First target of the year is the Crab Nebula. This nebula was formed as a result of a super nova with pulsar winds. It's about 6,500 light years from Earth and is bright enough to be seen with binoculars.

I was able to get about 5 nights of data. i would have aimed for more but diminishing returns kicked in and I can't make much more progress. Here are my details:
