The article evaluates the Series 6000 70-mm Astrograph Quadruplet APO Refractor from Meade Instruments Corp.

The article focuses on the lesson of the Paris 40-inch and 49-inch refractors, which is considered a triumph of optics and engineering and it still in service for education and public outreach. However, the Great Paris Telescope made only a few noteworthy observations before its owners went bankrupt, and no astronomers or institution would buy it, and it was sold off as scrap metal.

The article focuses on the means to observe several stars in the sky. Topics mentioned include the need to determine the direction of the Dog Star's little companion, known as the Pup, in Sirius, which serves as one of the white dwarf stars visible to the average backyard scope, the concentration of the stars within the Messier 41 open cluster, and use of a refractor and a narrowband filter to spot the emission nebula NGC 2359.

The article evaluates the Paramount MyT robotic telescope mount from Software Bisque with the NP127fli apo refractor from Tele Vue Optics and ProLine 16803 charge-coupled device (CCD) camera from Finger Lakes Instrumentation (FLI).

The article presents the author's observation of M57 ring nebula as viewed through her 130-mm refractor at 23x that is bracketed by the stars Beta ((3) and Gamma (y) Lyrae. Sketches showing the Lagoon Nebula, the individual lights of Butterfly Cluster, and the Ring Nebula's gauzy, circular interior, are provided. A chart presents the author's summer favorites, including the Omega Nebula, Great Hercules Cluster and Ring Nebula.

The author talks about the celestial treasures that are best in their class and well-placed for observers at mid-northern latitudes in April and May 2015. Topics covered include the viewing of the Messier 81 and 82 galaxies via a refractor armed with a wide-angle eyepiece, the interest shown of Messier 97 planetary nebulae and the appearance of the Owl Nebula with fairly uniform surface brightness. Also mentioned is the reddish orange Y Canum Venaticorum carbon star.
