A book review by Dick Luecke British author Richard Holmes won laurels for his biographies of the Romantic poets. In Age of Wonder he extends his talents to Europe’s second great epoch of scientific discovery—a period roughly from the late 1760s through the 1820s. Holmes describes this fruitful era of science through the lives of [...]
From the President Thanks to everyone who attended our April Business Meeting and to those who helped with the voting for our Young Astronomer’s Program. Soon some very deserving aspiring astronomers will be using their very own telescopes and binoculars to participate in the hobby that we all love and enjoy. Each winner will also [...]

My Daughter and I went down to the North Andover soccer fields early this evening to observe PanSTARRS. We did see the comet although we had to deal with some thin bands of passing clouds near the horizon. We also observed the Orion nebula, the double cluster, Jupiter, the Pleiades and the moon. Our tools [...]
I went to IRWS this evening, mainly to try to see the comet, but also to participate in some public outreach because I can rarely make it to our star parties during the week. There was a presentation there last night, but the observing component was bumped to tonight because of cloudy weather. About 7 [...]
by Donald E. Pensack Collimation is the alignment of the optical parts of a telescope. Though lining up the secondary under the focuser is essential for uniform illumination of the field of view, there are only two critical alignments in Newtonian collimation: the Focuser Axis (aligned by adjusting the secondary mirror), and the Primary Axis [...]

By Kandy Rathinasamy I got started with astronomy about a year ago, so I’m a relative newbie. Here are some tips that I hope will help you get started. You don’t need a telescope You don’t need a telescope to get started. There’s a lot to see with the naked eye. Learn about the constellations [...]
by John Boudreau. I was essentially clouded out of the Venus transit back on June 5th, only getting about 5 minutes of visual with a pair of filtered binoculars only minutes before sunset. However in the weeks leading up to that event, I was observing and imaging Venus regularly as it was becoming an ever thinning [...]
As part of a school project on astronomy a local student joined NSAAC and learned the fundamentals of astrophotography, and trained his scope on the moon. We think he will get an A.
The eyepiece takes the image produced by the objective and magnifies it and projects it at infinity into your eye.
This time-lapse image was captured in the parking lot one pleasant summer evening. The stars appear to move around a central point, when it is actually the earth that is moving.
The Veil Nebula in Cygnus is my favorite summertime deep sky object. I first observed it with an 8scope many years ago. It is most likely a supernova remnant of a star that exploded 30 to 40 thousand years ago, although remains of the progenitor have never been identified. The Veil consists of three sections spanning about 2.6 degrees.
