Abstract: Due to advances in high speed CCD cameras, speckle interferometry has now become an area of research for amateur astronomers. This paper describes several approaches to calibrating the pixel scale of a camera and suggests that using a transmission diffraction grating with a monochromatic light source is the best method.

Speckle Interferometry of Close Visual Binaries
Russell M. Genet
- 01 Sep 2015
TL;DR: Speckle observations of close visual binaries have been made by an eclectic group of student, amateur, and professional astronomers with an EMCCD camera on two smaller telescopes and then on both 2.1and 0.8-meter telescopes at Kitt Peak National Observatory as mentioned in this paper.

TL;DR: The first automated speckle interferometry was achieved on the 0.25-meter telescope at the Orion Observatory on the night of September 12, 2014 by Teiche et al. as discussed by the authors, who used a Van Slyke instrument slider to switch between a Canon T3i acquisition camera and an Andor Luca-R EMCCD science camera.

TL;DR: In this article, a simple modification to the video drift method and corresponding Vi dPro analysis program now makes reaching magnitude +16 a reality for modest amateur equipment, which is a quick and efficient way to ob- tain position angle and separation measurements.
