Cat's Paw Nebula
I have been re-imaging objects with longer exposures and more frequent re-focusing during a sequence as the focal length of refractors changes significantly with temperature. (Improvements don't show up well at low resolution.) This is one of my new images. TOA-130F refractor on EM-200 mount. Exposures: L 6 x 10 min unbinned, RGB each 4 x 10 min binned 2 x 2.
