Trying to see how far I could push my old SX40 HS bridge camera. This image of M42 was obtained stacking 25 images, 16 seconds exposure each, at 800 ISO. CHDK firmware used to enable RAW format, ISO > 100 on long exposures and intervalometer script. Stacking, background subtraction, maximum entropy deconvolution done with MaxIM DL and final tuning with Photoshop. Despite of the high light pollution some nice details are visible.
