Electromagnetic theory, vol.2

3rd version, with a foreword by means of Sir Edmund Whittaker. Oliver Heaviside endured lively medical paintings for greater than twenty years after the e-book of the 3rd quantity of his Electromagnetic conception. His unpublished notes, a few of which have been present in 1957, contained many discoveries: the methods in which Heaviside's principles built in the course of these two decades is incorporated in long appendices during this 1971 variation.

The Moon will be extremely detailed. Star clusters, nebulae, and galaxies (invisible to the naked eye) will vary considerably in their glory and appearance. Do not forget to allow your scope to come to ambient temperature ("cool-down")--this is extremely important! Otherwise, excess turbulence within your scope will produce nothing but "blobs" at the eyepiece! Allow at least an hour for cool-down time. Sometimes, the "seeing" (upper atmosphere turbulence) never settles down, and you will be frustrated with the views all night...

Comes in lots of colors, too! com/ offers to gussy up your scope. He sells things like "tube rings" and one-power sights, which most people find useful: Otherwise sight down an edge of your Tube Box; that's how you aim the thing! Care Instructions: Do not store your scope outside. If you don't have a large closet or garage, put a lampshade on your scope and store it in your living room! Remember: Door jambs destroy homemade focusers! Cover your scope when not in use--dust and moisture--are the enemies!

1/4" Distance Between Side Boards =............ 13-3/4" Distance Between Side Boards =......... 15-3/4" NOTE: All of the plywood sizes for the Tube Box and Rocker Box of a Dobsonian telescope are determined by the width of the tube. By using the above formula, you can calculate the sizes of the plywood for any size Dobsonian telescope. htm (2 of 11) [9/6/2001 11:33:35 AM] Making a Dobsonian Mount ASSEMBLING THE ROCKER BOX 1) Glue and nail two PART C pieces together for the Bottom Board, this will be the base of your soon-to-be Rocker Box.
