Is the ZWO ASI6200MM Pro worth it?

For narrowband imaging through a full-frame astrograph, yes: it is the biggest and best camera I have. On an APS-C telescope or for small targets, no: most of the 36 x 24 mm sensor goes to waste.

What telescope does the ASI6200MM Pro need?

One whose image circle covers the 43.3 mm diagonal. I used it on the ZWO FF110 (a 44 mm image circle) and the Askar SQA130 (55 mm).

How cold does it run?

I run it at a -10 C set point, and the 233 lights from my FF110 nights read -10.1 to -9.9 C. ZWO rates the cooling at 30 to 35 C below ambient.

How much integration went into my images?

From 36 minutes on the Rosette Nebula to 12 h 33 min on the Elephant's Trunk; the North America Nebula on the FF110 is four hours of 180 s subs in one night.

How big are the files?

Each 180 s sub is 9576 x 6388 pixels at 16 bits, 122 MB on disk, so a night of subs runs to many gigabytes.

ASI6200MM Pro or ASI2600MM Air?

Both use 3.76 micron pixels. The ASI6200MM Pro has 2.3 times the sensor area (61.2 against 26.1 megapixels); the ASI2600MM Air costs less and adds a built-in guide sensor and wireless control.

How much does the ASI6200MM Pro cost and where can I buy it?

The prices I recorded: £3,999 at First Light Optics (UK), awaiting stock; $3,999 (ZWO's 2025 P25 version) at Agena Astro (US), in stock; $3,999 at ZWO store (Global), in stock.

What have I not tested on the ASI6200MM Pro?

Read noise, full well and dark current: I quote ZWO figures and have not measured them.

Verdict: Worth a look

Written by Damon Scotting 8 min read

Buy it if

You image narrowband through a full-frame astrograph (an image circle of 44 mm or more) and want 62 megapixels of mono
You want room to crop: a 4K view cut from one frame still holds its detail
You already own a large filter wheel and 2 inch or 36 mm filters

Skip it if

You are starting out: a colour camera needs no filter wheel and no filters
Your telescope covers only APS-C, or your targets are small: most of the sensor goes to waste
You are budget conscious: my recommendation is an APS-C mono camera such as the ToupTek ATR2600MM

“It is a whopping 62 megapixels, meaning it is about 50% larger than an 8K image.”

How good is it? Here is what it captured

Eight targets

Veil Nebula, ZWO ASI6200MM Pro, Antlia 2.5 nm SHO

Integration: 1 h 30 min
Field: 2.9 x 1.9 degrees
Telescope: Askar SQA130
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM7
Target: Veil Nebula (NGC 6960 and NGC 6992)
Type: Supernova remnant
Location: Bortle 6.8 (in my garden)

You are looking at the aftermath of a star 20 times the size of our own Sun, which reached the end of its life about 10,000 years ago.

Elephant's Trunk Nebula, ZWO ASI6200MM Pro, Antlia 2.5 nm SHO

Integration: 1 h 30 min
Field: 3.3 x 2.2 degrees
Telescope: Askar SQA130
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM7
Target: Elephant's Trunk Nebula (IC 1396)
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

The Elephant Trunk Nebula is an absolute hall of famer when it comes to images of our night sky.

North America Nebula, ZWO ASI6200MM Pro, Antlia 2.5 nm SHO

Integration: 4 h 9 min (83 x 180 s)
Field: 2.7 x 1.8 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: North America Nebula (NGC 7000)
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

Now this is a great target to really stretch the muscles of this 62 megapixel camera.

It's high above the horizon all night, practically overhead, which means it was easy to get a whopping four hours of imaging time in just one night.

Heart Nebula, ZWO ASI6200MM Pro, Antlia 2.5 nm SHO

Integration: 1 h 9 min (23 x 180 s)
Field: 2.7 x 1.8 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: Heart Nebula (IC 1805)
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

I think the Heart Nebula looks genuinely impressive here and we've really maximised our field of view.

Andromeda Galaxy, ZWO ASI6200MM Pro, ZWO LRGB

Integration: 2 h 18 min (46 x 180 s)
Field: 2.7 x 1.8 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: Andromeda Galaxy (M 31)
Type: Galaxy
Location: Bortle 6.8 (in my garden)

It is certainly still picking up some very sharp details, particularly in these galactic bands.

Bode's and Cigar Galaxies, ZWO ASI6200MM Pro, LRGB

Integration: 1 h
Field: 3.2 x 2.1 degrees
Telescope: Askar SQA130
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM7
Target: Bode's and Cigar Galaxies (M 81 and M 82)
Type: Galaxies
Location: Bortle 6.8 (in my garden)

It's impossible to steal the show from the gorgeous spiralling arms of Bode's Galaxy and the unique chaotic structure of the Cigar Galaxy.

