Last night I imaged three comets in Gemini:
C/2007 N3 Lunin mag 9.1
144P Kushida, mag 11.5
C/2006 OF2 Broughton mag 12.2
Epsilon 160 f/3.3, SXV-H9 camera binned 2x2.
Conditions were terrible – full moon and VLM ~ 2.0 in the imaging sector due to sky glow. But I’ve not been able to image for many months, so I needed practice.
OF2 was right on top of a bright star, so its image was not successful. In retrospect, I’d have been better off going for T2 Cardinal in nearby Auriga at magnitude 9.8. I was pushing saturation with meager 90 second exposures with so much background light.
