The Cone Nebula is an immense pillar of fuel and dirt some seven light-years tall. It’s positioned 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 crimson mild. And proper now, it’s in my front room.
Or quite, it’s on my cellphone, in my hand, as I sit in my front room staring in marvel on the majesty of our galaxy. Anybody may have a look at images of the Cone Nebula at any time, in fact, however this isn’t only a photograph of the Cone Nebula — it’s a stay feed* of it taken by the good telescope quietly doing its factor in my again yard. That good telescope is the ZWO Seestar S30 Professional, and it’s really, breathtakingly superior.

Smarter than your common telescope
The Seestar S30 Professional is one in every of a brand new breed of good telescopes (Picture credit score: Future/TechRadar)
Good telescopes have been round for a couple of years and have been a complete game-changer for newbie astrophotographers reminiscent of myself. That is 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, digital camera, and filters, but in addition as a result of they’re so easy to make use of.
And this final level is essential, as a result of taking images of extraordinarily dim objects trillions of miles away has, till just lately, been a really onerous factor to do (understandably so).
I communicate 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 digital camera 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 unending purchasing record of recent equipment to shell out for.
The Seestar S30 Professional is about as far-off from that as you would think about; it is small, mild, super-simple to arrange, and simply does its factor effectively, leaving you free to benefit from the outcomes. It is a revolution — like we jumped from creating movie in a darkroom to snapping a photograph in your iPhone in simply a few years.
That is the fourth good telescope I’ve used, following ZWO’s unique Seestar S50, the very good Dwarflab Dwarf 3, and the Dwarf Mini; I am within the technique of testing the latter proper now and can be writing about that very quickly.
All have their robust factors, but when I may solely personal one, it could be the S30 Professional. And no, the views do not fairly rival being on the Artemis II mission and gazing on the darkish aspect of the Moon, however they’re ok for me.
Professional by identify, Professional by nature
The S30 Professional comes with a carrying case and a small tripod (Picture credit score: Future/TechRadar)
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, digital camera, and filters. Notice, although, that inventory is presently restricted, with many shops reporting a wait time of a month or extra.
What to learn subsequent
For that value, you get quite a bit — primarily every thing you have to take images of galaxies, nebulae, star clusters, the moon, the solar, and even daytime targets reminiscent of birds.
The one factor you will not simply be capable of seize with it’s a planet, as most are far too small (comparatively talking) to point out up as greater than a dot. That is true of most good telescopes, although, significantly at this value.
Right this moment’s finest ZWO Seestar S30 Professional offers
The S30 Professional has a dual-camera setup, with one telephoto and one vast lens. The 160mm telephoto is a high-quality 4-element apochromatic with a high-resolution 4K Sony IMX585 sensor, whereas the 6mm vast digital camera can also be 4K and has a powerful 63-degree area of view.
Most of your capturing can be performed 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 quicker — to shoot massive targets such because the Andromeda galaxy or Coronary heart Nebula while not having to fiddle with mosaics (which includes capturing completely different bits of the picture individually, then stitching them collectively).
The draw back is that smaller targets can be, properly, 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 photographs are 4K. Do notice, although, that the Seestar’s sensor is vertical quite than horizontal — so it is higher for ‘tall’ targets than vast ones. You possibly can rotate it, however doing so will enhance the time taken to get the complete picture.
The wide-angle digital camera, 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 Manner.

The S30 Professional comes with a number of built-in filters, together with a dual-band filter that brings out colour and element in nebulae, plus an exterior photo voltaic filter that clips on magnetically. You additionally get a quite 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 capturing. If something, I would say that is somewhat conservative, and it undoubtedly appears to empty battery extra slowly than the larger S50. Not that it issues an excessive amount of both approach, as a result of you may merely plug in a transportable energy pack to provide it sufficient juice to final by 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 gives sufficient house to shoot a number of targets for a number of nights — every publicity, or ‘sub’, takes up 16.6MB, that means you would match many hundreds on there earlier than needing to delete some.

Dimension-wise, it is far more manageable than the quite 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 am typing this on — and will simply slot in a backpack for a visit out to a dark-sky spot.
It is also actually, actually properly constructed: strong, quiet in use, and with a horny matt white end. It is apparent from the second that you simply unpack it that it is a high quality product by and thru.
None of that may matter if the picture high quality was missing, although, so how does the S30 Professional fare in that regard? Nicely, I am completely satisfied to report that it is not simply good — it is unimaginable.

