"sRGB + gamma" single-shot color processed in CCDOPS ver 5, Photoshop CS2: levels, AstroTools: 2x 'make stars smaller', 'space noise reduction', 'local contrast enhance', color balance (towards blue), unsharp mask.

Comet McNaught, 6:59pm Jan 20, '07 from Bonny Doon Airfield. 1 minute guided. sRGB single shot color processed in CCDOPS5.

The Lagoon Nebula - Oct 14, 2007 from Bonny Doon airfield with the Astro 9 students. 5x5min stack The nebula was low in the southwest, only 15 degrees up, and color separation due to refraction is evident on the brighter stars. Photoshop CS2: levels, saturation, smart sharpen (gaussian). AstroTools: 4x 'make stars smaller', 'deep space noise reduction', 'space noise reduction', re-leveled. Then 'enhance DSO/reduce stars', 'lighten DSO', saturation, cropped, releveled, unsharp mask. Compare this fine photo with one I took using the 80mm f/6 Megrez refractor, under perfect high Sierra conditions. The bigger, faster Meade 8" f/4 here is the easy winner, plus more experience with Photoshop. |
