[93, OCA]

This image of open cluster M93 was obtained by Wayne Johnson of the Orange County Astronomers (OCA), with the 22-inch Kuhn Telescope and OCA CCD camera. M93's distance is estimated at 3,600 light-years; its diameter at about 20-25 ly. Its location in Puppis means that it lies in an outer arm of the Milky Way galaxy.

    [M93, Steve Bell]

    This image of open cluster M93 has been obtained by Steve Bell in December 1999 from a SW suburb of Denver, CO. It was taken under considerably poor conditions (poor seeing, severe light polution). It was taken with a 16-inch f/4.7 Newtonian telescope, exposed 75 minutes on hypered TP2415 film (developed in HC-110 for 6 mins). Steve used a RG 630 red filter, mounted after a Lumicon coma corrector/field flattener. This cluster was at a low altitude when shot (~25 deg), in very poor seeing, resulting in somewhat bloated star images.
