Comet C/2014 Q2 arrival has been a good opportunity to try photography without telescope, through a regular DSLR camera.
These are some of my tests. I’ve used a Canon 70D camera, with a 18-135 lens, working mostly at F3.5, ISO ranging from 800 to as high as 1600, RAW, tripod, delayed shooting through cable, and 15s (or sometimes 20s) exposures.
Of course I also imaged it with mu telescope and beloved QSI583. Here is the result:
Comet Lovejoy appears as a fuzzy green ball. The intense green is due to the ionization of diatomic C.
