Farewell Cassini. You have been wonderful!
On Friday, just ahead of Cassini finally burning up in the atmosphere of Saturn as the probe ended its 13 years orbiting the planet, its rings and its moons, the mission’s Twitter feed sent this.

And so, I did.
The picture above was taken in Zakynthos where I was on holiday. I only had my RX100 III “point and shoot” with me, which only has a 70mm zoom lens. That means that I had no chance of seeing the rings of Saturn. So instead I took a photo of the night sky, looking southwest, and relying on mobile apps to point me in the right direction to see Saturn. There was also a little light pollution from streetlights in the village I was staying in.
You can see Saturn in the lower quarter of the picture, just to the right of the Milky Way, which was nicely visible. The photo was taken in the relatively early evening after the sun had set since Saturn was only visible for a few hours before dipping below the horizon.
The picture below makes it clear exactly where in the image Saturn is.
The rings of Saturn are very viewable for the amateur. I still remember the excitement when I was younger, and my mum borrowed a large telescope from the school she taught in that was going unused. We had it at home for a few months, and seeing the rings of Saturn from my suburban back garden, with all the attendant light pollution, was just the most wonderful thing.
Sadly, I don’t have a telescope today – it’s on the wish list – and I certainly didn’t take one on holiday with me.
But looking up and seeing Saturn was a wonderful thing.
BTW NASA has published a wonderful free eBook containing many of the best images of Saturn and its moons, taken by Cassini over the years. It’s definitely worth a download! All the images within have links to the full size images from NASA’s website, so you can download them and make your own prints if you choose.
Up early this morning to head to Brancaster beach along the North Norfolk coast and capture these images. The beach is vast as you can see and to the east of it, there’s a channel, Norton Creek, which separates the mainland from Scolt Head Island. The channel itself leads into Brancaster Staithe where many boats are moored.
The island is quite enticing to get to, but despite being just about reachable at low tide, it can be dangerous and there are plenty of stories of people being trapped or worse.
On the tip of the island is the wreck of the SS Vina, a ship that dates from 1894 and was used as target practice during the war. Today, despite efforts to salvage it, its position means that it’s hard to reach, and it’s visible at low tides.
A few weeks ago, it was the annual RideLondon. This year I didn’t get a space in the main RideLondon 100, but I still popped down to watch the RideLondon Classique race around a central London course. Unfortunately it was a miserable day, with fairly unrelenting rain.
I meant to arrive a little earlier than I did, but by the time I got to the bottom of Piccadilly where the teams were warming up and had parked up their various buses and vans, they were mostly all heading to the start line.
I positioned myself near the top of Whitehall where the cyclist came past twice a lap, once heading out onto The Strand, and once again when they returned around Trafalgar Square, through Admiralty Arch and into The Mall.
The rain meant that nobody wanted to let a breakaway go, and the race was tight all the way through. That also meant that any riders who dropped off the back would stay dropped for the remainder of the race. You felt very sorry when you saw the same riders, lap after lap, doing their own wet-weather time-trials.
RideLondon pays equally for both men’s race and the women’s race, and as a consequence offers more prize money than any other race in the Women’s World Tour calendar. For that reason alone, the teams take it seriously, even though I suspect many would rather race something more akin to the men’s route out in the Surrey Hills and back.
I suspect that the organisers don’t think that they could fit it another ride along that route when they already run both the RideLondon 100 and RideLondon 46 along those roads, making sure that they’re clear for the professional men who set off some 5-6 hours after them. There’s also the issue of TV coverage of both men and women. As things stand the Women get live TV on Saturday evening, while the men get coverage on Sunday afternoon.
Back to the race, and Sunweb took it very seriously. They always had riders at the front of the race, and were looking for intermediate sprint results too. At one stage I found myself standing next to team director or helper who had a radio, and was busily instructing his riders from his viewpoint where I was near the top of both Whitehall and The Mall.
In due course the race was won by Coryn Rivera in a closely fought sprint finish. Cevelo’s Lotta Lepistö came second while Canyon-SRAM’s Lisa Brennauer was third. Just behind them was Marianne Vos who had been reasonably anonymous in the race. I’d not seen her since I’d seen a couple of spectators grab a selfie near the start (I kicked myself I didn’t do the same).
A shame about the weather which I think neutralised the race too much. While a criterium like this affords plenty of views to see the riders, there’s a limited amount they can do to get a break.
Plenty more photos over on my Flickr page.
Long time readers will know that I’ve been playing with a DJI Phantom 3 Advanced for over two years now. I’ve posted a number of videos and photos from that drone in the past and I’ve been very happy with it. However there’s no denying that its size limits where you can take it. You do have to actively choose to take it with you – perhaps at the expense of other things. I’ve had the whole kit fit into a rucksack, but I need other baggage if I’m taking anything else with me. It’s especially limiting for something like a cycle ride.
So when DJI release the Mavic Pro last year I was very tempted. It has more sensors than my Phantom 3 Advanced. Notably my early mistake of crashing the Phantom into a tree wouldn’t be possible with this. And the functionality is greatly improved too with lots more modes making use of the available sensors.
Now I confess that I was actually pretty happy with the 2.7k camera of the Phantom. While 4k video is nice and future proofs myself, I don’t actually have any way to see it back at that resolution. My laptop isn’t that high a resolution and nor is my TV. In any case, there are limits to the bitrate it records 4k at, and I suspect I’ll be using 2.7k to a larger extent with the Mavic.
