[Nathaniel Fairfield] aka [thandal] was curious about the actual rotation and axis tilt of Venus. He decided to spin up at GitHub Python repository to study the issue further, as …read more Continue reading Amateur Estimates of Venusian Day using Arecibo Data
Back at CES 2023, French smart telescope maker Unistellar launched a new model that could digitally remove light pollution from cities to give users a clear view of the stars. Now the company has improved on the formula with its new Deep Dark Technolog… Continue reading Deep Dark tech clears up light pollution for inner-city stargazers
Named after world-renowned photographer and astronomer David Malin, the Southern Hemisphere’s most prestigious amateur astrophotography competition conducted by the Central West Astronomical Society (CWAS) has delivered a stellar collection of images c… Continue reading Amateurs excel in the 2022 David Malin astrophotography awards
On astronomical telescopes of even middling power, a small “finderscope” is often mounted in parallel to the main optics to assist in getting the larger instrument on target. The low …read more Continue reading StarPointer Keeps Scope On Target with Stellarium
An incredible image of a solar eclipse has won this year’s Astronomy Photographer of the Year competition. Selected from more than 4,500 entries, the stunning shot was awarded alongside other highlights, including a number of technically masterful phot… Continue reading The Astronomy Photo Awards features the greatest shots in the universe
Starting projects is easy. It’s the finishing part that many of us have trouble with. We can hardly imagine completing a project after more than a decade, but seeing the …read more Continue reading A Milky Way Photo Twelve Years in the Making
NASA has released a collection of 50 stunning Hubble images to celebrate the veteran telescope’s 30th anniversary, which took place earlier this year. The images show 30 cosmic objects, ranging from planetary nebulae to galaxies in incredible detail, r… Continue reading Hubble gallery showcases 30 cosmic gems visible to amateur astronomers
While most people who make the trek to the path of totality for the Great American Eclipse next week will fix their gazes skyward as the heavenly spectacle unfolds, we suspect many will attempt to post a duck-face selfie with the eclipsed sun in the background. But at least one man will be feverishly tending to an experiment.
On a lonely hilltop in Wyoming, Dr. Don Bruns will be attempting to replicate a famous experiment. If he succeeds, not only will he have pulled off something that’s only been done twice before, he’ll provide yet more evidence that Einstein was …read more
[GregO29] had a 10″ GoTo telescope but at 70lbs, it wasn’t really portable. And so he did what any self-respecting CNC enthusiast would do, he put his CNC skills to work to make an 8″ Newtonian reflector, semi-Nasmyth mount telescope of his own design. It also gave him a chance to try out his new Chinese 6040 router/engraver with 800W water-cooled spindle.
What’s all that fancy terminology, you say? “Newtonian reflector” simply means that there’s a large concave mirror at one end that reflects a correspondingly large amount of light from the sky to a smaller mirror which then reflects …read more
