About this image

The first image I like to take when solar imaging is the full disc as it provides a great overview of what the Sun has to offer the observer at that moment in time time. Also, I have taken similar images of the over exposed disc and used this as a separate layer to reveal the prominences ‘behind’ the main image.

Today, I tried something different and created a mask for the circular disc which helped me bring out the proms then crushed the white point of the disc to completely darken it, just leaving me the ring. Can’t wait to try this again when there are some larger prominences on show.

An interesting use of the masking technique to reveal solar activity without having to wait for an eclipse. Our choice this week for PotW.

I have seen this done before and it is an interesting technique for showing just the Proms.

Very well done.
