Is the Vespera Pro 2 better than the Vespera III?

They share the same body, 50 mm quadruplet, 245 mm focal length and battery; the difference is the sensor. The Pro 2's square 12.5 MP IMX676 gives 50 MP mosaics and 225 GB of storage against the Vespera III's 8.3 MP IMX585, 24 MP and 115 GB. It scores 63 on my board to the Vespera III's 60.

What sensor does the Vespera Pro 2 use?

A square Sony IMX676 of 3536 x 3536 two-micron pixels, 12.5 megapixels. My plate solves of five stacks put its scale at 1.68 arcseconds per pixel, which is 245 mm of focal length, exactly as Vaonis states.

How big are its mosaics?

Vaonis states up to 50 megapixels and 4.18 x 2.45 degrees. My Crescent Nebula mosaic came out at 6,207 x 8,054 pixels, 50 megapixels, covering 3.8 x 2.9 degrees.

Does it need a filter for light-polluted skies?

None is built in. Every capture on this page was taken through the optional Vaonis CLS light-pollution filter, which vaonis.com currently bundles with the telescope (First Light Optics sells it separately at £219); Vaonis also sells a dual band filter at $399 and a solar filter at $149.

How many frames does it keep?

Its own logs show 1,502 of 2,701 frames stacked across my five sessions, 56%: 365 of 564 on M 16, 273 of 316 on M 27, 198 of 395 on NGC 7000, 361 of 669 on the M 16 and M 17 mosaic and 305 of 757 on the Crescent Nebula. Nearly every reject was flagged for star shape.

Does the battery last all night?

Vaonis rates it at 11 hours, the longest of the smart telescopes I have tested. That still falls short of a long winter night, so keep a power bank to hand.

What does the Vespera Pro 2 cost?

£2,599 at First Light Optics, $2,990 at Agena Astro and €2,990 from Vaonis directly, with all three showing it in stock.

What have I not tested on the Vespera Pro 2?

I have not imaged planets or galaxies with the Pro 2, tested it under a truly dark sky, timed a full battery run or tried the dual band filter on it.

Rank: #5 of 10 smart telescopes
Verdict: Worth a look

Written by Damon Scotting 8 min read

Buy it if

You want the cleanest raw data a smart telescope gives, so your images need the least editing.
You want big mosaics for prints: mosaic mode builds images of up to 50 megapixels.
You want a sleek one-button observatory with an 11-hour battery and 225 GB of storage.

Skip it if

You want the most for your money: the Seestar S50 Pro has the same 50 mm aperture for well under half the price.
You want filters built in: the Pro 2 has none, and the dual band and solar filters are sold separately.
You want a telescope that wastes little of the night: it struggled to start on some targets and threw away many frames.

“The Vespera Pro 2 was definitely top two in terms of images captured through these comparisons; it is just its hefty price tag that is holding it back.”

What is it for

Four things it is for

Two parts to set up

It is literally just a tripod and a smart telescope, so two parts that need assembling. There is also a small pouch inside that contains three tripod spike legs you can swap in to give it a bit more stability. That is all you have to do.

Mosaic mode

Vaonis were one of the first smart telescope makers to introduce mosaic mode, which lets you capture larger and higher-resolution images than any standard scope. I think backyard mosaic images have a lot of potential for turning into your very own night-sky prints.

A one-button observatory

The design of the app and the telescope itself is very sleek, and I have always been impressed by the look of these smart telescopes. It is the very definition of a cool gadget: a one-button, all-in-one observatory that lets you capture pictures of other galaxies and nebulae from your own back garden.

The longest night and the most storage

The Vespera Pro 2 tops the storage list at 225 GB. The Vespera telescopes are the biggest and bulkiest, which also means they have the longest run times of any of the smart telescopes. None of them can last an entire UK winter night, which is why I always plug in a little portable power bank for some extra juice.

0:00 Two new smart telescopes, one night

0:00 Tonight, I'm going to be testing out the two coolest telescopes in the world right now. 0:03 Side by side, beneath the same skies, I'm going to try and find out which one offers the most stars for your buck. 0:08 We're going to take a detailed look at each scope specifications, as well as the quality of the images produced, and whether or not either of these is the perfect smart telescope for you. 0:16 So, tonight's episode promises to be very special.

0:16 Vespera Pro 2 vs Vespera 3: price and launch

0:18 And that's because I'm not reviewing just one new smart telescope. 0:21 I am, as you can see, reviewing two new smart telescopes, both from Vaonis. 0:26 In front of me right now, we have the Vaonis Vespera 3 and the Vaonis Vespera Pro 2. 0:29 As far as I can see from the specifications, these two smart telescopes are more similar than they are different, but there is one crucial element that separates the two of them, and that is their imaging capabilities.

0:34 Where the two are identical

0:40 So, the goal tonight is to put them side by side and start capturing the same object so we can compare the images taken with each of them.

