CAPTURE VIDEO with this low-cost camera Lots of accessories make the RunCam Night Eagle an easy match for any telescope or camera lens. by Richard P. Wilds Strain relief Camera 12mm to C-mount adapter A n inexpensive new video cam- era has come onto the scene. RunCam Technology Co., in partnership with the International Occultation Timing Association (IOTA), has adapted one of its sensitive “quadcopter FPV” video cameras for use by amateur astronomers. The monochrome RunCam Night Eagle 2 Astro Edition has a sensitivity of 0.00001 lux and supports the 640x480 NTSC and 720x576 PAL formats. Using CMOS technology, its sensor can detect faint stellar targets even through small portable telescopes. IOTA’s input IOTA has assisted RunCam to produce an incredible video camera at an affordable price. Enhancements made specifically to aid in the observation of occultations include internally controlled integrations of two, four, and eight exposures (pro- viding images of stars across the field of view well into the double-digit magnitude range); improved gain controls for faint objects (which now include settings from 1 to 9); and brightness controls for bright objects (which now include settings from 66 A ST R O N O M Y • MAY 2018 5mm C-mount spacers (2) C-mount to 1 1 ⁄ 4 " adapter ( 1 ⁄ 2 " barrel length) Above and right: The individual parts and the assembled view for the RunCam Night Eagle 2 Astro Edition are shown in a configuration typical for refractors with 2-inch or larger apertures, and all Newtonian reflectors.

An added bonus for star party users is that RunCam includes a digital zoom so others can get a close-up view of objects on the video screen. Of course, your field of view through different optical configurations will vary. When using the 0.5 Knight Owl Focal Reducer without the zoom, a 12-inch f/5 Newtonian reflector produces a field 0.5° wide, or equal to the width of the Full Moon. A 4.8-inch f/5 refractor gives a field twice as wide, a full 1°. And wider (even much wider) fields are possible through camera lenses of various focal lengths. Because of the camera’s sensitivity, bright planets can saturate the sensor when using the Knight Owl 0.5 Focal Reducer. However, I am confident that those inter- ested in planetary photography will find little difficulty in replacing the Knight Owl Focal Reducer with a quality Barlow lens to Knight Owl 0.5X Focal Reducer or equivalent Optional 1 1 ⁄ 4 " extender ring
