OPTICAL 02 October 2020 ------------------------------------------- Site 0435 Pinelands (Cape Town,South Africa) 18.5101 degrees east 33.9368 degrees south altitude 25.5 metres ZWO ASI 174MM cmos camera with telephoto lens set at about 80mm focal length and aperture f/2.8. Field of view 7.74 by 4.86 degrees, 2x binning and image scale 28.8 arcsec/pixel. Timing provided by Dimension 4 and Network Time Synchronization (NTP) and hopefully good to 0.1 seconds ( or better!). Mostly 4.00 second long exposures used and hopefully camera gives 4.00 seconds as time recorded in FITS file header as start of exposure time . In some cases start or end of trail not too well defined so mid trail estimated for position. FITS images reduced in NOVA.ASTROMETRY.NET to provide plate solution and SAO DS9 used to determine coordinates from trails produced during exposures. ASICAP used to produce FITS files. So far appears to be the best program for capturing as best control over how image appears.

Will report later if anything interesting.