0:42 The one crucial difference: the sensor

0:48 All right, check that out. 0:48 Look at this. 0:50 So, to start with, this is the Vespera Pro 2.

0:52 Unboxing and setup

0:53 So, that's what is in there, by the way. 0:55 It is literally just a tripod and a smart telescope. 0:56 So, two parts that need assembling. 0:59 There is also a small pouch inside there that contains three tripod spike legs that you can replace the current ones on this tripod with just to give it a bit more stability. 1:09 Okay, there we go. 1:09 That's it. 1:10 That's all you have to do. 1:10 We are now ready to go. 1:12 So, yeah, they've stuck with the same 50 mm aperture of this telescope, which actually means it's the exact same size aperture as a Seestar S50 smart telescope. 1:20 So, it's not really breaking the boundaries much in that aspect. 1:24 So, let's get stuck in and take some pictures.

1:24 Testing on the third longest day of the year

1:26 Tonight is the third longest day of the year, which means technically here in the UK, we don't actually have any astro dark, which is where the skies are really dark and there's no lingering twilight. 1:35 So, this means these scopes are being tested under less than adequate conditions. 1:38 And if that's not restricting enough, how about a 70% illuminated moon? 1:42 This promises to be a tough test for any telescope, but I reckon these two are up to the challenge.

1:48 The app, and mosaic mode

1:48 In order to fairly test them side by side, I'm controlling each telescope separately from individual tablets. 1:52 The app is very well-designed and incredibly informative. 1:56 Vaonis were one of the first smart telescope producers to introduce the mosaic mode feature, allowing you to capture larger and higher resolution images than any other standard scopes. 2:05 But the first thing I began to note was how much of a nightmare the Pro 2 was being at trying to image selected deep sky objects.

2:05 The stacking problem, and why it matters

2:10 It really struggled to get going when it came to imaging the Dumbbell Nebula or the Hercules cluster. 2:16 In fact, something very alarming that I noted was only about one in every three images from the Pro 2 were being stacked, meaning it was wasting two thirds of my observation time. 2:26 I tried turning it off and recalibrating a telescope, but it didn't seem to help much. 2:29 The Vespera 3 telescope, however, managed to stack about one in every 1.8 images, which is a lot better, but still not exactly ideal. 2:37 This is a running theme across most smart telescopes. 2:39 They generally stack a little bit more than half of your images. 2:43 The design of the app and the scopes themselves is very sleek, and I've always been very impressed by the look of these smart telescopes.

2:43 Design and build quality

2:48 I feel like they do appeal to a more premium customer since it is the very definition of a cool gadget. 2:53 Perhaps nothing is more fitting of that title than a one-button all-in-one observatory that lets you capture pictures of other galaxies and nebula from your own back garden. 3:03 Okay, so let's take an in-depth look at the images produced by each telescope.

3:03 How I processed every image

3:06 I tried to get shots of each target with each scope. 3:08 And I also tried to play around with the mosaic mode as much as possible because I think backyard mosaic images have a lot of potential for turning into your very own night sky prints. 3:16 I mean, let's face it, they look incredible. 3:18 I've broken each image down into my own individual editing stages so that you can see how much it progresses from the raw stacked image to the final version.

3:19 M27 Dumbbell Nebula, Vespera Pro 2

3:25 Let me know what you think of this new review video style in the comments down below.

7:38 Inside the 50 megapixel mosaic

7:40 So, what do we think?

7:53 Crescent side by side

8:04 Personally, I think the Vaonis smart telescopes are a welcomed addition to telescope market. 8:08 They offer something a little different, but I'm still surprised to see that with the price they are charging for their smart telescopes, they're yet to step up the quality of their image sensors an extra level and completely dominate the market as the most powerful smart telescopes out there.

8:09 The verdict, and the sensor Vaonis should have used

8:23 Seriously, an IMX533 sensor would be a game changer, particularly since if the Seestar S50 had an IMX585 sensor, which many suspect a new addition will, then it goes toe-to-toe with the Vespera Pro 2 at a fraction of the cost.

8:27 The filters, and what they cost

8:35 The filters are also outrageously expensive, particularly the solar filter. 8:40 All of the smart telescopes I've used come with a solar filter included, as well as an inbuilt duo band filter. 8:45 Solar filters are not expensive to produce, so it's a little shocking how much this one cost. 8:51 Nevertheless, I used it and compared it to other smart telescopes, and it did produce the best images, so at least you get some value for your money.

8:53 The Sun and the Moon

8:57 All in all, I like the Vaonis Vespera telescopes. 9:00 There is a lot to enjoy about them. 9:02 I'd certainly give them a decent 70 plus out of 100 rating in terms of stars for your buck.

9:02 Final score, and your thoughts

9:06 But what do you think? 9:08 Let me know your comments on Vaonis and their smart telescopes in the comments down below and whether you have any plans to purchase one of the scopes featured in today's video. 9:14 You can find a direct product link to the telescopes in the description down below. 9:19 Thanks for watching. 9:19 I'm Damon Scotting and this was astronomical.

