I spent a few hours Tuesday night working on a moon mosaic. I got about 10 images in and my small color planetary camera kept disconnecting or stopped working. All I know is I kept getting a capture failed message from firecapture. I went and got my ASI 1600 mm cooled and made a region of interest 1200x1200. That actually sped up The capturing process. I didn't have to take as many videos. mosaic from Tuesday night. 88 1200x1200 500 frame SERs through my Celestron 11" Edge HD with my ASI1600MM-C. Stacked in AS3 and wavelet processing in Registax6. This time I used Microsoft's Image Composite Editor (ICE) to stitch all the images together. It was 90 time faster than Photoshops Photomerge. Final image is 6600X6600 pixels
