M101 the pinwheel hubble

Goal Why M101? Capture a detailed image of a galaxy with hydrogen alpha highlights Why M101? It seemed like the galaxy most likely to yield detailed images & Bright h-alpha regions hubble

Gathering Data the telescope: the exposures: 20” Planewave Cassegrain CDK f/6.8 the exposures: Red: 10x 3 minutes Green: Blue: Hydrogen Alpha: Luminance: Total: 2.5 hours

Before & After Dark Subtract

Luminance H-Alpha Red Green Blue

Color & Hydrogen Alpha
