Strange Quarks

I like to call this wide field (12 x 8 degrees) image, taken with a Canon 1100D (ISO 100, f2.0 100mm), nova interruptus. 🙂

The red arrow points to ASASSN-17gk (shown in inset), an 11th magnitude nova in Centaurus I observed on May 21. It also shows the trail left by a passenger airliner as it moved from top left to lower right during the one minute exposure, with tree-tops at bottom.

The signal to noise ratio wasn’t high enough to get a good value and error for the nova’s magnitude via DSLR photometry, so I didn’t submit an observation. The light curve at left shows observations made by others and the polynomial fit below highlights the rough shape of the light curve.
