Summary

[edit]
Description Here is a total 1 hour integration of the Keyhole Nebula in the heart of the Great Carina Nebula tonight in one-shot natural colour. This is at 2350mm focal length / F10. This target has been great to see this season and will be about in the early evening for a little while longer in the Southern Hemisphere. I collimated the scope and re-tuned the polar alignment for 2 hours to get a good image but still got a fair amount of star bloat which caused some ringing. Still, it’s a dramatic and dynamic image of a wonderful fixture of the southern sky. Celestron 9.25″ Edge HD / QHY12 OSC CCD 20 x 180s
