Purchased this to replace my mirrorless camera and start EAA. Finally had a clear night to test it. Fantastic images of M33. Could even see it on a single 15 second sub. Very pleased with it and highly recommended. FLO fantastic as always.

The ZWO ASI533MC PRO camera arrived within 24 hours of ordering and was well packed. The camera looks like a nice piece of kit and a quality build but I've not been able to use use it yet because of our great British weather. I've still given 5 stars for FLOs good work.

Great service from the guys and rapid delivery (next day).
Being an Englishman there has been no clear nights to use my new camera so what this space.

Many thanks FLO.

As always, exemplary service from FLO, and Dave on the emails. The expected delivery date was bettered by two weeks! The camera itself is excellent; still getting to grips with it. Very different to my DSLRs!

I received my WZO ASI 533mc pro cooled colour camera within two days of ordering
well wrapped up and safely delivered by pure luck the skies cleared up that night
allowing some test shots and was I blown away . The first object visited was M31
beautiful lost for words then off we went into Cygnus ending up with M33 here I was
seeing objects that I knew but had only seen in Astronomy Magazines . Thank you
for all your help with this and in the past

Just had my asi 533mc-pro delivered ,i would just like to thank FLO for the good service and packaging great stuff,now just got to use it weather permitting. R.madley

I got this to replace my old Canon DSLR and have been even more impressed than i was expecting. On my first night, single subs have given me noticeably better results than stacked and calibrated DSLR frames and the lack of noise in the signal makes processing a real breeze. If you are considering this as an upgrade from a DSLR, dont think twice, just buy one now!

I tried this camera on three targets the Soul Nebula IC1848 at a focal length of 360mm, M31 Andromeda at a focal length of 650mm and M33 Triangulum at 650mm as well. I found the camera sensor performance to be good. However the sensor size and shape cropped the objects. Although I did use online framing calculators to see that the objects where OK in frame, the sensor size is rather small. This means that you have to pay very close attention to the camera orientation and your telescope focal length to ensure the images are not too cropped. For small targets its really good but for large targets you will need a short focal length or work on mosaics, which with UK weather is quite a challenge. The software connected first time, not problems. I only hand one issue where the camera didn't cool, but a restart of the camera and it came good. The image quality is good. It's not outstanding, but it is very good. I returned my camera because the sensor size is small and limiting.

A quality item that is well made and looks good. Time will tell how it performs, as due to poor weather conditions, I’ve not used it yet. I took a month of fully researching this and the 294MC Pro to finally decide on the 533MC Pro.I have high expectations that will hopefully be rewarded with good images when the weather improves. The square sensor is likely not to be to everyone’s liking, but there are trade-offs, advantages and disadvantages to be considered before making a final decision to purchase. I went with the 533MC Pro because it best suits a number of my telescopes, as well as zero amp glow, well depth, read noise etc. As usual, great service from FLO.

After imaging for a year with a Canon R6 I realised that going dedicated astro camera would be a huge advantage as I live in Zambia which can get really hot, so active cooling was a must. I bought the camera back in Europe months ago but first light was on my return to Zambia. After being used to spending hours trying to tease out detail in nebula the 533mc was a revelation. Bring the images into APP, calibrate and stack, across to Photoshop for a few tweaks and done. The camera exhibits no amp glow and with the small sensor size there is no vignetting on any of my lenses. In short so far I have only used dark frame calibration. I am very glad I went for this camera rather than the 294 (which I was considering but heard so many issues with calibration). I would really recommend this camera for people like me who are getting started with dedicated astro cameras. I image with an ASIair which obviously plays very nicely with this camera.
