20240510 Aurora

This is an naked eye visible event here in Scotland, and maybe actually from the whole UK.

I planned a wee trip to the Dechmond Law which is the highest point in the small town of Livingston West Lothian.

Such a powerful and amazing show!  Glad to have my family with me.

20240509 Sun (H-alpha)

 AR3664 and AR3668 are probably one of the biggest active regions that I have ever taken, glad to have a few minutes of gaps among the cloud.

I would like to take some white light shots with my 8" SCT but then the cloud forbid me to do so.
