Double Stars Galore!

  • Richard Harshaw
Part of the PatrickMoore’s Practical Astronomy Series book series (PATRICKMOORE)


Here is a technique thatwill help you split difficult double stars and see greater detail in planets. A difficult double star can be one in which there is a great difference between the brightness of the main star (primary) and its companion, or where two bright stars are very close together. The glare of a bright primary can often drown a feeble companion. Also, when two stars are very close together, the image of the fainter star may actually lie on one of the diffraction rings of the primary.
