A little while back, I uploaded an image of the Pinwheel Galaxy (M101). I uploaded it today, and here is the annotated image:
There are no fewer than NINE other galaxies in this image--pretty amazing!
But the fun does not stop there. As you might have seen in my other post earlier today, you can enhance the image by combining your data with the image, or you can combine your data with that from professional sky surveys. Here's the results of those operations:
|M101 enhanced with other data uploaded to astrometry.net|
|M101 with Galex overlay|
|M101 with SDSS data|
