About this image

Comments by Graham Roberts state that:

When the object is right, such as the Rosette Nebula, narrowband imaging using the ZWO camera produces exceptional results.  This is evident in these recent images where it’s now possible to clearly see structural elements of the nebula, as well as the star fields located within.  Frankly I am very excited by these new images and can’t wait for next year to come around again!

Research at Leeds University just published suggests that the Rosette Nebula is a disc but I believe my eyes and this image and many others which says otherwise!
