ZWO ASI533mc Pro Review | Dedicated Astrophotography Camera

The ZWO ASI 533mc Pro is a cooled one-shot colour dedicated astronomy camera. Boasting a square sensor, high efficiency and rated as an entry level camera. In this video I'm going to share my feelings about this cool little camera.
Known as a "ColdMos" camera, this camera has two stage cooling for cleaner images and a nice small sensor for some interesting field of views and composition opportunities.
I have very much enjoyed my time with the camera, but has it really all been fun and games? Nothing is perfect and I'll tell you all about it.

Thank you for the Review. This is what I needed to hear. I have been in search for my First Astro Camera, and I think that I have landed on the one I will be getting. I have done other research on it as well, and it helps to hear your input on it. Thanks again for your review and what you do on the channel. 👊😎

[@johnadastra1754]

Hey! Great review! All the in and outs needed for deciding on an astro cam .Really liked the range of focal lengths and objects sizes covered. Would like to see this tech with some larger pixel sizes and slightly larger sensors for bigger scopes. Please keep the specifications heavy talks coming!

[@daverowe433]

Mine arrives in a few days time. I found your video extremely useful. You also tend to start talking about technical stuff I don’t understand which for me as a beginner astrophotographer (maybe somewhat surprisingly) is really useful because it directs me to areas I need to research.

[@5teveL1]

Great channel with some really good content. I've just started using the 533, I came from a dslr so had a lot to learn. I actually like the square sensor & lack of noise on longer eposures. I use it on my WO z61 & my 102mm Altair triplet depending on what I want to shoot, so far no complaints !

[@tomharbin1652]

Excellent video, Ruz. You're swaying me, for sure. That zero amp glow (within my budget) is really attractive. Your honesty honestly comes through in all your work. Honest. Keep up the tremendous work.

Thanks for this video review. I just pulled the plug on a ASI533MC Pro which will be going on my remote observatory which will use a 8" f4 Newt and HEQ5Pro with Belt Mod. Looking forward to using it under Bortle 2 skies. As my first dedicated Astronomy Camera, a move up from DSLR, this will do me for a little while until I can afford to go Mono. Although I do prefer LRGBHa images the RGB or RGGB should be useful for a little while. Keep the videos coming.

I've always liked square format (daylight) photography, so it made sense for my first cooled camera to be square format. I've it since a few months now and I'm really happy with it, sure 9Mpx isn't much compare to my dslr but it's plenty enough for me. For this price, it's the way to go. And the zero ampglow kills it, preprocessing is like butter with good calibration frames!

[@georges.5612]

Great review. I wanted to note that I was getting 19-20 fps with lunar shots using the ASI533MC. I did have have an issue with a different computer and my ASI183MM and its massive 20 MP sensor where I was only getting 2-3 fps for lunar images. There are a couple chokepoints that reduce speed, but the main culprit for me appeared to be the write speed of my hard disk. I was able to improve write speed with a solid state hard drive (NVMe). USB architecture can also be a chokepoint and there might not be easy options for upgrading this without changing laptops. Currently, I'm using an Intel NUC 7i5BNH as my data acquisition computer which has a second NVMe drive (2 TB) that handles everything both the 183 and 533 can throw at it.

Great review! Subscribed! Which camera would you recommend for camera lenses (180 or 135mm) and an 80mm refractor?

[@ant_hart]

Really really....and just one more..really ;) like how you show the different targets vs focal length mate! I’m considering this camera but still have a niggle the sq sensor might be a pain for some targets. Im coming from a 6d, I love it but once the (outdoor)temperature rises it gets noisy compared to what a cooled camera would so it’s time for a shopping trip! Do you think a OSC camera is the way to go ( UK skies) or would you jump in to mono? With all this free time lately I’ve been building a permanent pier so I’ll pretty much be able to get shooting the moment it’s dark every night weather permitting ...that’s the plan :) so that’s why I’m also considering mono. If there’s other cameras you’d recommend love to hear it mate 👍🏼 focal length of my ‘eventual scopes’ will be around 400-750mm mark, I’ve got a spacecat on the way ...scared to go much deeper atm!lol Cheers, Ant

[@captaindanield5827]

Great informational review. On the comparison to other cameras in the line it would be of interest to comment on the asi2600 and the asi071 in the comparison for size and technology of the imaging chip. I'm really enjoying the asi2600 ans recommend the 533 as well especially as they have no amp glow with hig sensitivity.

