Description

This was basically a short test of my guiding rig (Sky Watcher Evoguide 50mm guide scope with ZWO ASI120mm mini guide camera).  I used my full frame full spectgrum Canon EOS 6D DSLR. No filters. 30 subs of 30 seconds each at 945mm focal length.  Unfortunately my new Starizona 0.63x focal reducer/corrector did not improve on prior results with the Celestron 0.63x focal reducer/corrector as I had hoped would happen.  Coma in this image is admittedly blatant.  This is why I prefer to use refractors.
