Image below was taken with a modified Digital
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
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."
