| Notes/ Conditions |
Conditions- This time of year the conditions are always hot and dusty. The evening taking the Luminance frames and also the Ha data was no exception. Cooler, but similar conditions when taking the RGB channels. Ha blended to luminance then added to RGB data creating a Ha-LRGB. Image has been cropped. |
