This is a combination of 15 images, each of 120 seconds The images were taken with a SBIG ST-10 3 CCD Camera attached to an Televue 85mm F/4.2 telescope (F/7 with 0.63x focal reducer).. Each of the images was corrected with a dark frame and a flat field.
An STV was attached to an OGS 20" F/8.1 telescope for guiding!!!
