Ray Gralak's CCD Images

Link to Sigma Beta 10

One of my favorite hobbies is Astronomy. Over the last two years I've become more steadily involved with CCD imaging. Most of my images have been taken from my light polluted backyard in San Jose, California (Silicon Valley), but I have taken a number of images from such remote locations as Fremont Peak, Henry Coe State Park, Pacheco State Park, Lake San Antonio, and Mount Lassen (all of these locations are in California).  This page and my dedicated H-Alpha page present the best of the CCD work I have done. 

To take a look at my equipment please take a look at this link: Astronomy Equipment (updated December 22, 2000)

In addition to this page please take a look at my collection of  HAlpha monochrome and color LRGB images. You can find them at this link:

Ray Gralak's Hydrogen Alpha CCD Images

Here are some of the CCD images I have taken with various cameras. I started with a SBIG ST-7, then upgraded to a ST-7E then finally, a Class 1 ST-8E. All three cameras are of the non-anti-blooming variety, although I also owned an anti-blooming ST-7 for a while.

WARNING: Many of these images are large and may take a while to download! I've sometimes included reduced in size versions of images that download faster and fit better on lower resolution screens.
