Viewing Planets in Daytime.
Yesterday evening I went out with my ETX to take a look with the solar filter at the first set of sunspots in weeks.
After spending a bit of time there I thought I’d get a look at Venus as it would be easier to see anything of interest with the daytime sky behind it. I could see it clearly and I got to try some colour filters, and trying all of my eyepieces and barlows to get a view.
Next up was to locate Mars – the Autostar made short work of that, and I could easily see Mars against the daytime sky, with well over an hour to sunset. There was not much to see except hints of markings of course, given the 6.2″ diameter of Mars at the moment and the 2″ rayleigh resolution limit of this little scope, combined with the short 350mm focal length. Still, it was nice to actually see the planet at all.
Feeling confident, I went off and selected Saturn. Lo and behold, there was Saturn, just barely brighter than the background sky, but still visible. I could see the rings almost edge on, and the shadow of the rings on the planet cloudtops. Still impressive I think, and points me to the possibility of observing some items during the day at least
