Object info

IC417 & NGC1931 (small object left of center) are also sometimes referred to as "The Spider and the Fly" the resemblance does however not show from this image as it needs a lot more exposure time (preferably Ha) to bring out the fainter details of IC417 ! The object is located in the constellation Auriga and is near IC405 and IC410. Actually the nebula visible at lower right of the image is IC410. Both objects are about 10.000 light-years distant and are embedded in glowing hydrogen gas.


Processing

CCDOPS was used for focussing. Image acquisition was done using CCDSOft.
All separate frames were calibrated, aligned and stacked in ImagesPlus 2.8.
Photoshop CS4 was used for further processing - curves adjustment, levels adjustment, etc. Noal Carboni's Astronomy tools were also used.
