The IK Pegasi image from a couple of days ago showed double diffraction spikes around the bright star. What? A double star? No... I suspected it was a fault due to bad calibration.
Luminance only, 2 seconds subexposures, 12 stacked shots. FITS Liberator, GIMP. North is up; east is left. Again, I aimed at TYC1671008041.
Captures, in reverse chrono order:
No dual diffraction spikes... So the 28 Aug is a bad image. Or it's a stunningly fast binary.
