New AR 2759 in CaK, H alpha ( Double stack and single stack) and White light.

The bright proms made good targets....need to improve the processing skill's to combine prom images....

Excellent shots again Ken. Going to try to have a quick look before work this morning if it has cleared the roof tops in time!

Wonderful stuff!

Hoping against the odds for a gap in the clouds

[David Smith]

Awesome. Weather is poor here, looks like I won't get a look-in until the weekend at the earliest

[Pete Presland]

Excellent set of images, good to see another cycle 25 spot

[Rusted]

Excellent images Ken. Your vast experience shows in their sheer quality.

Do you deliberately correct the solar disk orientation for [more populous] Northern Hemisphere viewers? 

[Merlin66]

Thanks!

I try to orientate the full disk and detail to give north to the top, so we can apply the solar grid to show/ determine the solar latitude of spots and other detail.

Thanks Ken.

That raises some more questions:

How does one lay that grid over the sun's image?

By adding a layer during image processing?

Where does the grid come from? A solar website?

Thanks again.

The solar grid comes from TiltingSun3.

https://www.atoptics.co.uk/tiltsun.htm

It provides a graphic overlay https://www.atoptics.co.uk/tiltgrid.htm

This can be cut and pasted onto your solar image....

Excellent! Thanks again Ken.
