M20 - Trifid Nebula
One of my better nebulae images from Linden Observatory 04/05/2008. Distance estimated at 5200 light years. Red emission nebula and blue reflection nebula shows a wonderful contrast. The star colours are also amazing, a myriad beautiful yellow and blue stars reveal themselves in this image. 9x30 seconds combined images. Celestron GPS11 with f1.8 Hyperstar lens, Meade DSI III camera.
