ZWO ASI Planetary Astrophotography Cameras Review

I’ve always been fascinated by astrophotography, the intricate process of capturing the splendor of celestial bodies far beyond our atmospheric confines. There’s something magical about freezing a moment in the vast cosmos, bringing a piece of the universe straight into our hands. Today, I’m zooming in on the instruments that make this possible: planetary astrophotography cameras.

Unlike the point-and-shoot cameras or the smartphone lenses we use to snap photos of earthly subjects, these cameras are high-precision tools specifically engineered to capture planets with striking detail. The ability to reveal the subtlest of features on a planet’s surface turns these cameras into essential instruments for both hobbyists and professionals alike.

Among the stars of this specialized niche are ZWO astronomy cameras, known for their robust performance in capturing planetary images. In the following sections, I will compare and contrast three one-shot-color models from this acclaimed lineup – the ZWO ASI585MC, ASI715MC, and ASI664MC – to help astrophotography enthusiasts decide which camera could be their ideal co-pilot in their journey of cosmic exploration.

Aspects like sensor size, resolution, frame rate and others will be on the spotlight, ensuring you get a thorough understanding of what each camera can offer. In the end, the aim is to provide you with the knowledge to make an informed decision about which camera can best meet your stargazing ambitions.

Comparing Planetary Giants: ZWO ASI585MC, ASI715MC, and ASI664MC Cameras

I’m on the lookout for a reliable planetary camera and, likely, so are you. That’s why it’s crucial to compare the offerings out there. Enter the ZWO ASI585MC, ASI715MC, and ASI664MC cameras. These devices from ZWO are designed to meet the needs of avid stargazers and serious astrophotographers alike, but each has its unique traits.

When comparing astrophotography cameras, it’s not just about the megapixels. Sure, a high count can result in clearer pictures, but there’s more beneath the surface. Sensor size, frame rate, and sensitivity play pivotal roles in capturing planetary movements where every detail counts. I’ve got these factors covered for you.

First up, resolution. Both the ASI585MC and the ASI715MC boast resolutions close to 8.5 megapixels, promising crisp images of celestial bodies. But don’t overlook the ASI664MC with its 4.15-megapixel resolution. In some cases, fewer pixels with better quality can do wonders, especially on a smaller sensor. Pixel size also matters with both the 585 and 664 coming in at 2.9µm, while the 715 boasts a pixel size half as big at 1.45µm.

The frame rate is vital for planetary imaging where precision timing is everything. If Jupiter’s Great Red Spot is playing hide and seek, you’ll want a camera with a high frame rate to capture that elusive moment. The frame rates of these cameras might just make the difference in your astrophotography adventure. Both the 585 and the 715 have frame rates in the mid-40s, while the 664 has a frame rate of 95 fps.

And then there’s sensitivity. Planets don’t stand still, and they certainly don’t shine as bright as the moon. A sensitive camera sensor can capture the faint details of Saturn’s rings or the delicate cloud bands on Mars, even in less-than-ideal lighting conditions.

Don’t forget about the cooling systems, a feature often undervalued by beginners. If you’re going for long exposure shots, a camera’s cooling system can reduce noise significantly, preserving the quality of your captures over time.

These factors lay the groundwork for our next section, where I’ll dissect the specs of each camera. We’ll look closely at how the ZWO ASI585MC, ASI715MC, and ASI664MC cameras stand up under scrutiny and which one might be the ideal companion for your nights spent under the stars.

Deep Dive into Specifications: Dissecting the ZWO ASI Planetary Cameras

I find that specifications are like a road map for technology. They guide us to understand the capabilities and limitations of the devices we use. In the realm of planetary astrophotography, details matter. So, let’s look closely at the specifications of three ZWO cameras that are crafted for this delicate art.

The ZWO ASI585MC camera comes with a resolution of 8.29 megapixels, ensuring high-quality images. The 3840 x 2160 pixel Sony IMX585 sensor at its core is what helps in capturing sharp, crisp images. With a pixel size of 2.9 microns, this camera provides excellent sensitivity, making it a reliable choice for astrophotographers aiming to record finer details on planets. The efficiency of the sensor is an impressive 91%.

Moving on to the ZWO ASI715MC, with its 8.46 megapixel count and a pixel size of 1.45 microns, it offers a balance of resolution and sensitivity. This is further enhanced by its 3864 x 2192 pixel Sony IMX715 sensor, designed to be effective even in less-than-ideal lighting conditions common in astrophotography. The quantum efficiency is not quite as high at 80%.

Finally, the ZWO ASI664MC offers a 4.15-megapixel sensor housed within a smaller and more compact form factor. Its 2704 x 1536 pixel Sony IMX464 sensor, with a pixel size of 2.9 microns, is the largest of the 3 at 1 x 2.8”, and it serves the needs of those preferring larger pixels that can gather more light, an advantage when targeting specific planetary features.

Moreover, all three cameras come with the essential USB 3.0 interface for fast data transfer, which is crucial when working with high-resolution images at high frame rates. None of the cameras offer cooling. But with bright objects and CMOS sensors, noise is not significant, and each has virtually no amp glow to interfere.  Each model comes with its unique set of strengths, catering to a variety of astrophotography needs and preferences.

But specifications are just one part of the story. In the next section, we’ll explore real-life experiences and feedback from the astrophotography community to see how these cameras perform under the stars.
