M8 and M20 Region in Sagittarius

   
M8 (the Lagoon Nebula) and M20 ( the Trifid Nebula) occupy a very rich region in Sagittarius. There are many star-forming areas in this section of the Milky Way. Some less popuar nebulae in the center left part of the image include NGC6559, IC1274, IC1275, and IC4685.  
   
Optics: Nikon 300mm f/2.8 ED lens
Camera: Canon XS (Hutech modified); Raw capture; ISO 800
Mount: Orion Sirius EQ
Guiding: SSAG on 200mm Takumar lens
Exposures:

24 five min. exposures @ f/8
24 five-min. exposures @ f/2.8

Processing:

Camera was focused using Live View. Raw images were converted using Canon's Zoom Browser EX. Converted images were calibrated, aligned and combined with ImagesPlus. The f/8 and f/2.8 sets of images were processed separately. These images were stacked in Photoshop and a layer mask was applied to reveal the finer detail in the f/8 image. The final image was adjusted in Photoshop.

This was taken on 8/8/10 and 8/12/10 at the Nebraska Star Party. Seeing was good. Humidity was high the first night with fog appearing after 2:00 AM (a rarity for this area). Temperature: 70F
