Jupiter's Great Red Spot 23/04/05 - Eric Walker

Jupiter taken from Conon Bridge on 23 April 2005 2215h to 2230h BST (2115h to 2130h UT). Multiple images were taken afocally using a 9mm Plossl eyepiece on an 8" SCT using a Nikon Coolpix 5700 digital camera. Exposures were 0.125sec and 0.25sec at ISO 800, f/3.9. The 137 separate images were stacked using Registax3 and processed using Adobe Photoshop CS. The famous Great Red Spot, a great storm that has been raging for centuries, is clearly visible. The apparent movement of the Red Spot due to the rapid rotation of the planet can be viewed on my website at http://members.aol.com/astrophotos/jupiterimages.html www.astrophotos.plus.com
