A nice afternoon's planetary observing...

Recommended Posts

With a couple of our guests I did a bit of Jupiter watching this afternoon. It was a very hot sunny day with a lovely clear blue sky and Jupiter was at a nice high altitude so we watched the transit of Callisto's shadow well clear of the equatorial belts, which were showing that classic brick red colour. A 26 Nagler gave a good high power for a comfortable view.

Go on, ask me!! How did we do it?

Was Jupiter 90 degrees away form the Sun, creating a little bit more dark sky background and was the lunar crescent visible to provide a bearing?

"Manual go-to", i.e. old-fashioned use of setting circles?  And perhaps a polarizing filter, to darken the blue sky background. If not high mag itself makes the sky surrounding the planetary disk dark enough . . .

0.8 metre RC, alt az, direct drive with field derotator. It's a fully professional instrument. Six million Euros. Gulp.

Wow, Marc is an amateur?

Great looking bit of kit, lucky you that you get to use it.

Hope you didn't forget to remove your Nagler. ;)

Something to do with aperture. Marc, my fellow astro-provider, rather better endowed financially than I am, has a moderately large device at his disposal... http://a404.idata.over-blog.com/4/15/06/42/DSCN7169.JPG

Darned impressive!!!

No, he's a professional provider on a far larger scale than I am. The instrument had public funding as well.

Odd, this, but in the flesh (the considerable flesh!!) it's orange.
