Planisphere

Last year after BBC Stargazing Live one of the most popular items was the Philips Planisphere, which Jonathan Ross used on the show to find the stars in the sky.

The Planisphere is the perfect tool for any amateur astronomer. It comes with full instructions on its use, so you can have a quick look at it and be out inspecting the night sky in only a few minutes.

The planisphere also explains how to find the major planets (Venus, Mars, Jupiter and Saturn), sunrise and sunset as well as the positions of the constellations, season by season. Luckily, many of these instructions can be found on the back of the Planisphere itself (along with a Key to map symbols) so that you can always flip it over if you get stuck.

The Planisphere itself is sturdy, flexible and laminated so it won’t be affected by wet surfaces – which is useful if you find yourself outside and there’s a change in the weather. This makes it superior to any cardboard version.

Buy the Philip’s Planisphere from Amazon, makes a perfect Astronomy Gift for someone who wants to learn the night sky.

Jupiter November 2011

It’s been a while since I imaged Jupiter, and I have never imaged it since I got my Skywatcher 120mm ED refractor.

This was taken with a mono DMK21 camera and stacked in Registax 6. It was taken using a Televue 2.5x Powermate. I did try a 5x Powermate but the image was too blurry even once stacked and sharpened using wavelets.

It’s a small Jupiter, but perfectly formed!

FocusMax now behaving itself again

After FocusMax not working as it should after I installed ASCOM v6 and the latest FocusMax version, FocusMax v3.4.0 now works perfectly tonight.

All I did was remove ASCOM v6 and put v5 on, then tried lots of different FocusMax versions – still no joy. I then decided it could not be ASCOM, so put v6 back on again. I then re-installed FocusMax v3.4.0 and now its fine tonight, although it did not work the other day. My PC must have a mind of its own or the pixies have been working overtime in the observatory at night.
