Jupiter from Float Bay View
We are just back from a week’s holiday near the Mull of Galloway. It was a good chance to try out our great little new car, a Skoda Fabia. We managed to load up two bikes as well as the telescope kit, so with all of Galloway’s gardens to visit we had plenty to do.
Astronomy wasn’t really the main event, given the lateness of the darkness – but great to get away from Glasgow’s light pollution. I did manage a repeat of Jupiter’s moons are in the frame though, and our holiday cottage had a good veranda where I could set up the tripod – so it wasn’t far off astrophotography the easy way. I made it even easier by making do with a quick ‘movie’ sequence on my Canon EOS 500-D camera via the Maksutov 150 telescope. Back at the ranch in Glasgow I used AutoStakkert!2 to stack 250 frames of the 3 minute movie, and tweaked the result just a bit with GIMP to wavelet sharpen the Galilean moons.
When I packed the telescope kit for Float Bay View I forgot to put in my wee ZWO ASI224 ‘planetary’ camera, see Jupiter revisited (again), and some new technology. So I had another go with it, from the back garden at home. Using the ZWO ASI224, and a x2 Barlow Lens delivers the most magnification I have got. That’s why only the 2 innermost Galilean moons (which I have annotated) are in the field of view. And you can see Jupiter’s Great Red Spot , which is a Gigantic storm raging in Jupiter’s thick atmosphere. The Great Red Spot is three times larger than the Earth and was first seen by the English scientist Robert Hooke in 1664. But with the difficulty of focusing via the laptop screen and not a very good night for ‘seeing’ (as astronomers say) my image is not very sharp 🙁 better luck next time?
