Does the ZWO FF110 need a field flattener?

No. The field is flat natively, and ZWO quotes a 44 mm image circle: enough for a full-frame sensor.

Is the ZWO FF110 a quadruplet?

The optics are a 4 element fully air spaced apochromatic design with one ED element. ZWO does not publish the grade of the ED glass.

What camera, mount and filters did you use with the FF110?

Everything on this page was shot with the ZWO ASI6200MM Pro, a 62 megapixel full-frame mono camera, on the ZWO AM3N harmonic mount, through ZWO's 2 inch LRGB set and Antlia's 2.5 nm narrowband filters.

How heavy and how long is the ZWO FF110?

ZWO's figures: 5.74 kg for the tube and 6.76 kg with the handle, rings and dovetail; 664 mm at its shortest and 815 mm with the photo tube and dew shield extended.

What mount does the ZWO FF110 need?

With a camera, a guide scope and accessories the whole rig comes to about 9 kg, so it wants a mount rated well above that without a counterweight, such as the JUWEI-17 at 13 kg. I imaged with it on the ZWO AM3N with a counterweight.

Is the ZWO FF110 good for galaxies like Andromeda?

For the big ones, yes: the whole Andromeda Galaxy and its two companions fit the 2.70 x 1.80 degree field on a full-frame sensor. At f/7 it needs more integration than a fast astrograph; mine was 2 h 18 min of LRGB.

How much does the ZWO FF110 cost and where can I buy it?

The prices I recorded: £1,499 at First Light Optics (UK), awaiting stock; $1,499 at Agena Astro (US), in stock; $1,499 at ZWO store (Global), listed.

What have I not tested on the FF110?

Guiding, corner stars and tilt, flats and vignetting, and visual use: not tested.

Stars for Your Buck 73/100

Reviewed 2 Sep 2026 Updated 29 Sep 2026

Rank: #22 of 42 telescopes
Verdict: Worth a look

Written by Damon Scotting 8 min read

Buy it if

You image narrowband from a light-polluted garden and want a flat full-frame field without a flattener.
You already own the mount, the mono camera and the filters, and want a bigger refractor in the ZWO ecosystem.

Skip it if

The tube would be the first and cheapest part of a rig you do not own yet.
You already own a faster 100 mm class astrograph and want a brighter, not a sharper, result.

“The ZWO FF110 is a welcome addition to the astrophotography market. It scored 73 on my Stars for your buck rating system, largely thanks to its sharp images and relatively affordable cost. However, its hefty size might make it a difficult choice for some stargazers.”

In the hand

How good is it? Here's what I captured

Five targets

M 31 Andromeda Galaxy, ASI6200MM Pro, LRGB

Integration: 2 h 18 min (46 x 180 s)
Field: 2.70 x 1.80 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: M 31 Andromeda Galaxy
Type: Galaxy
Location: Bortle 6.8 (in my garden)

First up is one of our nearest galaxies, Andromeda. You will have to excuse me using a huge camera like this that costs more than twice that of the telescope itself. Because the telescope supports full frame cameras I thought it was smart to push it to its limits. Because of that decision and a few angle adjustments I managed to fit the entirety of the Andromeda galaxy within the same field of view.

This was a little over 2 hours worth of integration time with the ZWO 2 inch LRGB filter set.

IC 1805 Heart Nebula, ASI6200MM Pro, SHO

Integration: 1 h 15 min (25 x 180 s)
Field: 2.70 x 1.80 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: IC 1805 Heart Nebula
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

For the Heart Nebula I used the premium Antlia 2.5 nm filter set, which again is a bit of a mismatch since these filters collectively cost more than this telescope. But the goal was to cut through the dense light pollution in my area to give me some stunning vibrant displays, and that is precisely what I have ended up with here. These colours are fantastic.

I weirdly felt that the Andromeda Galaxy shot did not really feel like a 62 megapixel shot. Well, this one definitely does. This shot has really given me that space is big kind of feeling. This was 30 minutes worth of hydrogen alpha, 30 minutes of OIII and 15 minutes of SII. I am much happier with this capture; I think the Heart Nebula looks genuinely impressive here and we have really maximised our field of view.

