  3. Orion's Sword can be seen faintly with the naked eye, usually. However, if you can't see it, it can be found by going halfway down Orion's stage-left leg in declination ("height"), with about the same right ascension ("width") as the middle star of his belt. The Great Nebula just to the north of the sword stars, and can be easily spotted as a nebulosity in the finder-scope.

  7. Alberio is the head of the swan, though it can be somewhat difficult to find with the naked eye on bright nights. To find it, look at the Summer Triangle. Deneb-Vega-Altair forms approximately a right angle and Altair is the furthest south. Just halfway between Altair and Vega, and about halfway up to the center of the triangle, is a medium-brightness star in the finder scope. Looking up close with the eyepiece should reveal it to be a fantastic double star.

  9. Eta Cassiopeia

  11. Look at the stars forming the main "W" of Cassiopeia. Starting at the easternmost star and ending at the westernmost star, the stars are Epsilon (Segin), Delta (Ruchbah), Gamma (Tsih/Navi), Alpha (Schedar), and Beta (Caph). Eta Cassiopiea (Achird) is about 1/3rd of the way from Alpha to Gamma. (from the 4th star to the 3rd star). It is a white to yellowish star in the finder-scope, dimmer than Alpha but brighter than most of the other surrounding stars, and in the eyepiece its dim red companion is clearly visible.

  15. The Double Cluster can be found by going a little more than halfway between Mirfak, the brightest star in Perseus, and Ruchbah (Delta Cassiopiea, the 2nd star in the "W" going east to west). In the finder it will appear as a faint fuzzy spot, while through the eyepiece its beauty is practically unparalleled among star clusters. I recommend using a 40mm eyepiece for this one to get both clusters in the field of view at the same time.

  19. (Untested Star Hop)
  20. Starting at Vega, slew northwest to Eltanin (Gamma Draconis, the brightest star in Draco). From there turn 90 degrees to go southwest about the same distance you went from Vega, and you should find a faint fuzzy spot in the finder, which will be M92. Handily, going about that far again and slightly to the west will bring you to M13, the GREAT globular cluster in Hercules.
