With clouds hanging over the observatory, there is another option. You can process raw images from a remote observatory. Raw images for this project were taken last September from a remote imaging observatory that is located in New Mexico at an elevation of 7400 feet. The telescope was a 106mm Takahashi FSQ 106EDXIII telescope. A total of over 100 half hour narrow band exposures were stacked for a total exposure time of 50 hours. This is actually a two panel mosaic that was stitched together with Microsoft ICE. Other software included Adobe Photoshop, Maxim DL, and Pixinsight.