Rosette Nebula, ZWO ASI6200MM Pro, SHO

Integration: 36 min (12 x 180 s)
Field: 3.3 x 2.2 degrees
Telescope: Askar SQA130
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM7
Target: Rosette Nebula (NGC 2237)
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

Nevertheless, the fine structure is there to be seen, as well as its vibrant colours.

Dumbbell Nebula, ZWO ASI6200MM Pro, SHO

Integration: 42 min (14 x 180 s)
Field: 2.7 x 1.8 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: Dumbbell Nebula (M 27)
Type: Planetary nebula
Location: Bortle 6.8 (in my garden)

A target that realistically would have been perfectly framed by the ASI533 camera. The ASI6200 on the other hand just feels like a huge overkill.

Raw against finished

What is it for

The 6 targets, the raw combined stack against my finished image, each with its integration, the camera and the palette:

Elephant's Trunk Nebula (IC 1396): 1 h 30 min of light, ASI6200MM Pro, SHO, the raw combined stack with one automatic stretch
Heart Nebula (IC 1805): 1 h 9 min (23 x 180 s) of light, ASI6200MM Pro, SHO, the raw combined stack with one automatic stretch
North America Nebula (NGC 7000): 4 h 9 min (83 x 180 s) of light, ASI6200MM Pro, SHO, the raw combined stack with one automatic stretch
Andromeda Galaxy (M 31): 2 h 18 min (46 x 180 s) of light, ASI6200MM Pro, LRGB, the raw combined stack with one automatic stretch
Bode's and Cigar Galaxies (M 81 and M 82): 1 h of light, ASI6200MM Pro, LRGB, the raw combined stack with one automatic stretch
Rosette Nebula (NGC 2237): 36 min (12 x 180 s) of light, ASI6200MM Pro, SHO, the raw combined stack with one automatic stretch

Five things it is for

Narrowband through light pollution

Partnered with 2.5 nm narrowband filters, it isolates the light of the nebula so well that a hazy, light-polluted sky behaves like a far darker one.

Room to crop

The Cygnus Wall looks immense, sharp and structured, and I can crop into that area alone and still end up with a 4K image.

A whole galaxy in one frame

Because the sensor is full frame, a few angle adjustments fitted the entirety of the Andromeda Galaxy within the same field of view.

Space is big

The Andromeda frame did not feel like a 62 megapixel shot to me. The Heart Nebula definitely does: it gives me that space is big kind of feeling.

My best image

The Veil Nebula is my Mona Lisa, my starry night: the kind of image I would put up against the Hubble Space Telescope.

0:00 Can a $1,499 telescope produce exhibit worthy images?

0:02 These are all images I captured with ZWO's latest telescope, the FF110. 0:02 It cost $1,499. 0:07 And in today's video, we're going to see exactly why and what it's capable of. 0:11 I'm going to be pushing this telescope to its absolute limits by using the biggest and best camera I have to try and capture some exhibit worthy images from my back garden. 0:17 Is it possible? 0:20 Let's find out. 0:20 I'm Damon Scotting and this is Astronomical.

0:23 ZWO FF110 specs: 110mm, 766mm f/7, flat field, 44mm image circle

0:25 All right, so this is the ZWO FF110. 0:25 So that's 110 millimetres of aperture with a focal length of 766 millimetres. 0:33 So roughly an F ratio of F7. 0:35 The optics are a four element fully airspaced apochromatic design with one ED element. 0:40 And critically the field is flat natively. 0:42 There's no need for a separate flattener that you have to go out and buy and spend extra money on. 0:45 It provides a 44 mm image circle which covers a full-frame sensor corner to corner like the ASI 6200 monochrome camera which I'll be using in today's video.

0:53 Focuser, built in rotator, weight and length

0:56 The focuser is a 3-in rack and pinion with 10:1 dual speed. 0:58 And there is a 360° camera rotator built into the back with an engraved scale, which is the sort of thing you only appreciate when you have spent 20 minutes in the cold trying to square up a mosaic panel. 1:11 The optical tube alone weighs about 5.75 kilos, and that's closer to 6.8 when you have all of the rings and the handle included. 1:18 In terms of length, it is 664 mm at its shortest. 1:21 And then with the dew shield extended, we have about 815 mm at its full extension. 1:26 So first impressions, it is a very nice piece of kit. 1:30 Now, of course, we are dealing with just the optical tube here.

