The Cone Nebula is an immense pillar of gasoline and dirt some seven light-years tall. It’s situated within the constellation Monoceros 2,700 light-years from Earth, and is bathed in ultraviolet radiation from close by stars, which it re-emits as good purple gentle. And proper now, it’s in my front room.
Or reasonably, it’s on my cellphone, in my hand, as I sit in my front room staring in surprise on the majesty of our galaxy. Anybody may take a look at photographs of the Cone Nebula at any time, in fact, however this isn’t only a photograph of the Cone Nebula — it’s a reside feed* of it taken by the sensible telescope quietly doing its factor in my again yard. That sensible telescope is the ZWO Seestar S30 Professional, and it’s really, breathtakingly superior.

Smarter than your common telescope
Good telescopes have been round for just a few years and have been a complete game-changer for beginner astrophotographers resembling myself. That’s partly as a result of they value a fraction of what you’d have to shell out for a devoted astrophotography rig with separate monitoring mount, telescope, digicam, and filters, but additionally as a result of they’re so easy to make use of.
And this final level is vital, as a result of taking photographs of extraordinarily dim objects trillions of miles away has, till lately, been a really arduous factor to do (understandably so).
I converse from expertise right here, as a result of I started my astro journey greater than a decade in the past by hooking up a mirrorless digicam to a telescope on a monitoring mount. It labored, and I captured some nice photographs, nevertheless it was an actual time-, money- and effort-sink, with arcane software program to navigate, heavy gear to lug round, and a seemingly endless procuring listing of recent equipment to shell out for.
The Seestar S30 Professional is about as far-off from that as you possibly can think about; it’s small, gentle, super-simple to arrange, and simply does its factor effectively, leaving you free to benefit from the outcomes. It’s a revolution — like we jumped from growing movie in a darkroom to snapping a photograph in your iPhone in simply a few years.
That is the fourth sensible telescope I’ve used, following ZWO’s authentic Seestar S50, the very good Dwarflab Dwarf 3, and the Dwarf Mini; I’m within the technique of testing the latter proper now and might be writing about that very quickly.
All have their sturdy factors, but when I may solely personal one, it could be the S30 Professional. And no, the views don’t fairly rival being on the Artemis II mission and gazing on the darkish facet of the Moon, however they’re adequate for me.
Professional by identify, Professional by nature
At launch, the Seestar S30 Professional prices $599 / £649 / AU$999 — a not inconsiderable quantity, admittedly, however nonetheless far lower than what you’d have to spend on a person mount, ‘scope, digicam, and filters. Word, although, that inventory is at the moment restricted, with many shops reporting a wait time of a month or extra.
For that value, you get rather a lot — basically every little thing it is advisable take photographs of galaxies, nebulae, star clusters, the moon, the solar, and even daytime targets resembling birds.
The one factor you received’t simply be capable to seize with it’s a planet, as most are far too small (comparatively talking) to indicate up as greater than a dot. That’s true of most sensible telescopes, although, notably at this value.
The S30 Professional has a dual-camera setup, with one telephoto and one large lens. The 160mm telephoto is a high-quality 4-element apochromatic with a high-resolution 4K Sony IMX585 sensor, whereas the 6mm large digicam can be 4K and has a formidable 63-degree area of view.
Most of your taking pictures might be accomplished with the tele, which is itself a fairly wide-angle affair; it captures a a lot bigger part of the sky than the S50 or Dwarf Mini and a good bit greater than the Dwarf 3.
That is nice, because it makes it a lot simpler — and sooner — to shoot massive targets such because the Andromeda galaxy or Coronary heart Nebula without having to fiddle with mosaics (which entails taking pictures totally different bits of the picture individually, then stitching them collectively).
The draw back is that smaller targets might be, nicely, smaller within the body. However you will get round this to an extent by cropping — which in flip is made simpler by the truth that the pictures are 4K. Do observe, although, that the Seestar’s sensor is vertical reasonably than horizontal — so it’s higher for ‘tall’ targets than large ones. You may rotate it, however doing so will improve the time taken to get the complete picture.
