Description

As the terrible weather and seeing over the last months allowed for just a few hours of imaging, I collected some data on M51. It was my first time using an H-alpha filter to bring out some of the details and nebulae in the galaxy. Adding the Ha was challenging at first, but after some great advice in the forums on here, I now am pretty happy with the result using Continuum Subtraction on the Ha.
Considering the image only contains about 4h of data, I like it a lot.
