Sol - 25 May 2020

[Hughsie]

Nice to return to solar imaging, always nice to come back to the light side.

 

The Sun, 25 May 2020 with prominence.

 

Capture details

An 500 frame video of the chromosphere was taken to reveal the surface detail of the Sun. The exposure settings were then increased to deliberately overexpose the surface and show the prominence and a second 500 frame video was obtained.

 

Both videos were then stacked in Autostakkert 2 and integrated using the best 50 frames to create two separate image files.

 

Processing details

These two files were then processed with histogram, contrast adjustments and sharpening in PixInsight.

The prominence image was then laid on top of the chromosphere and the position adjusted to match the arc of the Sun’s limb. A mask was then used and painted away in Affinity Photo to reveal the chromosphere beneath.

 

Equipment

Image acquired using;

William Optics Z61 refractor.

ZWO ASI174mm camera.

Quark H-alpha filter.

Sharpcap

Skywatcher EQ6r-Pro mount.

Light cloud was drifting in throughout the session and seeing was fair.