The wide-angle digicam, in the meantime, serves a twin goal: it helps the S30 Professional’s tele lens discover its goal, and can be utilized for widefield pictures of the Milky Means.

The S30 Professional comes with a number of built-in filters, together with a dual-band filter that brings out coloration and element in nebulae, plus an exterior photo voltaic filter that clips on magnetically. You additionally get a reasonably good carrying case, plus a mini tripod and USB-C cable for charging it up.
Talking of charging, the S30 Professional has a 6,000mAh battery, which ZWO says is nice for about 6hrs of taking pictures. If something, I’d say that’s somewhat conservative, and it positively appears to empty battery extra slowly than the larger S50. Not that it issues an excessive amount of both manner, as a result of you’ll be able to merely plug in a conveyable energy pack to present it sufficient juice to final by way of the evening.
The 128GB of storage is twice the quantity you get with the S50 or Mini, and the identical as that within the Dwarf 3. This offers sufficient house to shoot a number of targets for a number of nights — every publicity, or ‘sub’, takes up 16.6MB, that means you possibly can match many 1000’s on there earlier than needing to delete some.
Measurement-wise, it’s rather more manageable than the reasonably hefty S50, which is itself a tiny little factor in comparison with a devoted astro mount and telescope. The S30 Professional weighs simply over 1.5kg — half a kilo lower than the MacBook Professional I’m typing this on — and will simply slot in a backpack for a visit out to a dark-sky spot.
It’s additionally actually, actually properly constructed: strong, quiet in use, and with a sexy matt white end. It’s apparent from the second that you just unpack it that it is a high quality product by way of and thru.
None of that will matter if the picture high quality was missing, although, so how does the S30 Professional fare in that regard? Nicely, I’m joyful to report that it’s not simply good — it’s unbelievable.
Bringing the heavens to life
Good telescopes work by rotating in time with the skies, so your goal stays centered, then taking plenty of comparatively brief photographs and ‘stacking’ them to convey out the element.
This stacking is one thing that’s wanted for all astrophotography, as a result of most topics are so far-off that sensors solely seize a really small quantity of their gentle, however numerous undesirable noise. Stacking will increase the signal-to-noise ratio to show a dim, fuzzy blob into a wonderful picture of, say, the majestic Rosette Nebula.
You may see it in motion under; it is a sped-up model, as a result of in complete I shot the Rosette for 2hrs utilizing 1-minute exposures, so captured 120 frames in complete — whereas this GIF is created from solely 13 photographs. However you get the thought.
One of many key benefits of sensible telescopes is that this stacking is completed mechanically because the telescope captures the info; you’ll be able to see the goal rising from the noise and getting brighter and extra detailed in your display, the longer you snap away. There’s an app for Android or iOS, and it really works notably nicely on iPad, the place the bigger show makes it simpler to see what’s taking place.
After all, you too can obtain the pictures — both the completed stack, or particular person exposures — after you’ve completed, then course of them individually within the likes of Photoshop or Lightroom, or utilizing specialist astrophotography software program resembling Pixinsight or Siril.
The outcomes once you do that may be unbelievable. Take the Rosette Nebula once more: on the left of the picture under, you’ll be able to see the completed stack because it got here out of the Seestar S30 Professional, full with a path from both a satellite tv for pc or aircraft; on the best, there’s the clear model created from particular person frames I stacked in Siril after which processed in Pixinsight.
Don’t have a laptop computer or desktop pc? No downside — as a result of you’ll be able to course of photographs throughout the Seestar app as an alternative. The outcomes received’t be fairly pretty much as good as for those who’ve accomplished it your self in specialist software program, however for instance, right here’s the Rosette Nebula once more, processed by the Seestar’s Deep Sky Stack function and in comparison with my Pixinsight model.
The wonders of the universe
I wasn’t ready to make use of the Seestar S30 Professional for the primary month I had it, as a result of the UK was being subjected to some sort of atmospheric torture recreation involving limitless banks of clouds and rain.
