A number of people had trouble viewing the animation I sent out showing changes in the Crab Nebula over 9 years. Heres another version saved as MP4 format. hopefully this will work better. I have a friend working on this video also and im sure his final version will be very nice. Ill send that out when its ready. Note the high proper motion stars in the lower left of the image as they jump back and forth.
One image was obtained in 2016 and the other just a few weeks ago. Two different telescopes (Meade 12" LX-200 for 2016 image and a 10" R-C for 2025 image) and two different cameras ( ATIK 314E CCD for 2016 and QHY 294M Pro for 2025 image). Not the best way to do it but 9 years is a long time! I have? thousands of MSRO images archived going back to 2015 as we save all the data. It might be interesting to create other animations using the old images- who knows what might show up!
