Evolution of Solar Prominences,
02-03 April 2016
The montage of images below shows the evolution of prominences on the solar limb during the period 02-03 April 2016. The images were taken with an Altair GPCAM camera and Coronado PST on an NEQ 6 mount. Close ups used a 5x Barlow lens.
In order to show the prominences it is necessary to use an exposure which is too long for the centre of the solar disk, which therefore appears burned out.
Each image is created from a 400 frame video. The best 15% to 20% of frames are stacked into a single image using SharpCap 2.7, then some sharpening is applied to bring out detail.
