Much to my surprise, I was able to capture Neptune (magnitude 7.8) and Phi Aquarii (magnitude 4.2) afocally with my hand-held iPhone while observing them through the 17” f/15 classical Cassegrain at the Naylor Observatory. Neptune is passing very close to the class M1.5 III star tonight and will eventually come within a mere 13 arc seconds of it.
At 116x, the pair somewhat resembled the colorful binary star Albireo. I've included a screen capture from Stellarium (with north up) showing the two very different objects and a field star. Triton, Neptune's brightest satellite, is also shown to the immediate right of the planet. I was not able to see Triton (magnitude 13.5), however, even at 432x.