NGC 7000 North America Nebula, ASI6200MM Pro, SHO

Integration: 4 h 18 min (86 x 180 s)
Field: 2.70 x 1.80 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: NGC 7000 North America Nebula
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

The North America Nebula is a great target to really stretch the muscles of this 62 megapixel camera. It provides a stunning stellar landscape and it is high above the horizon all night, practically overhead, which made it easy to build up 4 hours of imaging time. You can crop into this area specifically and still end up with a 4K resolution image. I am very happy with these central blue colours, I think they are gorgeous. But I still would not give this shot the award for my favourite of the review.

M 27 Dumbbell Nebula, ASI6200MM Pro, SHO

Integration: 42 min (14 x 180 s)
Field: 2.70 x 1.80 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: M 27 Dumbbell Nebula
Type: Planetary nebula
Location: Bortle 6.8 (in my garden)

The Dumbbell Nebula is a target that realistically would have been perfectly framed by the ASI533 camera; the ASI6200 just feels like huge overkill. This target is really fun for bringing out the fainter nebulosity that is otherwise invisible in the visible spectrum, and it has most definitely done that. But perhaps I skimped a little on the integration time, and as a result the colours of this nebula have suffered. A little underwhelming perhaps.

IC 1396 Elephant's Trunk Nebula, ASI6200MM Pro, SHO

Integration: 3 h 3 min (61 x 180 s)
Field: 2.70 x 1.80 degrees
Telescope: ZWO FF110
Camera: ZWO ASI6200MM Pro
Mount: ZWO AM3N
Target: IC 1396 Elephant's Trunk Nebula
Type: Emission nebula
Location: Bortle 6.8 (in my garden)

I saved the very best till last. This is the Elephant's Trunk Nebula, and if you are a fan of stunning colour palettes it does not get much better than this shot. With 3 hours worth of integration time the details and structures here are pinpoint; it is sharp and well framed. It is however just a shame about that stupid satellite trail. I know half of you have already spotted it, so to the half who had not, I apologise for spoiling this shot.

I think it ticks all the boxes: the shot is stunning, it is both vibrant and sharp whilst also feeling like an epic 62 megapixel shot of our night sky. Not bad for a $1,499 telescope.

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

0:00 These are all images I captured with the ZWO's latest telescope, the FF110. 0:00 It cost $1499 and in today's video we're going to see exactly why and what it's capable of. 0:07 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. 0:15 Is it possible? 0:15 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

0:23 Alright, so this is the ZWO FF110. 0:23 So that's 110mm of aperture with a focal length of 766mm, so roughly an F ratio of F7. 0:34 The optics are a 4 element fully air spaced apochromatic design with one ED element. 0:39 And critically, the field is flat natively. 0:39 There's no need for a separate flattener that you have to go out and buy and spend extra money on. 0:47 It provides a 44mm image circle which covers a full frame sensor corner to corner like ASI6200 monochrome camera which I'll be using in today's video. 0:53 The focuser is a 3 inch rack and pinion with 10 to 1 dual speed and there is a 360 degree 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.

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

1:08 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 664mm at its shortest and then with the dew shield extended we have about 815mm at its full extension. 1:24 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

1:32 So in order to capture some images of our night sky we do also need a camera and a mount. 1:37 So everything you are about to see has been shot with an ASI6200 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 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. 1:56 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. 2:06 The telescope really is the cheapest component in our setup today. 2:06 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. 2:14 So without further ado let's see how well it can cope. 2:19 Alright so first up is one of our nearest galaxies, Andromeda. 2:19 You're gonna have to excuse me using a huge camera like this that costs more than twice that of the telescope itself.

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

2:28 Because the telescope supports full frame cameras I thought it was smart to push it to its limits 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. 2:36 I think this might be the the first telescope I reviewed so far this year that has an f-ratio higher than 5, 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. 2:50 This was a little over 2 hours worth of integration time with the ZWO 2 inch LRGB filter set. 2:55 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

3:05 Let's see if this changes with our next target, the Heart Nebula. 3:08 For this shot I'm using the uber premium Antlia 2.5nm 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. 3:24 And as you can start to see, that's precisely what I've ended up with here. 3:28 These colours are fantastic. 3:30 I weirdly felt that the Andromeda Galaxy shot didn't really feel like a 62 megapixel shot. 3:36 Well, this one definitely does. 3:37 This shot has really given me that space is big kind of feeling. 3:37 This was 30 minutes worth of hydrogen alpha shots, 30 minutes of OIII shots and 15 minutes of SII. 3:48 So yeah, I'm much happier with this capture. 3:48 I think the heart nebula looks genuinely impressive here and we've really maximised our field of view.

