Orion Atlas EQ Astro-Tech 106 Refractor Canon Rebel 450D (unmodified)
Image of the Helix Nebula is 17 x 5 min exposures at ISO 400 with Canon 450D, AT106 on the Atlas. Manually guided with a AT65 piggybacked on the 106. Images stacked and calibrated (15 dark frames, 15 flat frames) with Maxim DL, processed with Photoshop CS5, Noise Ninja and GradientXTerminator. Image captured at Tamalco Boat Ramp on Carlyle Lake, in southern IL about 50 miles east of St. Louis, MO. Excellent dark site for the River Bend Astronomy Club. Thank you for your kind consideration.
