FOR SALE: 12.5 inch f/6 Dobsonian telescope
Homebuilt by experienced telescope maker in 1980. The telescope tube construction is described in a previous SGN issue here: Building 12-inch Dob Truss tube design with professionally-made full thickness Coulter mirror -one of their best, recently re-aluminized. Focuser and secondary mirror/spider is a Novak unit. Standard dobsonian alt-azimuth mount (3/4-inch ply) is a nice wood grain finish with coating of Varathane. This is a large telescope and probably would be happy in a relatively permanent location, but is portable if you have lots of trunk space. Handling the tube is possible for one person but loading into and out of a car trunk is easier with two people. Telescope can be seen at the Fox Observatory later this winter.

Asking $900 but willing to negotiate. Contact John H. at 519-371-0670 or stargazerjohn@rogers.com.

From the Author:
Age Range: 16 and up, Grade Level: 10 and up. The author deals with the three most exciting areas of Classical Physics: Mechanics, Electrodynamics and Thermodynamics -- with a "Glimpse of the Future" chapter describing Einstein's Special Relativity Theory. Using both amusing anecdotes and serious, focused descriptions of major concepts, experiments, discoveries and theories, the author examines the lives and significance of the principal scientists. Non-mathematical explanations of basic concepts and fundamental laws are provided and consequences and applications pointed out. For advanced readers, the Appendix (called Math-Lovers' Paradise) points the way for further study, using advanced high-school mathematics.

Zoe Kestler

From Amazon.com:
Like many women with attention deficit/hyperactivity disorder (ADHD), journalist and popular blogger Zoë Kessler was diagnosed late in life—well into adulthood, in fact. But instead of seeing this label as a burden to bear, Kessler decided to use it to gain a better understanding of herself, and to connect with others through her writing.
In this unique and engaging memoir, Kessler shares her own stories of living with ADHD in a way that is relatable, but never predictable. Inside, she describes how her impulsive behavior has affected her love life; how being disorganized once stood in the way of landing a job; and how inattentiveness has caused certain challenges in her relationships. Kessler also offers key coping skills based on her experience; skills that you can use to focus your energy, become more organized, and boost your self-esteem while tapping into creativity and humor.
Kessler’s story illustrates how being diagnosed with ADHD late into adulthood can be bewildering, but it also shows what a great opportunity it can be to take stock of your life and make real, lasting changes. Whether you share her diagnosis of ADHD, or just like a good story,
ADHD According to Zoë will inspire you and encourage you to embrace your quirks.
