After quite a long time in limbo I recently began to rehabilitate my backyard observatory. It had lain fallow for a couple of years due to life distractions and the rationalization that I could go there any time I wanted. After shoveling out the POD from a recent mid-February snowstorm I went inside to inspect the mount, telescopes, and surroundings.

Having recently dived into astrophotography, I have found that most problems I face have been faced before, and have a plethora of solutions. Typically, those fall into a couple of categories – expensive, and cheap do-it-yourself. But backyard astronomers being the type of people they are, they tend to share one endearing characteristic – heavily over-engineered for the problem at hand.

In the fall of 1609 Galileo began studying the Moon with his spyglass and he would sketch the features he saw. We need to understand that the magnification of his spyglass by this time was around 21x and it had a very narrow field of view such that he could only see about half the width of the Moon. His telescope was also rather long at about a meter (39.4”) so it must have been very difficult for Galileo to track the Moon with his makeshift tripod.

Last month I wrote in Part 1 about Galileo’s discovery that the wandering star, Jupiter, was a planet that had four moons. Recall that my motivation was reading the book Discoveries and Opinions of Galileo published in 1957 by Stillman Drake, a Canadian historian and authority on the complete works on Galileo. This article will cover Galileo’s observations of sunspots which got him into hot water with the Roman Catholic Church in 1616.

This question eventually surfaces on just about every mount found in the low to medium range. If you pay $6,000 for a mount it has probably been tuned during manufacturing. For a mount like the AVX what you get is an assembled piece of machinery that is simply bolted, snapped, or screwed together and never really tested or adjusted for fine operation. That is why your mount is usually stiff or tight. I recently bought a new Advanced VX mount as a part of my down-sizing program.

It is often recommended to modify DSLR's for deep sky photography. It may be one of the first topics a beginner comes across and sometimes the recommendation sounds like modding is an absolute necessity. There are good reasons not to do it, for example the camera is used for daytime photography as well or the budget does not allow either to have an existing camera modified or get a modified one. I don't want to go deeper into it. I'm also not opposed to modified cameras. I just would like to show what can be done with an unmodded relatively low priced DSLR if modding is not an option.

Back in my days as a Quality/Reliability Engineer, we had a motto by which we lived; “Good, cheap, easy……Pick any two”. For this project I chose cheap and easy. I would keep my computer, cameras, and accessories in my den when not in use, and the mount and telescope could stay, semi-permanently situated outside. The search began. Who in the world makes a portable or temporary structure large enough to provide security for a 10” f/4 newtonian riding on a Celestron CGX mount?
