Ordered BGO to image LDS 873. This is a faint but fast binary star in Pisces. 70 year period. I hoped the magnitude 11.4 and 12.9 stars would both be visible...
Luminance only, 2 seconds subexposures, 12 stacked shots. FITS Liberator, GIMP. North is up; east is left.
Also gathered RGB data, 6 seconds each, 12 frames each.
Also known as HIP 4927. SkyTools says the primary star is TYC 01195-0960 1 but I had to use 1195009602 with the 'bot.
This is a tight pair. SkyTools says 3.23". That's close to the limit for this system. The software shows the B star to the west, nearly due west. I can't see anything... Did a deep give into all the channels.
Is the seeing a factor? The CSC predicted the seeing at 1/5 or bad. Or am I working below the limits of the rig?