63/100 Stars for Your Buck

Pros

“The Vespera Pro 2 shot is the one that has remained the most similar after editing, implying that it has the best raw stack of the bunch.”
“The Vespera Pro 2 does produce the best images of this group on the Dumbbell Nebula: its structure is a lot clearer, with finer details.”
Mosaic mode reaches 50 megapixels: my Crescent Nebula mosaic is 6,207 x 8,054 pixels and covers 3.8 x 2.9 degrees.
The longest run time of the smart telescopes I have tested, rated at 11 hours, and the most storage at 225 GB.
“The Vaonis solar filter did produce the best images when I compared it to other smart telescopes, so at least you get some value for your money.”

Cons

“It was a nightmare getting going on some targets, like the Dumbbell Nebula and the Hercules Cluster, and it threw away a lot of its frames; turning it off and recalibrating did not help much.”
“At the price they charge, Vaonis have yet to step up the image sensor: the Pro 2's sensor has more megapixels, but I find the IMX585 better for image quality.”
“The filters are outrageously expensive: $229 for the light pollution filter and $399 for the dual band, when other smart telescopes build a dual band filter in.”
“No solar filter comes in the box, when every other smart telescope I have used includes one; solar filters are not expensive to produce, so the $149 price is a little shocking.”
“It has the exact same 50 mm aperture as a Seestar S50, so it is not really breaking the boundaries in that aspect.”

All in all, I like the Vaonis Vespera telescopes. There is a lot to enjoy about them.

Who the Vespera Pro 2 is for

Complete beginner

Skip

My recommendation is the Seestar S30 Pro: the same set-it-down-and-go experience for about a quarter of the price.

Wants the best images a smart telescope can give

Buy

Its raw stack needed the least editing of the six smart telescopes in my Eagle Nebula round, and its Dumbbell Nebula was the sharpest of its group.

Mosaic and print maker

Buy

Mosaic mode builds frames of up to 50 megapixels, enough to print a wide nebula large.

Choosing between the Pro 2 and the Vespera III

Buy

The body and optics are identical; the extra money buys the square 12.5 MP sensor, 50 MP mosaics and twice the storage, and the Pro 2 scores slightly higher on my board.

Value hunter

Skip

My recommendation is the Seestar S50 Pro: the same 50 mm aperture, with dual band and solar filters included, for well under half the price.

Planet imager

Skip

At 245 mm and 1.68 arcseconds per pixel it is built for nebulae; Jupiter would span only about 25 to 30 pixels.

Is the Vespera Pro 2 better than the Vespera III? They share the same body, 50 mm quadruplet, 245 mm focal length and battery; the difference is the sensor. The Pro 2's square 12.5 MP IMX676 gives 50 MP mosaics and 225 GB of storage against the Vespera III's 8.3 MP IMX585, 24 MP and 115 GB. It scores 63 on my board to the Vespera III's 60. Versus the Vaonis Vespera III ↓
What sensor does the Vespera Pro 2 use? A square Sony IMX676 of 3536 x 3536 two-micron pixels, 12.5 megapixels. My plate solves of five stacks put its scale at 1.68 arcseconds per pixel, which is 245 mm of focal length, exactly as Vaonis states. Tested numbers and the download ↓
How big are its mosaics? Vaonis states up to 50 megapixels and 4.18 x 2.45 degrees. My Crescent Nebula mosaic came out at 6,207 x 8,054 pixels, 50 megapixels, covering 3.8 x 2.9 degrees. What I captured ↓
Does it need a filter for light-polluted skies? None is built in. Every capture on this page was taken through the optional Vaonis CLS light-pollution filter, which vaonis.com currently bundles with the telescope (First Light Optics sells it separately at £219); Vaonis also sells a dual band filter at $399 and a solar filter at $149. What I captured ↓
How many frames does it keep? Its own logs show 1,502 of 2,701 frames stacked across my five sessions, 56%: 365 of 564 on M 16, 273 of 316 on M 27, 198 of 395 on NGC 7000, 361 of 669 on the M 16 and M 17 mosaic and 305 of 757 on the Crescent Nebula. Nearly every reject was flagged for star shape. From the review video ↓
Does the battery last all night? Vaonis rates it at 11 hours, the longest of the smart telescopes I have tested. That still falls short of a long winter night, so keep a power bank to hand. What is it for ↓
What does the Vespera Pro 2 cost? £2,599 at First Light Optics, $2,990 at Agena Astro and €2,990 from Vaonis directly, with all three showing it in stock. The verdict, the readers and the sellers ↓
What have I not tested on the Vespera Pro 2? I have not imaged planets or galaxies with the Pro 2, tested it under a truly dark sky, timed a full battery run or tried the dual band filter on it.
