# Telescope Making and Related Resources at ATM (Springfield Telescope Makers)
The Springfield Telescope Makers (STM), also known as American Telephone & Manufacturing Company’s (AT&T)’s amateur astronomy club, offers comprehensive information on various aspects of telescope making through their website [www.Stellafane.org](http://www.Stellafane.org). This article highlights some key sections and resources available for those interested in building or improving their understanding of telescopes and related equipment.
## Telescope Making Resources at ATM
### Build a Dobsonian Telescope
This section provides detailed instructions on constructing both the Newtonian optical tube and a Dobsonian mount suitable for 4 to 12-inch telescopes. It covers every step involved in creating these essential components of your telescope system.
### [Mirror Making](../mc/index.html)
The Mirror Class section offers valuable insights into various aspects of mirror making, including selecting materials, grinding techniques, polishing methods, and more. Additionally, it includes a list of recommended books and internet resources related to this topic.
### [Optical Design](../../optics/index.html)
This area delves deeper into the principles behind optical design for telescopes by discussing topics such as focal length calculations, lens formulae, mirror curvatures, aberrations correction techniques, etc., providing a solid theoretical foundation to complement practical skills gained elsewhere in ATM’s resources.
### [Telescope Mount Making](../../tm/mounts/index.html)
This section focuses on constructing mount systems for telescopes that ensure stability and accuracy during observations. It includes plans for various types of mounts like equatorial, altazimuth, etc., along with detailed instructions on their assembly process using readily available materials.
### [Telescope Optics](../../optics/index.html)
This section explores the science behind telescopic optics in depth by discussing topics such as light propagation through lenses and mirrors, optical aberrations, lens formulae, mirror curvatures, etc., providing a strong theoretical foundation to complement practical skills gained elsewhere in ATM’s resources.
## Additional Resources at ATM
### [Books & Periodicals](../../resources/books.html)
This section lists publications used by STM members as sources of information or reference material while developing or checking the content on their website pages. It serves as a valuable resource for those seeking further reading recommendations related to telescope making and astronomy in general.
### Internet Resources on ATM’s [Links Page](../../misc/links/index.html)
The Links Page contains hundreds of curated links connecting readers with various aspects of telescope making available online across different websites worldwide—a valuable resource for anyone looking to expand their knowledge beyond what is offered at STM itself.
### Mirror Making Courses & Workshops ([../mc/other.html](../../mc/other.html))
This section provides a comprehensive list of mirror-making courses and workshops held around the world, organized by location or event name—an excellent resource for those interested in attending hands-on sessions conducted by experienced professionals who can guide them through every step involved in creating high-quality telescope mirrors themselves.
In conclusion, ATM’s website offers a wealth of information on various aspects related to telescope making and astronomy enthusiasts alike will find it an indispensable resource for their projects or personal learning journey into this fascinating hobby/science field.
