Old versus new — The Unistellar Odyssey smart telescope made me question what stargazing means The age-old pursuit of looking at the heavens is finally getting an upgrade.

It’s been 300 years since Galileo and Isaac Newton started fiddling around with lenses and parabolic mirrors to get a better look at the heavens. But if you look at many of the best amateur telescopes today, you’d be forgiven for thinking they haven’t progressed much since.

Further ReadingThe $3,000 eVscope makes stargazing easy and funThough components have certainly improved, the basic combination of mirrors and lenses is more or less the same. Even the most advanced “smart” mounts that hold them rely on technology that hasn’t progressed in 30 years.

Compared to the radical reinvention that even the humble telephone has received, it’s sad that telescope tech has largely been left behind. But that is finally changing. Companies like Unistellar and Vaonis are pioneering a new generation of scopes that throw classic astronomy norms and concepts out the window in favor of a seamless setup and remarkable image quality.

But is it really stargazing if you’re looking down at your smartphone instead of up at the stars? That’s what I endeavored to find out with the help of two generations of “smart” telescopes, one old and one new, brought together during the recent solar eclipse. Old versus new

In the “old” corner is my GSO six-inch, a Newtonian reflector with a few upgrades. It’s a basic scope, on the high-end of entry-level by amateur astronomer standards, but a solid base for learning. Besides, the real money is in the mount and eyepieces. For eyepieces, I tested using a Baader Hyperion Zoom Mark IV and a Hyperion 5 mm. Advertisement

The bulk of the cost of this setup, though, is in the mount, a Sky-Watcher HEQ5 Pro. This is among the more advanced of the classic style of “smart” telescopes, an equatorial mount that, once correctly aligned (more on that in a moment), can find celestial objects and track them across the sky using a device called a SynScan 6.

The SynScan and the Sky-Watcher use a technology broadly called “GoTo,” a general term for a mount that can find celestial objects in the sky. These scopes first appeared in the late 1980s, and they’ve seen little progress since.

To find those celestial objects, you’ll generally need to know their Messier (M) or New General Catalogue (NGC) numbers, and you put them into a handheld controller that offers all the finesse of a Speak & Spell. (SynScan does make a smartphone app, but it replicates the same user experience, earning it two-star ratings on both the Apple App Store and Google Play Store.)

The total cost for a setup like this? About $2,500.

That’s a significant investment, but it’s mighty affordable compared to the $3,999 Unistellar Odyssey Pro. For that, you get a disconcertingly small telescope, a positively rudimentary-looking tripod mount, and not much else.

But if cost is an object (as it most certainly is for me), you will probably want to buy the $2,499 Unistellar Odyssey instead. Ditching the Pro designation saves you $1,500 and only costs you one feature: an eyepiece on the side, which you probably don’t want anyway.

How do you use a telescope with no eyepiece? That’s where this all starts to get complicated. Page: 1 2 3 Next → reader comments 125 Advertisement Channel Ars Technica ← Previous story Next story → Related Stories Today on Ars

VE Day: Veterans to join King for tea party as Keir Starmer praises ‘selfless dedication’

VE Day: Veterans to join King for tea party as Keir Starmer praises 'selfless dedication'

Veterans are set to join the King for a VE Day tea party today as the prime minister has paid tribute to the “selfless dedication” of the war generation.

Among them will be a 99-year-old who took part in the D-Day landings and a 100-year-old woman who worked in the Special Operations Executive, known as Churchill’s Secret Army.

Director general of the Royal British Legion, Mark Atkinson, said the charity was “proud” to be taking a place “at the heart of these national celebrations and commemorations” on the 80th anniversary of the end of the Second World War.

He said it would be “one of our last opportunities as a nation to pay tribute to those veterans still with us today”.

Evacuees from World War Two and veterans who were still in active conflict after VE Day are among the other guests set to attend the tea party, which will take place in the presence of the King and other members of the Royal Family.

At 12pm, the Royal Family will observe a military procession, followed by a flypast.

It will be the first major VE Day anniversary without any of the royals who stood on the balcony of Buckingham Palace on the day victory in Europe was declared, after the death of the late Queen Elizabeth II in 2022.

More on Ve Day

‘Not just for Britain’

The celebrations come as Prime Minister Sir Keir Starmer praised veterans for their “selfless dedication” and thanked them for a “debt that can never fully be repaid” in an open letter ahead of VE Day.

He said the stories which will be heard this week from those who fought in the Second World War would be a reminder that the victory “was not just for Britain” but was also “a victory for good against the assembled forces of hatred, tyranny and evil”.

Sir Keir said the WW2 veterans “represent the best of who we are” and that without their service “the freedom, peace and joy that these celebrations embody, would not be possible”.

Personnel from NATO allies the US, France and Germany will be among those taking part in the procession in London.

The commemorations will begin with the words of Sir Winston Churchill‘s 1945 victory speech, spoken by actor Timothy Spall.

Thousands of people are expected to line the streets of the capital to witness the celebrations.

Logano gets 1st win this season in OT at Texas

Logano gets 1st win this season in OT at Texas

FORT WORTH, Texas — Reigning NASCAR Cup champion Joey Logano overcame a lot to get his first victory this season.