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

3:55 Now this is a great target to really stretch the muscles of this 62 megapixel camera. 4:00 The North America Nebula provides a stunning stellar landscape. 4:00 It's high above the horizon all night, practically overhead, which means it was easy to get a whopping 4 hours of imaging time in just one night. 4:09 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, I think they are gorgeous. 4:23 But I still wouldn't give this shot the award for my favourite of this video. 4:26 Could that title perhaps go to our next deep sky object this is the Dumbbell Nebula, a target that realistically would have been perfectly framed by the ASI533 camera.

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

4:36 The ASI6200 on the other hand just feels like a huge overkill. 4:36 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 and it has most definitely done that but perhaps I've skimped a little bit on the integration time and as a result the colours of this nebula have suffered. 4:57 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. 5:07 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

5:21 A little underwhelming perhaps, but fear not, for I have saved the very best till last. 5:25 This is the Elephant Trunk Nebula, and if you're a fan of stunning colour palettes it doesn't get much better than this shot right here. 5:33 With 3 hours worth of integration time, the details and structures here are pinpoint, it's sharp and well framed. 5:37 It is however just a shame about that stupid satellite trail. 5:42 I know half of you have already spotted it, so to the half who hadn't, I apologise for spoiling this shot. 5:46 I think it ticks all the boxes, the shot stunning, it's both vibrant and sharp whilst also feeling like an epic 62 megapixel shot of our night sky. 5:57 This is definitely the crown jewel from today's video, the kind of back garden shot that you frame in your office. 6:03 Yeah, not bad for a $1499 telescope. 6:03 Yeah. 6:03 Okay so what do we think, I spent about 35 hours in total with this telescope over the course of a couple of months and I've really enjoyed it, in fact I've been using it quite a lot to image the sun as well.

6:04 Verdict after 35 hours with the FF110

6:19 The FF110 telescope is just one telescope that's part of a much larger range recently released by ZWO. 6:23 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. 6:33 Based on my time so far I think it's a decent addition to the astrophotography market. 6:33 If you'd like to purchase one for yourself then you can find direct product links in the description down below. 6:40 Thanks for watching, I'm Damon Scotting, and this was Astronomical.

Should you buy it?

73/100 Stars for Your Buck

Pros

Critically, the field is flat natively: there is no separate flattener to buy.
“The focuser is a 3 inch rack and pinion with 10 to 1 dual speed, and there is a 360 degree camera rotator built into the back with an engraved scale.”
The Cygnus Wall looks immense: very sharp and structured.
The Elephant's Trunk is the crown jewel: the kind of back-garden shot you frame in your office.

Cons

The tube alone weighs about 5.75 kg, closer to 6.8 kg with the rings and handle.
It is 664 mm long at its shortest and about 815 mm with the dew shield extended.
At f/7 it is slower than the fast astrographs around it: my Andromeda frame does not feel as bright as my other attempts.

Based on my time so far I think it's a decent addition to the astrophotography market.

Who the FF110 is for

Full-frame mono imager

Buy

“It provides a 44 mm image circle which covers a full frame sensor corner to corner, like the ASI6200 monochrome camera I used.”

Narrowband imager under light-polluted skies

Buy

It frames the big emission nebulae whole on a full-frame sensor, and narrowband filters turn a town sky into vivid, sharp SHO frames.

Existing ZWO mount and camera owner

Buy

It adds a 110 mm full-frame refractor to the mount, camera and filters you already own.

Beginner with no mount, camera or filters yet

Skip

“The telescope really is the cheapest component in this setup.”

Owner of a fast 100 mm astrograph

Skip

Stay with what you have: at f/7 the FF110 gathers light more slowly than an f/4.8 Petzval such as the Askar SQA106.

Planet imager

Skip

At 766 mm the planets are small. My recommendation is the Celestron 8 EdgeHD.

How much does the ZWO FF110 cost and where can I buy it? The prices I recorded: £1,499 at First Light Optics (UK), awaiting stock; $1,499 at Agena Astro (US), in stock; $1,499 at ZWO store (Global), listed. A record, not a live price The verdict, the readers and the sellers ↓
Is the ZWO FF110 worth $1,499? It scored 73 out of 100 on my Stars for Your Buck board. The flat full-frame field and the sharp narrowband frames are the reasons to buy it; the weight and the f/7 ratio are the reasons to pause. The verdict, the readers and the sellers ↓
What have I not tested on the FF110? Guiding, corner stars and tilt, flats and vignetting, and visual use: not tested.
