ST-237 User's Images

Because many of the most beautiful CCD images seen in magazines and on the internet are captured with top of the line cameras, it can leave the impression that one must use the most expensive cameras to obtain high quality images.  The ST-237 is a lower price camera that is nevertheless a high quality instrument capable of both high resolution greyscale and high resolution color imaging, as these sample images from various ST-237 users demonstrates.  All of the images on this page were taken with the ST-237 (see pricing).  The internal color filter wheel (see pricing).  The telescopes used range from relatively inexpensive 8" SCTs up to the AstroWorks Centurion 18" f/2.8.  These images have been reduced in size and resolution for presentation on this web page.
