This is the first image from my Orion 120ST with no filters except for Mother Nature. It was hazy and partly cloudy most of the night. I used a SAC7 at F/15 with a 3X Barlow. I stacked 50 images manually and touched up in Photoshop to bring out the cloud belts. The haze kept the brightness down and prevented the usual fringing you get from achromatic refractors.
