Details:

Active region 12712 just hours before it spawned sunspots. The Sun never fails to impress. Even heading towards solar minimum large active regions such as this can develop, creating beautiful displays of magnetised plasma like a giant flower within the chromosphere. Captured on a modified 150mm solar telescope operating at an effective focal ratio of f30 in the red glow of hydrogen alpha.

Hi,

Thanks for your interest.

This was captured on a homebrew 150mm aperture scope wth a double stacked Lunt35 on the back end and a DERF towards the front. The camera was a Basler acA1920-155.

The image was taken from my back yard as an AVI which was then stacked using AS!3 and refined using Imppg deconvolution software. Colour was added using PixInsight.