[@AstroFarsography]

Thanks very much. Also thanks for the suggestion for including the 071 and the 2600. My reasoning behind not including them was their price tag and sensor size really. I felt that comparing the 533 to those two cameras wouldn't have been a fair comparison as they're a lot more expensive and such. But maybe you're right in sensor technology. Going forwards I'll see about including other cameras in my comparisons!

[@tonyboutle1315]

Interesting, and a possibility for me I like the 294, but it is pricey, not too worried by the square format. The drop off on well depth against gain is a bit dodgy, hmm food for thought.

[@tomroberts3851]

Awesome video! Thank you!! Silly question, but can you cool to a specific temperature with the 533? I appreciate you can drop the chip temperature by, say, 20C but can you cool to a set -10C? I'm just asking because Id like to know if I can make one master dark at -10C and just use the same callibration dark files for a while ;) Second question is, would you pick this over the 294MC Pro? Thanks so much for the video!!!

[@matthilton8959]

Currently using a DSLR thinking of getting a cam along these line. Been looking at the 183 and this one. I have the Altair starwave 115 F7 , 805mm Focal length using a .79 reducer/flattering. What would be your tips for which cam. I'm not going to buy it on your say so. Just a view as you've experience of them. Cheers. Top vid again top.

[@stufftosee1746]

I chose the 183 for the cropping reasons you mentioned. The ampglow is real but i tend to crop to 5:4 or 4:3 which is usually enough to crop the rightside of the sensor out which is where the glow is really bad. Thanks for the unbiased review. Clear skies from the UK 😄

[@AstroFarsography]

The 183 definitely was a nice sensor to use so I'm sure you'll have fun with it! Have you tried AstroPixel Processor? When I was using the 183 I ended up using APP to help calibrate out the amp glow on it. I strive to be unbiased, clear skies from the Midlands in the UK! Haha

Couldn't find the Fat Thumbs Down, so just hit the thumbs up. Yes, square sensor is an instagram sensor. But it makes a lot of sense in that it's getting the best of the lens & field of view. The issue it that we rarely print like that - but why do print have to be rectangles? You probably will get a number of people tell you that you can successfully print much larger than 10 x 8. Anyway, 10 x 8 is old money. (I like old money). There are plenty of videos on this subject. The problem we gave is that when we create such a fine image, we don't want printing to make a mess of our work, but the pros know how to do it. I'm sure ZWO will be well pleased with this honest review. Great edit.

[@AstroFarsography]

Thanks for the thumbs up! Yeah I remember printing at 72 DPI and it just not looking good, so I printed at 300dpi and just looked so much better. I'm sure you can inflate the print larger but it's fine art print and I don't want to upscale my prints like that. Though I'm sure with some more research on my own, I'll find out more about printing. Square frames aren't even that common either. The ones I see readily available are 6x4, 8x10 or larger if you go into a photography/print store. I'm happy if people enjoy my review and leave with a better understanding and more informed on their choice, and if ZWO likes it too then that's just some icing on the cake :)

Hey there thank you 😊 Well I know exactly how good this camera is with the L-eNhance. The 294 is definitely an excellent camera, a lot of people use one to great results and I wanted one also. However the lack of amp glow cannot be understated and when I was buying my most recent cooled camera I chose the 533 over the 294 because of the lack of amp glow and sensitivity, plus the smaller chip was just about that sweet spot with my scope. I think you'd be happy with the 533 and L-eNhance.

Nice videos Pal, I love your enthusiasm. Have you tried dual sensor for autoguiding, surely the future.

Thanks John! Hmm, dual sensor? This is news to me! Can you tell me more?

[@johnybaby2]

@@AstroFarsography I am pretty new to astrophotography, I have been amazed by some 30 to 60 second exposures, so now gagging for a guiding system. This led me to look into dual sensors, one sensor for exposures and one for guiding, all through the same scope. Keep it simple and potentially cheeper as no guide scope. But apparently these cameras are expensive and what you can do with them is limited as filters etc effect the guiding. If a manufacturer (maybe Zwo) made a cheap one for beginners it would be perfect for images of galaxies, stars and bright nebular. I was just wondering if you had tried one of the more expensive ones.

