The Earth and the Universe


Welcome to my web site!  I hope you find something of interest here. 

 The main purpose of  this site is to showcase daylight landscape and animal 

photos and night-time astroimages . There are many daylight photos from Churchill, Canada (polar bear country), California, Utah,

Arizona, Baja, Africa, and Alaska. The astroimages include nebulas, galaxies, star clusters, comets, and planets.


Within a gallery, click on any thumbnail photo or its title to view the larger image. 

If you're a beginning amateur astronomer and thinking about trying astrophotography, 

you might want to read the article in the Articles-tutorials section.