It came a week after Team Penske teammate Austin Cindric‘s win at Talladega, where Logano had a fifth-place finish that became 39th after a postrace inspection found an issue with the spoiler on his No. 22 Ford. There was also Logano’s expletive-laden rant on the radio toward his teammate in the middle of that race that the two smoothed out during the week. Oh, and he started 27th at Texas after a bad qualifying effort on the 1½-mile track.

But Logano surged ahead on the restart in overtime Sunday to win in the 11th race this year. He led only seven of the 271 laps, four more than scheduled.

“After what happened last week, to be able to rebound and come right back, it’s a total ’22’ way of doing things. So proud of the team,” Logano said.

On the final restart after the 12th caution, Logano was on the inside of his other teammate, Ryan Blaney. But Logano pulled away on the backstretch and stayed easily in front for the final 1½ laps, while Ross Chastain then passed Blaney to finish second ahead of him.

“Just slowly, methodically,” Logano said of his progression to the front. “Just kept grinding, a couple here and a couple there and eventually get a win here.”

Logano got his 37th career victory, getting the lead for the first time on Lap 264. He went low to complete a pass of Michael McDowell.

“I mean, there’s always a story next week, right?” Logano said. “So I told my wife last week before we left, I said, ‘Watch me go win this one.’ It’s just how we do stuff.”

On a caution with 47 laps left, McDowell took only two tires and moved up 15 spots to second. He ended up leading 19 laps, but got loose a few laps after getting passed by Logano and crashed to bring out the caution that sent the race to overtime. He finished 26th.

“We were giving it everything we had there to try to keep track position,” McDowell said. “Joey got a run there, and I tried to block it. I went as far as I think you could probably go. When Blaney slid in front of me, it just took the air off of it and I just lost the back of it. I still had the fight in me, but I probably should have conceded at that point.”

Odds and Ends

William Byron, Kyle Larson, Denny Hamlin and Chase Elliott remained the top four in season points. … Elliott left Texas last spring with his first victory after 42 races and 18 months without one. He hasn’t won since, and now has another long winless drought — this one 38 races and nearly 13 months after finishing 16th. … A crew member for Christopher Bell crawled in through the passenger side of the No. 20 Joe Gibbs Racing Toyota and was fully in the car to reconnect an air hose to the driver’s helmet during a caution in the second stage. It took two stops during that caution, and twice climbing into the car, to resolve the issue.

Fiery end to Hamlin streak

Hamlin had finished on the lead lap in 21 consecutive races, but a fiery finish on Lap 75 ended that streak that had matched the eighth longest in NASCAR history. He was the first car out of the race.

After the No. 11 Joe Gibbs Racing Toyota lost power, something blew up when Hamlin recycled the engine. Flames were coming from under the car and it was engulfed in smoke when it rolled to a stop on the inside of the track, and Hamlin climbed out unharmed.

Youngest pole sitter

Carson Hocevar, the 22-year-old driver who is McDowell’s teammate with Spire Motorsports, was the youngest pole sitter in Texas. He led only the first 22 laps of the race, losing it while pitting during the first caution. He finished 24th after a late accident.

Stage cautions

Both in-race stages finished under caution. Cindric won Stage 1 after Hamlin’s issues, and Kyle Larson took the second after a yellow flag came out because of debris on the track after the right rear tire on Chris Buescher‘s car came apart.

Larson got his 68th overall stage win and his sixth at Texas, with both marks being records. He has won a stage in each of the past five Cup races at Texas, starting in his 2021 win there.

Trump calls for reopening of Alcatraz to house ‘most ruthless and violent offenders’

Trump calls for reopening of Alcatraz to house 'most ruthless and violent offenders'

US President Donald Trump has called for the reopening of notorious prison Alcatraz.

In a post on his social media site Truth Social, Mr Trump said America had been “plagued by vicious, violent, and repeat criminal offenders”.

He added that when the United States was “a more serious nation” it “did not hesitate to lock up the most dangerous criminals”.

“That is why, today, I am directing the Bureau of Prisons, together with the Department of Justice, FBI, and Homeland Security, to reopen a substantially enlarged and rebuilt Alcatraz, to house America’s most ruthless and violent offenders,” he wrote.

Mr Trump said the reopening of the San Francisco prison would “serve as a symbol of law, order, and justice”.

The US president’s latest policy announcement comes after he fired national security adviser Mike Waltz last week in the first major change to his administration.

Alcatraz was infamously inescapable and in the 29 years it was open, 36 men attempted 14 separate escapes, according to the FBI.

More on Donald Trump

Nearly all of them were caught or did not survive the attempt at escaping.

The prison housed some of America’s most notorious criminals, including Al Capone and George Kelly.

It has also been the subject of a number of films, including The Rock, starring Sean Connery and Nicolas Cage.

Alcatraz Island, which is surrounded by strong ocean currents and cold Pacific waters, is now a major tourist site, operated by the National Park Service.

The prison’s closure in 1963 was attributed to crumbling infrastructure and high repair costs.

A spokesperson for the Bureau of Prisons said it would “comply with all presidential orders”.

The Bureau of Prisons currently has 16 high-security prisons, including its maximum-security facility in Florence, Colorado, and a facility in Terre Haute, Indiana, which is home to the federal death chamber.

The United States’ federal law enforcement agency has been the subject of increased scrutiny in recent years after Jeffrey Epstein‘s suicide at a federal jail in New York City in 2019.
