Sharpless 1 – 89 in Cygnus
by Vern on Sep.10, 2007, under Astronomy, Planetary Nebula
Located in constellation Cygnus at RA 21° 14′ 09″ and Dec +47° 46′ 24″ is a faint (vmag 14.5), oblong-shaped planetary nebula known as the “Moth Nebula”. I only picked up the middle part of the “moth” with the Stellacam which may be seen at the center in the image below. The Stsci Digitized Sky Survey image shows faint “wings” extending to the upper left and to the lower right.
Image above taken from “Cactus Flats North” in the Pawnee National Grasslands near Briggsdale, CO on Saturday morning, Sept. 8, 2007 around 2:33 am MDT. Celestron Nexstar 11 telescope with F3.3 focal reducer and Stellacam II video camera used to capture 30 images. Camera set at full gain (14/14), medium gamma, and 256 frame integration (8 sec). Registax4 used to flat field adjust, dark frame subtract, align, and stack images. Cropped and brightness enhanced with PhotoShop Elements 2.
Sky was clear, 2-3 mph wind, transparency very good, turbulence about 6/10, temperature 51°.F.