1:30 The rig: ASI6200MM Pro, AM3N mount, LRGB and 2.5nm narrowband filters

1:31 So in order to capture some images of our night sky, we do also need a camera and a mount. 1:35 So everything you are about to see has been shot with an ASI 6200 monochrome Pro, which is a full-frame mono camera mounted on top of an AM3N harmonic drive mount. 1:47 Now, another key element is that in today's video, I'm going to be imaging multiple different targets. 1:49 And in order to do so, I need to use different filter sets, and they include ZWO's LRGB filter set as well as Antlia's 2.5 nanometre narrowband filters. 2:00 Now, the cost of this combination is a long way north of the price of the tube itself, so this is certainly something to factor in. 2:05 The telescope really is the cheapest component in our setup today. 2:08 You can, of course, partner it with cheaper gear, but in today's video, I'm trying to demonstrate what its true capabilities are from a light polluted English garden. 2:17 So, without further ado, let's see how well it can cope. 2:19 All right, so first up is one of our nearest galaxies, Andromeda.

2:19 Andromeda Galaxy (M31), 2 hours LRGB, full frame field of view

2:22 You're going to have to excuse me using a huge camera like this that costs more than twice that of the telescope itself. 2:27 Because the telescope supports full-frame cameras, I thought it was smart to push it to its limits. 2:32 And because of that decision and a few angle adjustments, I've managed to fit the entirety of the Andromeda Galaxy within the same field of view. 2:38 I think this might be the first telescope I've reviewed so far this year that has an F ratio higher than five, which is notable here because this shot does not feel as bright as my other attempts, but it is certainly still picking up some very sharp details, particularly in these galactic bands. 2:53 This was a little over 2 hours worth of integration time with the ZWO 2 inch LRGB filter set. 2:57 I think it's done an adequate job, but to tell you the truth, at the moment, I am just whelmed.

3:03 Heart Nebula (IC 1805) in SHO with Antlia 2.5nm filters

3:04 Let's see if this changes with our next target, the Heart Nebula. 3:06 For this shot, I'm using the Uber Premium Antlia 2 and 1/2 nanometre filter set, which again, sorry, I'm aware this is a bit of a mismatch since these filters collectively cost more than this telescope. 3:18 But the goal was to cut through the dense light pollution in my area to give me some stunning vibrant displays. 3:23 And as you can start to see, that's precisely what I've ended up with here. 3:27 These colours are fantastic. 3:29 I weirdly felt that the Andromeda Galaxy shot didn't really feel like a 62 megapixel shot. 3:33 Well, this one definitely does. 3:36 This shot has really given me that damn space is big kind of feeling. 3:41 This was 30 minutes worth of hydrogen alpha shots, 30 minutes of O III shots, and 15 minutes of S II. 3:45 So yeah, I'm much happier with this capture. 3:50 I think the Heart Nebula looks genuinely impressive here, and we've really maximized our field of view. 3:53 Now, this is a great target to really stretch the muscles of this 62 megapixel camera.

3:54 North America Nebula (NGC 7000), 4 hours in one night, the Cygnus Wall

4:00 The North America Nebula provides a stunning stellar landscape. 4:02 It's high above the horizon all night, practically overhead, which means it was easy to get a whopping four hours of imaging time in just one night. 4:10 The Cygnus Wall down at the bottom here is looking immense, very sharp and structured. 4:15 You can crop into this area specifically and still end up with a 4K resolution image. 4:19 Yeah, I'm very happy with these central blue colours. 4:23 I think they are gorgeous. 4:24 But I still wouldn't give the shot the award for my favourite of this video.

4:28 Dumbbell Nebula (M27), a planetary nebula on a full frame sensor

4:28 Could that title perhaps go to our next deep sky object? 4:30 This is the Dumbbell Nebula, a target that realistically would have been perfectly framed by the ASI 533 camera. 4:36 The ASI 6200, on the other hand, just feels like a huge overkill. 4:42 This target is really fun for bringing out the fainter nebulosity that is otherwise invisible in the visible spectrum of light that we can observe. 4:50 And it has most definitely done that. 4:52 But perhaps I've skimped a little bit on the integration time. 4:54 And as a result, the colours of this nebula have suffered. 4:58 Normally, there's a nice hint of these red and orange colours, but I've just failed at making them pop here. 5:04 The Dumbbell Nebula is a planetary nebula, which means you're not looking at the explosive death of a massive star. 5:08 Instead, you're watching the relatively slow demise of a star a bit bigger than our own as it sheds its outermost layers whilst knocking on Death's door and beginning its demise into a lowly white dwarf star.

5:18 Elephant's Trunk Nebula (IC 1396), 3 hours, the crown jewel

5:18 A little underwhelming perhaps, but fear not, for I have saved the very best till last. 5:26 This is the Elephant Trunk Nebula. 5:26 And if you're a fan of stunning colour palettes, it doesn't get much better than this shot right here. 5:31 With 3 hours worth of integration time, the details and structures here are pinpoint. 5:35 It's sharp and well framed. 5:38 It is however just a shame about that stupid bloody satellite trail. 5:42 I know half of you have already spotted it. 5:44 So to the half who hadn't, I apologize for spoiling this shot. 5:48 I think it ticks all the boxes. 5:50 The shot is stunning. 5:50 is both vibrant and sharp, whilst also feeling like an epic 62 megapixel shot of our night sky. 5:58 This is definitely the crown jewel from today's video. 6:00 The kind of back garden shot that you frame in your office.

