The Milky Way up Close and Personal: The Stars Like Dust
This is a region of the Milky Way near the star Caph in Cassiopeia. It is a zoomed-in image taken using the 200mm Canon lenses and the Trius M26C OSC CCDs. We are used to seeing the zoomed-out images of … Continue reading

Collimating the Hyperstar 4
In my opinion the Hyperstar 4 is a most amazing piece of kit, and it is beyond me why anyone entering astrophotography for the first time wouldn’t consider this as their route to entry. But there is a caveat. To … Continue reading

Out until 3:00 a.m. last night – the joy of astrophotography.
Well last night was an extremely rare, beautiful clear and Moonless night. I had 2 main things to get on with, one get the array in the North Dome polar aligned and all the cameras/scopes set up ready for imaging, … Continue reading

We are living the Fermi Paradox!
With regard to increasing global temperatures, I believe the planet is now in a state of positive feedback. Increasing temperatures, apart from melting the permafrost, also release huge quantities of Methane, a worse greenhouse gas than CO2. Increasing temperatures also … Continue reading

The Coma galaxy cluster, Fritz Zwicky, and Dark Matter.
This is an original Hyperstar (no collimation or camera angle adjusters) and SX H9C OSC CCD image of the Coma cluster of galaxies. This galaxy cluster was made famous by Fritz Zwicky who studied the cluster, and by applying the … Continue reading

Polar Alignment using Sharpcap
Unexpectedly clear last night, albeit with a nearly full Moon. Still, that doesn’t matter too much when you’re setting up/tuning a system. So it was the Hyperstar 4 on the C11 with the ASI2600MC-Pro camera last night. Started off by … Continue reading

A 10-year Journey on Speed or Why the Hyperstar Really is a High-Speed Imaging System.
No not amphetamines speed, but f# speed, a poorly understood but absolutely critical optical system parameter. It has been a very difficult decision for me to make on how to tell this story. I have had clues about what’s been … Continue reading
