I’ve tried to detect a bit of color by de-focusing the stars slightly, but the secondaries are just too darn faint for that to work — more often than not, they just disappear from view. As you can see, these two double stars are very similar in magnitudes and separation. I have been observing these on and off over the last few weeks. The long-legged Gemini Twins are seen here dancing in the sky with outstretched arms. I guess if I averaged my two completely different measurement methods I'd be closer, huh?

So back to the 10mm Tak I went, and then backwards again to the 12mm Brandon. Like you, I find them uncannily similar, but to my eye I find Kappa Gem to be that little bit more difficult.
