Image below was taken with a modified Digital Rebel through Orion ED80 Refractor with Televue .80X Reducer. The ED80 was mounted on an Orion Atlas EQ-G mount. The EQMOD ASCOM driver was used to drive the mount directly via an EQDIR interface module.

Equipment used:

Temperature was 27 degrees Fahrenheit. PHD Guiding software was used for autoguiding. The webcam software WcCtrl was used to enable long exposure modes on the Logitech Fusion webcam while autoguiding.

IC 443 - Nebula:

79 two & one-half minute exposures at ISO 1600 were combined in Images Plus using Adaptive Addition. Exposures were taken over a four hour period.

Full Frame Image was cropped on edge and reduced in size for this 1000 X 727 image (The short streak near the bright star in the upper left of image is the asteroid "44 Nysa"):



IC 443 is also known as the "Jellyfish Nebula" because of its shape. The nebula is the result of a supernova explosion and estimates of its age range from 1000 to 30,000 years. Directly above the "Jellyfish" is a small blue reflection nebula.

Here is info about the asteroid in the image from Wikepedia:

"44 Nysa is a quite large and very bright main belt asteroid. It is also the brightest member of the Nysa asteroid family. It is classified as a rare class E asteroid and is probably the largest of this type (though 55 Pandora is only slightly smaller). It was discovered by H. Goldschmidt on May 27, 1857 and named after the mythical land of Nysa in Greek mythology."
