Great report Sab! Nice descriptions, glad you're getting some sky time. Only serious omission was comet C/2014 Q2 (Lovejoy) - should knock your eyes out with the 12" SDM. ;) :)

Thanks for coming in Robin & Ken, I'm a bit out of my depth!



Because a comet is an extended object, without a slit the spectrum becomes self-contaminating. For the broader cometary spectral...

Comet C/2014 Q2 (Lovejoy)

This comet is currently (and easily!) the brightest comet in our skies at the moment. It is nearing naked-eye brightness and is really well placed for southern observers. I've obtained a few rough...