Bringing the heavens to life
Good telescopes work by rotating in time with the skies, so your goal stays centered, then taking a number of comparatively quick images 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 mild, however quite a lot of 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 possibly can see it in motion beneath; it is a sped-up model, as a result of in whole I shot the Rosette for 2hrs utilizing 1-minute exposures, so captured 120 frames in whole — whereas this GIF is created from solely 13 photographs. However you get the thought.
This timelapse exhibits the Rosette Nebula regularly changing into extra detailed as exposures are added (however closely sped up in comparison with actuality) (Picture credit score: Future/TechRadar)
One of many key benefits of good telescopes is that this stacking is completed routinely because the telescope captures the info; you may see the goal rising from the noise and getting brighter and extra detailed in your display screen, the longer you snap away. There’s an app for Android or iOS, and it really works significantly properly on iPad, the place the bigger show makes it simpler to see what’s occurring.
In fact, you can even obtain the photographs — both the completed stack, or particular person exposures — after you’ve got completed, then course of them individually within the likes of Photoshop or Lightroom, or utilizing specialist astrophotography software program reminiscent of Pixinsight or Siril.
The outcomes while you do that may be unimaginable. Take the Rosette Nebula once more: on the left of the picture beneath, you may 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 airplane; on the proper, there’s the clear model created from particular person frames I stacked in Siril after which processed in Pixinsight.
Haven’t got a laptop computer or desktop laptop? No drawback — as a result of you may course of photographs throughout the Seestar app as a substitute. The outcomes will not be fairly pretty much as good as in case you’ve performed it your self in specialist software program, however for example, here is 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 in a position 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 type of atmospheric torture sport involving countless banks of clouds and rain.
A confession: this may occasionally 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 would just taken possession of two, with the Dwarf Mini having been delivered quickly after the Seestar. Sorry, everybody!
Finally, the climate improved, and I acquired capturing — and shortly realized what this good ‘scope can do.
My first goal was the plain one for late spring: M42, the Orion Nebula. This is without doubt one of the brightest nebulae and might even be seen with the bare eye; search for 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 screen, and an hour was lengthy sufficient to convey out the fantastic crimson and violet hues of the nebula’s central core. The picture beneath is definitely a composite of three nights’ price of pictures, totalling 2hrs 40 minutes, and with that stage of integration, you can even simply make out the little ‘Working Man’ nebula above it.

Whether or not you assume it really resembles a monkey’s head is a special matter(Picture credit score: Future/TechRadar)The Jellyfish Nebula is the stays of a supernova. It is a powerful goal for a sensible scope, and I would most likely have wanted greater than the 70 minutes of exposures I took right here (Picture credit score: Future/TechRadar)
Different targets right now included the aforementioned Cone and Rosette nebulae, and one in every of my favorites — the Horsehead Nebula. The S30 Professional did a unbelievable job with every of those, with the IMX585 sensor and high quality glass combining to essentially convey out the daring colours, significantly as soon as I would processed them absolutely.
By mid-to-late March, we had been within the midst of galaxy season, with the Milky Manner and its colourful nebulae principally out of sight and the targets consisting as a substitute of the spiral arms and glowing facilities of the likes of M51, the Whirlpool Galaxy.
These should not actually the S30 Professional’s forte; as I stated above, they’re typically too small to be properly suited to the telescope’s FOV. However they will nonetheless make for placing photographs, with the mixture of a small galaxy towards an unlimited backdrop of stars actually bringing the enormity of the universe into sharp reduction; I am significantly happy with how my shot of the stunning Needle Galaxy got here out, as an example.

(Picture credit score: Future/TechRadar)The well-known Leo Triplet options three galaxies(Picture credit score: Future/TechRadar)Star clusters make an amazing goal — although comparatively small within the S30 Professional’s FOV, they stand out clearly and the good ‘scope does an amazing job of isolating particular person stars(Picture credit score: Future/TechRadar)
I additionally took images 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 cannot resolve all of them, it does an amazing job of capturing the dense cores.
And naturally I took some images of the moon and solar. My lunar shot shouldn’t be fairly up there with the picture taken by the Artemis II astronauts, nevertheless it’s mine, and I nonetheless find it irresistible. As with galaxies, the S30 Professional is not ideally suited to the moon — the S50 gives a a lot nearer view — nevertheless it certain beats a smartphone.
The solar, in the meantime, could be photographed by way of the included exterior photo voltaic filter. This snaps on magnetically, and after that, you merely choose it within the app, look ahead to the ‘scope to maneuver to its goal, then snap away.

The S30 Professional cannot seize the element you’d get from the Seestar S50, nevertheless it’s by no means a uninteresting goal(Picture credit score: Future/TechRadar)The S30 Professional comes with a photo voltaic filter for capturing the solar; you can also make out an honest quantity of element within the decrease right-hand aspect of the picture(Picture credit score: Future/TechRadar)
Lastly, to essentially put the Seestar S30 Professional by its paces, I turned it in direction of the Virgo Cluster. This can be a galaxy-rich space of the heavens containing some 1,300-2,000 of the constructions. Many are too small (or quite, too far-off) to be captured by the Seestar S30 Professional, however I used to be astounded at simply what number of it did decide up.
For the shot beneath, I used the S30 Professional’s mosaic mode, which will increase the scale of the shot by as much as 2x. This is not typically one thing you may want to make use of, as a result of the S30 Professional has such a large area of view that the majority targets do not require it, however it will 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 decide up right here — greater than 100 of them, although most are not more than dim, fuzzy blobs.
Picture 1 of two
A widefield mosaic shot of the Virgo cluster and its many galaxies…(Picture credit score: Future/TechRadar)…and an annotated model of the identical shot. Simply think about what number of stars and planets lurk inside it!(Picture credit score: Future/TechRadar)
There are, in fact, many hundreds of topics you would {photograph} within the evening sky, with the most effective targets altering with the seasons.
Fairly quickly, as an example, the Milky Manner can 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 capturing, it will be the S30 Professional that I flip to first.
