Star Trails at PARI. This composite was taken Halloween Night, 2007 (Yikes!)
Besides the star trails (Polaris is in the upper R/H corner), I "painted" the Dish with light from a 1,000,000 candle power flash with homemade colored filters during the exposure(s) to make the dish stand out in relief from the silhouetted trees.
Six 6-minute exposures, layered together using "Luminosity" blending modes in Photoshop. Any questions on how to do this, email me.
I visualized and thought about this for a few weeks before I was able to get access to the site. It turned out better than I had hoped!
