Galaxies in the Milky Way
In a pathetic attempt at trying to keep imaging with nights that are like a sunrise, here is a globular cluster in the Milky Way – M56 in the constellation Lyra. I really like globulars with a Milky Way background … Continue reading

First light for the modified Hyperstar III – the “Wall” region of NGC7000

An experiment in animation with deep-sky imaging applications
Last night our faithful old cactus once again flowered and I caught the action with the Canon 40D and TC-80N3 timer controller. So what is this doing on a deep-sky imaging web site? I hope to use the same process … Continue reading
An extremely scary upgrade
I have just half-completed a very scary summer project! The Hyperstar III lens assembly is a fantastic technological achievement which turns an ultra-slow f#10 Schmidt-Cassegrain into an ultra-fast f#2 Schmidt-Camera. There is a slight problem though with all that glass … Continue reading
