An illuminated polar finder scope with a Polar Assist star-field reticle for fast, accurate polar alignment on EXOS-2 mounts — drops into the mount's built-in polar finder bore and lights up the alignment pattern so you can polar align in minutes, even in the dark.

The Polar Assist reticle displays the primary stars of Ursa Major as reference dots. You rotate the mount's RA axis until the dots line up with the actual stars, then center Polaris in the reticle — and you're aligned. The red LED illuminator has an adjustable brightness dial so you can set it just bright enough to see the pattern without washing out the background stars. Powered by two LR41 button cells.

Direct fit for BR-EXOS2, FL-EXOS2GT, BR-EXOS2GT, and EXOS2GT with PMC-Eight mounts. Uses M8x0.75mm illuminator thread.


Key Features
  • Polar Assist star-field reticle — align using Ursa Major reference stars
  • Adjustable red LED illumination (2x LR41 batteries)
  • Direct fit in EXOS-2 polar finder bore
  • M8x0.75mm illuminator thread (current EXOS-2 mounts)

Ideal For
  • EXOS-2 astrophotographers — proper polar alignment is the foundation of good tracking
  • Beginners learning polar alignment — the star-field pattern makes the process intuitive

Very short and very good
Format: eTextbook
I read this book or one similar to it my senior year in high school 1970. It absolutely caught my attention as a way to explain why the continents had separated from Gondwanaland. I really liked revisiting the theory in light of the advances made since then

I love VSI on Kindle
Format: eTextbook
The thing is they take a long time to read because of the look up feature. It's like reading a book in the Library of Congress.

Format: Paperback
There are few who are capable of telling the story of plate techtonics including critical details. Peter Molnar is one of those chosen few who can deliver such a story succinctly and precisely.

Very nice, but very short, book on the subject.
Format: Paperback
This is a very nice, but very short, book on the subject. I learned quite a bit and enough to delve into structural geology and related subjects.

Excellent 120 pages book on a complex subject.
Format: Paperback
I thought this was an excellent 120 pages book on a complex subject. It discusses a variety of subjects besides the title of plate tectonics and which are related to it: continental drift, oceanic seafloor spreading, fracture zones, subduction of tectonic plate edges, faulting, the creation of mountains and plateaus, earthquakes, volcanism, oceanic magnetic anomalies, and the locations of concentrated metallic ores. The text is accompanied by almost 40 sketches and diagrams elaborating on the discussions provided in the text. The book also introduces the grand concepts of Earth geology such as the mantle, lithosphere, and asthenosphere. It also provides a short history of the development of the concept of plate tectonics. Finally, the book provides specific detailed descriptions of the formation of major mountain ranges and plateaus such as the Himalayas, the Tibetan Plateau, Tien Shan, the Tarim Basin, the movement of Eastern Asia, the Andes, and the western US mountain ranges. It also gives a short description of the movement of India from the eastern edge of the African Plate to the Eurasian Plate over the past 90+ million years.
