through the night sky/stars. On this shoot after working out how to swith off the lcd ;-) the battery pack was loaded. The camera was still clicking away at 7am too. Also with the summer heatwave there is no problems with dew at moment. Happy OM-D days. Very impressed with the low light results of the camera. Noise tolerance is excellent (way better than E5) - thank you Mr nice new TruePic V1 processing engine (E5 has TruePic V+).
