imaged STF 2146 faster (Halifax)

Shot double star HD 156162 aka STF 2146 aka SAO 30299 again! Faster still! Twice as fast as 12 days ago. Also switched to the SBIG camera. In Draco.

Struve 2146 in luminance

Luminance only, 0.1 seconds, 12 subexposures. FITS Liberator, GIMP.

Caught it in stunning conditions...

Well... I don't think AB is round.

This is the shortest value allowed with the BGO rig. So I cannot shoot any quicker. That's it.


WDS entry updated! There's no B. The tight companion is near C. See the 29 Aug '21 blog entry for details of the change.
