FOR SALE: 12.5 inch f/6 Dobsonian telescope
NEW PRICE! $789 !

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 by Normand Fullam (a $270 upgrade). Focuser and secondary mirror/spider is a Novak unit. Standard dobsonian alt-azimuth mount (3/4-inch ply) has a nice wood grain finish with coating of Varathane. This is a fairly heavy 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 (and at Starfest this year).

Zoe Kestler

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.
