Stellar Products Image Gallery


Updated July 20, 2013.

Each photo is described in detail, including exposures, equipment used, dates, and processing. All of the 2000-2003 images used a 10" Newtonian telescope with the AO-2 to project the image to the SBIG ST-7 camera and CFW-8 filter wheel. The effective focal length is 14.1 m, giving a plate scale of about 7.6 pixels per arcsecond (3.8 pixels/arcsec in 2x binned mode). This is slightly over F/60, so even the central core of the Airy disk is spread over 4 pixels. Iimages taken in 2004 used a Philips ToUcam, at about F/33 or at F17. The latest images in 2013 used an SBIG ST-i camera.

Previous years images - each new year generally brings better images, so these are not as good as the current ones. They are included to show how better equipment and better techniques lead to better current images.
