Here you will find a collection of DFM Engineering's latest press releases, white papers, and articles.
DFM Engineering, Inc. has emerged from innovating in stealth mode. We are proud to present our brand new products, including our LEO Scope™ and LEO Comm™ product lines.
It's not an evolution, it's a revolution! Unlike any previous telescope, with the combination of field of view and photographic speed, the LEO Scope™ and LEO Comm™ products will leave your jaw on the floor! It's hard to shock those of us at DFM who have been in the telescope business for decades, but our latest product has done exactly that. Created to address the growing needs of Space Situational Awareness (SSA), DFM Engineering has created an entirely new type of telescope. While it may bear some resemblance to our previous telescopes, the performance is out of this world!
After upgrading the Modular Precision Absolute Control System (MPACS) for US Spaceforce's Ground-based Electro-Optical Deep Space Surveillance System (GEODSS), DFM was tasked with creating the next generation Space Domain Awareness (SDA) telescope that would rival the world's finest and most relied upon systems. DFM Engineering rose to the challenge and built a telescope / camera system with a 26-inch aperture F/1.7, 4.4-degree FOV, optimized for autonomous use that offers world-class Pointing, Acquisition, and Tracking (PAT) - it's even compatible with the GEODSS Sensor Control Group (SCG) software. These products have been designed for scaled deployment and upgradeability (adding laser communications capability).

Informed by many years of practical experience in the industry, Dr. Melsheimer has written multiple scientific papers for the astronomical community, many of which are currently quoted and referenced in today's marketplace and educational institutions.
A very popular, comprehensive paper entitled: How to Buy a Telescope for Your Institution is an excellent guide and safeguard when in the market for a scientific instrumentation expenditure of high regard.
The paper outlines the necessary steps involved in purchasing a research-grade telescope augmenting features such as:
It is an excellent guide and safeguard when in the market for a scientific instrumentation expenditure of high regard.
Another popular paper, presented an AAS meeting, is titled: "A Very Wide Field, Very Fast Telescope" as a study of the U.S. Naval Observatory 1.3M telescope. The design performance, optical fabrication techniques, and optical test results are discussed in detail and the paper is referenced frequently.
In an engineering discussion documentation, The Optimal Telescope, Dr. Melsheimer analyzes telescope structural components such as: Steel vs. Aluminum, Geometry, Deflections, and Pointing. These, also, have been referenced regularly.
Dr. Melsheimer's draws on his extensive technical experience for his paper entitled: Comparing Telescope Drive Technologies. He offers a plethora of performance criteria with comparison charts. In this paper, he investigates the various drive technologies and discusses the advantages, disadvantages, and performance of these telescope drive systems.
Observatory Design and Construction, by Dr. Melsheimer is an excellent guide strategically outlining the necessary criteria in planning and constructing an observatory designed to house a research-grade telescope. Dr. Melsheimer's extensive experience offers a unique perspective with practical applications coupled with modern technological solutions to current observatory design obstacles. He provides handicapped accessible features to meet current standards. He works closely with customers to determine telescope features, building and dome requirements, integrated mirror handling, and control room size and placement.
Dr. Melsheimer addresses the necessity of efficiency in an astronomical telescope by a remote user over the internet in his paper, Internet Telescope Performance Requirements. Consistently high performance from the telescope, instruments, support facilities and control system is required for successful real time direct imaging. Dr. Melsheimer thoroughly outlines these determining performance factors for research study.
Dr. Melsheimer has previously supervised the mechanical engineering department, optical and mechanical shops at Lick Observatory. He has also been a member of many of the design review teams for the Keck Telescope and has designed the Transportable Lunar Ranging Station at the MacDonald Observatory.
