The ED102 102mm f/7 Essential Apochromatic ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multicoated optics. This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. This is a versatile optical tube assembly that is powerful enough to clearly see the planets and bright deep sky objects. It has a relatively small form-factor that makes it perfect as a portable grab-and-go option, or set up on a dual-mount rig for astrophotography/astroimaging.

A mounting cradle-ring clamps over optical tube assembly (OTA). The cradle-ring allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle. Its two-speed rack-and-pinion focuser helps make fine-focusing fast and precise. A 90° star diagonal is also included for more comfortable viewing. The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.

Good quality book.
Format: Paperback
Bought these because I bought one for my grandmother every year for Christmas. It is good quality, but I have only opened it one time. I got it for sentimental reasons.

Outstanding Book
Format: Paperback
Great book, a classic that seems more timely now than ever! First read Dr Akbar’s book years ago and bought this updated edition to replace the copy someone borrowed & never returned (another sign of a good book when they don’t get returned). So glad to have this new copy to revisit the deep wisdom and insights Dr Akbar lays out. He explains the painful & persistent psychological & sociological chains of slavery clearly and irrefutably. This book is a must read for anyone who wants to better understand why it’s so hard to heal the terrible wounds of slavery — even today, even generations past physical shackles....

Quick & Informative Read
Format: Paperback
I only called it a “quick read” because when I get warped in a book, I lose track of time. This is one of those books. Quite an easy read. Recently Purchased the other books that were recommended with this one.
