Another view of comet 13P/ Olbers using my close-up setup while the widefield cooked away nearby. Noted this night, showed the plasma tail off-centered from the nucleus, with jetting emanating quite low (very obvious in each of the 60sec subs). I've kept the same field orientation night to night. Framing of the comet was easier this night with the "lowering" of the plasma tail allowing for efficient use of the camera sensor. Olbers is leaving the constellation of Lynx and moving into the UMa starfield. Moonlight is slowly entering the scene with one to two more nights of imaging this comet.
