Alan that is amazing shot.  What filter or system are you using that allows you to see the prominence and texture on the surface of the sun?

Hi all,

Great to have a three day weekend after many weeks of work and no play. Here is a picture of our neighborhood star captured earlier this afternoon:

The Scorpion camera used with the 450mm native focal length of my A-P Stowaway frames the full solar disk nicely. Proc! ess in Astro IIDC and Adobe Photoshop CS3.
