Alfred and I discovered space art, thanks to Gary Briney, NSN digital art moderator, and have taken it seriously. We have been using a PS plugin called “Cosmic pack 2, from UK based Digital Heaven. A moderate learning curve and lots of fun and relaxation. Tutorials are available on their website and they come included in the download.
You can get it here (ask for the hard copy instead of downloading if your connection is not a fast one):

Here are some examples, by both, Alfred and me. Enjoy!

Unbelievable Fabs. Fantastic creations. Last image with earth and moon is my favorite.
All we need to do is put Cpt. Rutherfurd Shackelford in space again.
Hey… I thought I was the space cadet since i work at Kennedy Space Center! Your work is definitely other worldly! You guys are amazing. Just into everything! 🙂

Holy excrement….this is incredible.
Absolutely beautiful work.
Fantastic works Forns Duo — there’s a new Cosmic Pack version which was released a few weeks ago, as you may know already. Cheers!