One other consideration was the ultraportable DJI Spark which has just been released. This only shoots 1080 but is tiny and is a true go-anywhere drone. The arms don’t fold smartly like the Mavic, but it’s very pocketable and is the sort of thing you can easily keep in the bottom of your bag. I suppose my biggest concern was its performance in windy conditions. The UK doesn’t always have perfect drone flying weather, and while I’ll always avoid the rain, bigger beasts tend to be a bit more solid in the air. That said, in some of the YouTube reviews posted, it looks like it performs decently.
Another consideration is the likelihood that DJI will release an updated Mavic at some point soon. The Mavic Pro was released in October last year but it was post-Christmas before it was more widely available. No doubt there will be a new model available ahead of Christmas this year, but it’s like waiting for the next phone or the next computer. There’s never quite the right time to buy.
I still went with the Mavic, and I bought the Fly More pack – as much as anything for the additional two batteries. Other accessories were moderately useful, including some extra props, a car charger and so on, and although the bag is nice it’s not perhaps quite as tough as would be useful for protection. The hub charger is good, although I was slightly disappointed to learn that it charged batteries sequentially. So if you load 3 or 4 batteries onto it, it still only does them one at a time.
You will need to allow time to charge everything up, and importantly, get the most up to date firmware. DJI basically forces users to use the current firmware by making you use an account. If you don’t have the current firmware, your flight distances are highly restrictive. That all said, while it’s still slow, it’s a bit more obvious than the old Phantom 3 way of doing things. I updated using my phone (on WiFi at home), and that gives you a good idea of where you’ve got in the installation and update. Much better than listening for strange sounds from you Phantom!
The little remote is very nice, and DJI include microUSB, Lightning and USB C cables in the box to connect with your phone. I’ve been used to using a Nexus 7 for my phantom – which is basically that device’s single use. And I notice that there are lots of devices around that let you “mount” a tablet to your remote if you want. In use my phone (an HTC 10) worked well, although you’re going to be flattening your phone’s battery using it rather than a bespoke device. I can live with that for the benefits in portability. I’ll probably pack a small Anker battery charger in my DJI bag to recharge my phone if it flattens after a decent flight. I did however notice that the Mavic’s remote loses charge faster than my old Phantom 3 Advanced remote, which could effectively run for weeks on a single charge.
I played a little with some of the modes that track you as move, although I need to learn more about them.
The Mavic has a range of up to 7 km, but UK regulations say that you need to be able to see your drone at all times. There’s no way you can see something as small as a Mavic that far away. And I’m not sure whether a first-person headset would actually be legal here. One of the problems I had with a white Phantom was losing it against a white cloud sky. The dark grey of Mavic makes it easier to spot (and remain legal), and in any case, I probably don’t want to have to trek 7 km to retrieve an errant drone should it decide to land there. (I confess that I’ve never had a drone “fly away” from me. The closest I’ve got is have to use my eyes to fly a drone back when video connectivity caused me problems one time.)
One issue I will think about is bringing some kind of mat or cloth with me take off and land from. The lowness of the Mavic means even quite short grass could get caught by the propellers. I often find myself launching from grass, so a simple and lightweight solution would be useful.
I’m still learning about what the best recording settings are. I use RAW+JPG for photos, but video is another questions. I’ve also never bought any ND filters for a drone, although they do seem to be used a lot by the pros. We’ll have to see.
I did try doing some live streaming. I first tried YouTube, but the app kept crashing repeatedly when I tried it. So I fell back to Facebook which is never anyone’s favourite platform. They limit the video quality a bit for starters. But I confess that it just about worked (I’d embed the video, but Facebook makes that truly fiddly). A few people watched, although playing back, the video quality was at times poor. More annoyingly, there were cutouts continually. I was on 4G so it shouldn’t have been too bad, but it wasn’t great. Still it was good that the phone’s mic could be used for a sort of commentary of what I was shooting.
Otherwise, I’m really happy with my purchase. Expect more drone footage soon. In the meantime, here’s a sample of what I shot today.
Note that I shot on the default settings and have only done a tiny bit of colour correction on a couple of shots. I’m also interested to see what the difference is like between YouTube and Vimeo, so I’ve uploaded it to both, using Premiere Pro CC 2017’s settings.
Following Saturday’s Nocturne, I headed back into town to watch the final stage of The Ovo Energy Women’s Tour, which was concluding on a circuit not dissimilar to previous years’ Tour of Britain finishes. (This year, the men are finishing in Cardiff instead).
Taking in lots of iconic London streets including Regent Street, Piccadilly Circus, Trafalgar Square and The Strand, there were plenty of vantage points. At roughly ten minutes between laps, you had time to walk the course a bit, and in some places see the racers twice a lap.
While the racing was great, the overall winner was never in doubt after Katarzyna Niewiadoma won the opening stage by nearly two minutes. This year’s race was longer and harder than previous editions, but there were plenty of other things to keep an eye. Not least of which was which of the Barnes sisters, Hannah or Alice, would take the overall best British rider (For the record, it was the older sister, Hannah. But Alice showed support from the top of a van with some friends at the final podium as can be seen below).
The weather was good, and the racing fast. A fine way to spend a Sunday.
This weekend saw the return of the Rapha Nocturne, with Rapha resuming sponsorship. These days, the event has moved from Smithfield Market to an area around St Pauls near the Guildhall. While I have no problem with the route, it’s a shame that it no longer covers an area with bars and pubs like Smithfields did. Most places in the City are closed at weekends, and I would suggest that Tesco Express was probably the biggest winner.
Still the racing and fast and frenetic, and it comes into its own as the sun sets later in the evening. I only arrived in time to see the end of the fixie race and the final two races of the evening.
I took photos…
