Loyangalani Eclipse. An annotated slideshow documenting my visit to Loyangalani, Kenya for the 1973 Solar eclipse. (6 minutes 37 seconds)
Although reduced from the film's original size it can be viewed full screen and still give reasonable image quality.

Imaging the Moon with a Video Camera and Small Telescope. A film based on a six panel mosaic imaged on 9th December 2016. Although reduced from the original size down to 710 x 400 pixels it can be viewed full screen and still give reasonable image quality. (22 minutes 27 seconds)

The Size of Things – The Eta Carinae Nebula. Based on an image of the Eta Carinae Nebula this video considers how creating astro images are but the start of the process into gaining a better insight into the nature of the objects being imaged – in particular by determining the true size of the whole object and any interesting parts. Again, although reduced from the original size down to 710 x 400 pixels it can be viewed full screen and still give reasonable image quality. (11 minutes)

Video Astronomy - An Evening in July. This video demonstrates how the "video" camera and its associated software ToupSky was used to view a number of deep sky objects in late July 2017. The evening's main purpose was to gain a reasonably satisfactory on-screen view of each object. A record of that viewing experience was kept by taking snapshots and the video ends with a comparison of those snapshots before and after later post-processing with Photoshop. (27 minutes)

How BIG is a Light Year? Based on a small computer program that I wrote, this video attempts to convey the true meaning of a light year by considering how long it would take to travel that far using various modes of transport that range from what is presently technologically available, through what is theoretically possible, up to what is offered only by science fiction. It then examines how long it would take to travel to a selected range of astronomical objects using those modes of transport. (24 minutes)

How Big is It? Based on a talk that I gave to the Western Sydney Amateur Astronomy Group in September 2019 this video starts by canvasing the importance of recognizing the size of the astronomical objects that we view in our telescopes. It continues by showing how we can determine that size even if it is not quoted in our reference materials. It concludes by giving some examples of how knowing an object's size allows us to better understand its nature and how it fits into the larger scheme of things. (49 minutes)

Video Astronomy - An Evening in April. This is a sequel to the earlier video "An Evening in July" . It takes you on one evening's real-time tour using a small telescope and a video camera. It covers twelve deep sky objects that are conveniently placed in the Southern hemisphere's mid-Autumn skies. The tour is prefaced by a short description of the equipment being used. Due to time constraints, there was not much time during the viewing session to dwell on each target object after its image had been acquired but a later more leisurely review of all of the objects visited is given at the end of the video. (53 minutes)

Viewing the Southern Pinwheel Galaxy M83. A short instructional video showing how to use the software SharpCap to view the Southern Pinwheel, a barred spiral galaxy located on the border between the constellations of Hydra and Centaurus (12 minutes).
