The Cone Nebula is an immense pillar of gasoline and mud 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 crimson gentle. And proper now, it’s in my front room.
Or slightly, it’s on my telephone, 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 picture of the Cone Nebula — it’s a reside 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
Good telescopes have been round for a number of years and have been a complete game-changer for novice astrophotographers corresponding to myself. That is partly as a result of they price a fraction of what you’d must 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 essential, as a result of taking photographs of extraordinarily dim objects trillions of miles away has, till not too long ago, been a really laborious 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 photos, however 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 checklist of latest package to shell out for.
The Seestar S30 Professional is about as far-off from that as you would think about; it is small, gentle, 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 excellent Dwarflab Dwarf 3, and the Dwarf Mini; I am within the technique of testing the latter proper now and shall be writing about that very quickly.
All have their robust factors, but when I may solely personal one, it will 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 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 must 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.
What to learn subsequent
For that value, you get loads — basically every thing you should take photographs of galaxies, nebulae, star clusters, the moon, the solar, and even daytime targets corresponding to 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, notably at this value.
Immediately’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 digicam can also be 4K and has a powerful 63-degree subject of view.
Most of your taking pictures shall be completed with the tele, which is itself a reasonably 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 giant targets such because the Andromeda galaxy or Coronary heart Nebula without having to fiddle with mosaics (which entails taking pictures completely different bits of the picture individually, then stitching them collectively).
The draw back is that smaller targets shall be, properly, smaller within the body. However you may get round this to an extent by cropping — which in flip is made simpler by the truth that the photographs are 4K. Do observe, although, that the Seestar’s sensor is vertical slightly 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 total 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 photographs of the Milky Approach.

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 slightly 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 sweet for about 6hrs of taking pictures. If something, I might say that is a little bit conservative, and it positively 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’ll be able to merely plug in a transportable energy pack to provide 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 supplies sufficient house to shoot a number of targets for a number of nights — every publicity, or ‘sub’, takes up 16.6MB, which means you would match many hundreds on there earlier than needing to delete some.
Measurement-wise, it is rather more manageable than the slightly 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.
