After putting on my new C6N on the AVX mount, I set out to a Bortle 4 area around Wassaga Beach for some astrophotography, mainly to see the difference from the achromatic refractor I used previously.
This images were also shot with a 60 second exposure to limit tracking errors due to periodic error and a poor polar alignment.
The main difference in these images are the star diffraction spikes clearly visible on brighter stars. These are caused by the four spider vanes supporting the secondary mirror in the reflector telescope. Also, because this scope uses a mirror instead of lenses, there is no chromatic aberration. It is free of it because of light reflecting off the mirror, instead of refracting through the lenses.