[@AstroFarsography]

@@johnybaby2 ah sounds like you're describing Off-Axis Guiders. They're really good for long focal length instruments but they do need setting up correctly. As for filters and such affecting the guide camera, I'm not entirely sure but I think you'd put filters in after the OAG so the guide camera isn't interrupted. But I have no experience with them, I've never seen one up close not have I used one. So I can't really give you solid information unfortunately. Check out A.V Astronomy.

Good choice there mate. The ASI Software I'm unfamiliar with. But it sounds like you need to go into the settings and tell it to debayer the images to RGGB format. Once you stack the images also you'll probably see colour appear. Though when you take videos of sun/moon planets etc also ensure its not capturing a mono video.

Shooting at 1260mm, currently DSLR, looking to an astro cam. Thoughts on this vs the 294? Also trying to understand gain vs ISO. Something like gain at 100, has no meaning because I have no reference. Any links to a good explanation? Thanks

[@AstroFarsography]

At 1260mm with this camera will result in over sampling. I believe that, basically, means your image scale is so small and fine that you're going to need a very good mount and careful guiding. At that focal length the 294 is definitely the better match for the telescope. Samples correctly. I've not personally used the 294 though so I'm just going by the suitability calculator. astronomy.tools/calculators/ccd_suitability Gain is a measure of the camera's sensitivity almost. Similar to ISO. ISO is a measured value in stops and gain is a more flexible value. ISO also -should- be a standard measurement across any camera since it's from a organisation that designs standardized values. Higher gain is akin to higher ISO. Trying to compare them 1 for 1 isn't that straight forwards and I'm not going to pretend that I know all the ins and outs of it really. I found this article which made sense to me www.dpreview.com/forums/thread/2547876 I hope this helps!

Good to hear mate. You can use it on a 1370mm but without any reduction you'll have slight oversampling. Which means you'll need steady seeing and a very good mount. Also, the field of view is going to be very - very - tight. This camera has a 2.7x crop factor to consider. You'll get the core of M31, a star or two in M45 and that's about it

@@AstroFarsography Yea i took in consideration that i have an RC in fact and so i am planning to use it for far away dsos, i already saw it on astronomy tools , ofc closest dso such as Andromeda, pleiades or orion i won't be able to see almost anything if not sorta the core but i didn't know about the oversampling, is there anything i can do to fix that without buying a reducer?

Hi, why are you saying this sensor is suitable for focal length of 388mm to 1163mm?

[@AstroFarsography]

Hey there it's down to the pixel size of the sensor itself and something to do with sampling rate

[@flexable9256]

@@AstroFarsography Interesting, do you have some links about it?

[@AstroFarsography]

@@flexable9256 astronomy.tools and look for the CCD Suitability calculator. That's where I looked to get my figures. I don't necessarily have any links for further reading but there'll be lots on sites like Stargazers lounge and cloudy nights

So this vs the Altair 183C for $200 to $300 less?

[@AstroFarsography]

Altair was a very good camera, sensitive and huge megapixels. Better for shorter focal lengths than this but suffered mad amp glow/starburst that I could only ever calibrate out using AstroPixel Processor. It also has small wells so it's more suitable for lots of 2-3minute exposures. I was looking at both the ASI183 and this 533 to buy the other day and j settled on the 533 due to the amp glow and sensitivity plus more versatile pixel size

@@AstroFarsography Thanks for the quick reply. We really do appreciate everything you and the others are doing to help introduce us to this new (to me) hobby. Having never done any DSLR photography previously I am not familiar with "wells" but based on this comment, it sounds like the deeper they are, the longer exposure time is possible. According to Highpoint Scientific both are rated for the same 2000 seconds "maximum exposure" which is why I thought these two may be more closely matched but it now sounds like you are saying that was not the case IRL then, right? My objective for this color camera is more for showing others relatively quickly (e.g. be able to show friends and family what a 3-5 minute image) actually looks like 4 minutes after it is taken rather than hours later after processing. So perhaps for this quick "turn around" friends and family function perhaps I should just go cheaper with either a ASI385MC or even one of the Altair Hypercam 178MC models and buy a separate higher-end cooled mono camera for the longer duration stacking efforts that I would be doing late at night without an audience.

What's well depth?

[@AstroFarsography]

It basically describes how much light each pixel can take before saturating to white and losing all colour information

[@lachezarkrastev7123]

One real review - good job. Not like other astro "commersial" channels like AstroBackyard.

[@01157929]

Can you shoot Jupiter and Saturn with it?

[@AstroFarsography]

Should be able to with a good frame rate and region of interest!
