Large prominences – August 28, 2016

Scroll down to content

Two very large prominences have appeared today on the Sun, and of course I had to “be there”.

TS 115mm F/7 APO Refractor, Baader UV/IR cut filter, Quark Chromosphere H-alpha filter, ASI 174MM camera.

And a short animation, showing some prom-dancing of these large prominences:

And a full disc image acquired with the TS 65mm F/6.5 APO, a few hours after the above image. This one was done while preparing together with a friend of mine, Claudiu, for an ISS solar transit. It would have been my first H-alpha ISS transit, but one cloud said “Not this time!”. So, I was left with a 12-image mosaic to process, for quite a long time. The end result is more towards an artistic view, since I’ve processed the image with an “inverse limb illumination”for a more…artistic view.
