Speckle imaging contrast curves for NLTT 43564 (GAI 1645+6057) obtained with the ’Alopeke Speckle Imaging at Gemini at 562 nm (blue) and 832 nm (red). The curves show the 5σ detection limits (Δm) as a function of angular separation. The inset of 1″ × 1″ shows the reconstructed speckle image at 832 nm. No nearby companions are detected within 1﹩\mathop{.}\limits^{\unicode{x02033}}﹩2 angular separation of the target.
