Description

The needle galaxy is a famous edge-on spiral galaxy. It is a bit small for my 5.5" refractor on a APSH sensor. Good news is the quality of image from TEC140 is darn good. It could hold the clarity and sharpness even with a large crop. In last couple of days, clear sky finally came after two weeks rain, and it really helps near new moon. I was able to complete this subject starting from March. I shot 10 hours ha, but it barely showed up in the final result. I think ha can be ignored.