A confession: this will even have been my fault, as a result of all astronomers know {that a} new telescope at all times comes with a free reward of cloudy skies, and I’d simply taken possession of two, with the Dwarf Mini having been delivered quickly after the Seestar. Sorry, everybody!
Finally, the climate improved, and I acquired taking pictures — and shortly realized what this sensible ‘scope can do.
My first goal was the apparent one for late spring: M42, the Orion Nebula. This is likely one of the brightest nebulae and may even be seen with the bare eye; lookup on the evening sky and also you would possibly glimpse it, just under the three stars that comprise Orion’s Belt.
It solely took a couple of minutes for it to begin forming on my cellphone’s display, and an hour was lengthy sufficient to convey out the great purple and violet hues of the nebula’s central core. The picture under is definitely a composite of three nights’ value of pictures, totalling 2hrs 40 minutes, and with that stage of integration, you too can simply make out the little ‘Working Man’ nebula above it.

Different targets presently included the aforementioned Cone and Rosette nebulae, and one among my favorites — the Horsehead Nebula. The S30 Professional did a implausible job with every of those, with the IMX585 sensor and high quality glass combining to essentially convey out the daring colours, notably as soon as I’d processed them absolutely.
By mid-to-late March, we had been within the midst of galaxy season, with the Milky Means and its colourful nebulae principally out of sight and the targets consisting as an alternative of the spiral arms and glowing facilities of the likes of M51, the Whirlpool Galaxy.
These are usually not actually the S30 Professional’s forte; as I mentioned above, they’re typically too small to be nicely suited to the telescope’s FOV. However they’ll nonetheless make for hanging photographs, with the mix of a small galaxy in opposition to an unlimited backdrop of stars actually bringing the enormity of the universe into sharp reduction; I’m notably happy with how my shot of the stunning Needle Galaxy got here out, as an illustration.
Picture 1 of 5
I additionally took photographs of a number of star clusters, which the S30 Professional dealt with easily. The ‘scope’s high-quality glass actually helps to drag out the person stars — there are a number of hundred thousand within the M13 Nice Hercules Cluster, and although my photograph above can’t resolve all of them, it does an ideal job of capturing the dense cores.
And naturally I took some photographs of the moon and solar. My lunar shot is just not fairly up there with the picture taken by the Artemis II astronauts, nevertheless it’s mine, and I nonetheless adore it. As with galaxies, the S30 Professional isn’t ideally suited to the moon — the S50 offers a a lot nearer view — nevertheless it certain beats a smartphone.
The solar, in the meantime, may be photographed through the included exterior photo voltaic filter. This snaps on magnetically, and after that, you merely choose it within the app, anticipate the ‘scope to maneuver to its goal, then snap away.

Lastly, to essentially put the Seestar S30 Professional by way of its paces, I turned it in the direction of the Virgo Cluster. It is a galaxy-rich space of the heavens containing some 1,300-2,000 of the constructions. Many are too small (or reasonably, too far-off) to be captured by the Seestar S30 Professional, however I used to be astounded at simply what number of it did choose up.
For the shot under, I used the S30 Professional’s mosaic mode, which will increase the scale of the shot by as much as 2x. This isn’t typically one thing you’ll want to make use of, as a result of the S30 Professional has such a large area of view that the majority targets don’t require it, however it might probably add some additional drama to your imaging.
I’ve additionally included an annotated model that demonstrates simply what number of targets the S30 Professional was in a position to choose up right here — greater than 100 of them, although most are not more than dim, fuzzy blobs.
Picture 1 of 2
There are, in fact, many 1000’s of topics you possibly can {photograph} within the evening sky, with the perfect targets altering with the seasons.
Fairly quickly, as an illustration, the Milky Means might be again in view for me — which can convey into play the gorgeous Eagle Nebula and the colourful Veil Nebula, and the large Coronary heart and Soul Nebula. And no matter I find yourself taking pictures, it’ll be the S30 Professional that I flip to first.
