About this image

This is a 3x60s stack of frames taken using a Samyang 135mm, f/2 lens and ASI2600MM from Chile this morning. See the timelapse here. Comphot gives a magnitude of 3.5 in a circular aperture but the central part is saturated so I think it will be brighter than this. The FoV is 6.4x5.1 deg and the main dust tail goes out of the frame. There is a fainter dust fan to the right of the main tail and, presumably, the gas tail at right angle to it.