6:04 Verdict after 35 hours with the FF110

6:04 Yeah, not bad for a $1,499 telescope. 6:07 Yeah. 6:07 Okay, so what do we think? 6:10 I spent about 35 hours in total with this telescope over the course of a couple of months, and I've really enjoyed it. 6:15 In fact, I've been using it quite a lot to image the sun as well. 6:19 The FF110 telescope is just one telescope that's part of a much larger range recently released by ZWO. 6:25 So, if you do already own one of these telescopes, part of this range, then please let me and countless others know in the comments down below about your own personal experience. 6:32 Based on my time so far, I think it's a decent addition to the astrophotography market. 6:37 If you'd like to purchase one for yourself, then you can find direct product links in the description down below. 6:41 Thanks for watching. 6:41 I'm Damon Scotting and this was astronomical.

74/100 Stars for Your Buck

Pros

62 megapixels of full-frame mono: I can crop a 4K view of the Cygnus Wall out of one frame and keep the detail.
With 2.5 nm narrowband filters it pulled 12 hours of the Elephant's Trunk and 3 hours of the Veil out of a light-polluted sky.
The field holds the whole Andromeda Galaxy at 765 mm and a galaxy group with room to spare at 619 mm.
It held the -10 C set point on every sub: my 233 FF110 lights read -10.1 to -9.9 C.
Zero amp glow, 0.86 e- read noise and a native 16-bit ADC on the current model.

Cons

Overkill on small targets: the Dumbbell Nebula would have been perfectly framed by an ASI533, and here it sits small in a huge field.
It costs more than twice the ZWO FF110 I used it on, and the narrowband filters cost more again.
Mono means a filter wheel and full-size filters: every colour image I made with it here is built from separate H, S and O, or L, R, G and B, subs.
Each 180 s sub is a 122 MB file (9576 x 6388 at 16 bits), so storage fills fast.
It needs a telescope whose image circle covers a 43.3 mm diagonal to use the whole sensor.

The biggest and best camera I have.

Start with a colour camera: mono needs a filter wheel, filters and a separate run through each filter for one colour image.

Do not upgrade unless your telescope covers full frame: the pixels are the same 3.76 microns, only the field grows.

Imager of small targets

Small targets sit small: the Dumbbell Nebula looked lost in the field at 765 mm.

Budget-conscious mono imager

Skip

My recommendation is the ToupTek ATR2600MM: the same pixel size on an APS-C sensor for well under half the price.

Imager who wants one camera for the big nebulae

One 62 megapixel frame covers a whole nebula complex and still crops to a 4K view.

Is the ZWO ASI6200MM Pro worth it? For narrowband imaging through a full-frame astrograph, yes: it is the biggest and best camera I have. On an APS-C telescope or for small targets, no: most of the 36 x 24 mm sensor goes to waste. What I captured ↓
What telescope does the ASI6200MM Pro need? One whose image circle covers the 43.3 mm diagonal. I used it on the ZWO FF110 (a 44 mm image circle) and the Askar SQA130 (55 mm). The specifications and the comparison table ↓
How cold does it run? I run it at a -10 C set point, and the 233 lights from my FF110 nights read -10.1 to -9.9 C. ZWO rates the cooling at 30 to 35 C below ambient. Tested numbers and the download ↓
How much integration went into my images? From 36 minutes on the Rosette Nebula to 12 h 33 min on the Elephant's Trunk; the North America Nebula on the FF110 is four hours of 180 s subs in one night. What I captured ↓
How big are the files? Each 180 s sub is 9576 x 6388 pixels at 16 bits, 122 MB on disk, so a night of subs runs to many gigabytes. Tested numbers and the download ↓
ASI6200MM Pro or ASI2600MM Air? Both use 3.76 micron pixels. The ASI6200MM Pro has 2.3 times the sensor area (61.2 against 26.1 megapixels); the ASI2600MM Air costs less and adds a built-in guide sensor and wireless control. The specifications and the comparison table ↓
How much does the ASI6200MM Pro cost and where can I buy it? The prices I recorded: £3,999 at First Light Optics (UK), awaiting stock; $3,999 (ZWO's 2025 P25 version) at Agena Astro (US), in stock; $3,999 at ZWO store (Global), in stock. A record, not a live price The verdict, the readers and the sellers ↓
What have I not tested on the ASI6200MM Pro? Read noise, full well and dark current: I quote ZWO figures and have not measured them.
