To that end, I start with a review of optical interference, after which I provide a systematic approach on how the ATM can build an optical interferometer without any input other than this book and homemade, surplus or common off-the-shelf components. For the Williams interferometer the experienced telescope maker is likely to have accumulated a well-stocked??? See Appendix D or a list of suppliers. This book describes how to make mounting hardware for little more than the time and effort it takes to build them but if purchased new or even used these would be a significant additional expense. Spherical mirrors are relatively easy for the ATM to make and null test to a high level of accuracy.
ATM Letters - Journal for Amateur Telescope makers
Although the internet can be a wonderful resource for first-time telescope makers, it can also be a source of great frustration. Listed below are mini reviews of a selection of telescope-making books from my personal library. My selection is based on a couple of assumptions about who you are. That said, what is in here is very good.
Notes from an Amateur Telescope Maker’s Journal, Part 2
In preparing these pages, in addition to our personal experience, the published references listed in the table below were used. In the rightmost column, we have provided some additional information and commentary about these publications. Hopefully this additional information will help you choose the book or books that meet your needs.
When choosing your first telescope, the most important quality to look out for is the aperture diameter rather than the magnification. You should avoid any telescopes that are small but claim that they have some great magnification power, of x or even x, at all costs. To see faint objects your telescope needs to be able to collect as much light as possible and so the wider the aperture the wider the diameter of the telescope tube , the fainter the object that you can see.
