Is Canon RP Astrophotography as Spectacular as it Seems?

In natural light, most cameras can capture good-quality images. But some cameras don’t work well in low light.

Canon EOS RP is one of the better performers in low light photography, particularly astrophotography.

But how can you be certain that Canon RP astrophotography is the best option?

Astrophotography with the Canon EOS RP gives stunning images of the night sky. The H-Alpha sensitivity of the camera is 4x greater than the standard model. You’ll get a full format sensor with megapixels in the 26.2 range. The rotating touch screen display helps easy focus even with the camera pointed upwards.

Before making a decision to buy it, you must have more information about its capabilities. Allow us to make your search for an answer on the internet easier. 

Let’s get started!

A Look into Canon RP Astrophotography

The Canon EOS RP is a full-frame camera for beginners. This camera has been modified especially for astrophotography enthusiasts.

Star clusters, hazy objects, and even far-off galaxies can all be captured through this camera. Compared to the standard version, the red range’s sensitivity (H-Alpha Sensitivity) is four times higher.

This guarantee remains valid because the conversion is performed by Canon Service. You don’t run into a feature like this very frequently.

Key Features of Canon EOS RP

According to Canon, the RP packs full-frame mirrorless performance inside a compact, lighter-weight EOS R series frame. You can take your photos to the next level with it by exploring new creative possibilities.

However, don’t go out to take pictures with this camera and your amazing sky atlas just yet. Let’s take a look at what sets the EOS RP apart from the competition first-

Sensor and Image Quality:

A large full-frame sensor with a 26-megapixel resolution is included on the Canon RP. Due to its significant size, this sensor has outstanding high-ISO capabilities.

In this price range, the RP is among the finest in low-light performance. This is the reason astrophotographers favour this camera.  But sadly it’s not the same in the case of dynamic range.

When compared to modern Sony sensor technology, this sensor performs about two stops lower, which is significant. Many APS-C cameras perform better than it as well.

A high contrast environment may also need you to use exposure bracketing more frequently. The image quality is excellent right out of the box. For a long time, this has been Canon’s strong suit.

By default, the colours, especially the skin tones, appear balanced and natural. Algorithms for sharpening and noise reduction are not overbearing.

H-Alpha Sensitivity:

This camera’s sensor’s response has been stretched further towards the red end of the spectrum. This is done to allow the camera to capture the hydrogen-alpha (H-alpha) emission line.

H-alpha (deep red) produces a colour balance that is fairly close to nature. This is crucial for astrophotography as it raises the target nebulosity’s contrast.

Removing the filter improves red sensitivity by a factor of 4. But the autofocus and dust vibrator features are still available. 

The protective filter is kept in place, only the IR cut filter is removed. As a result, the sensor is not exposed to the surroundings.

Mount and Compatibility:

The full-frame mirrorless RF mount from Canon serves as the foundation for the EOS RP. It features a 54mm diameter and a 20mm short flange distance.

The EOS RP has a limited selection of native RF lenses. You have a choice between the 24-105mm f/4-7.1 IS and the 24-240mm f/4-6.3 IS. 

The 24-105mm f/4 IS  is also one of the basic zoom lenses. The  24-105mm with f/4 IS is usually preferred for better image quality.

Additionally, a few top-notch small prime lenses are compatible. Due to their compact size, the 85mm f/2 IS Macro creates a fantastic kit with RP.

Because of the close flange distance, it is also possible to adapt non-Canon lenses.

Focusing and Burst:

Dual Pixel autofocus is included on the EOS RP from Canon. This system uses artificial intelligence to provide on-sensor phase detection.

The focusing points are numerous and cover nearly the entire frame. This device excels in low light conditions thanks to its high sensitivity.

The tracking features are quite rudimentary. But the camera can reliably track subjects. But burst mode shooting is not the EOS RP’s strong suit

Video Features:

Although there are several restrictions, it can still shoot in 4K. You can only shoot at 24fps with a 1.7x crop and no autofocus. Both 10-bit output and Log profiles are missing.
But the scenario is better in Full HD. With a full autofocus track and no crop, you have a number of possibilities up to 1080/60p.

Surprisingly, the RP has a micro-HDMI connector with clear output, along with a headphone and microphone jack.

Body and Handling:

The EOS RP is among the smaller full-frame cameras ever manufactured. Its measurements are 133 mm x 85 mm x 70 mm. And its weight with the battery is 485 grams. 

Its build quality is good, as it is largely made of magnesium alloy. The weather-sealed nature of the camera allows it to operate in chilly, dusty, or rainy environments.

By entry-level standards, the EOS RP is properly equipped with controls. Two control wheels are positioned in an ergonomic way. On the top, there are also dials for the mode and on/off functions.

Additionally, there is a fantastic flip-out touchscreen on the back. The rotating and swivelling display enables easy focusing even once the camera is pointed upwards.

In terms of battery life, it is not very lengthy. One battery can yield approximately 200 shots before it runs out entirely. 

There is a wide range of connectivity choices. Additionally, Bluetooth connectivity with a phone allows for GPS geotagging.

Alternative Cameras 

The EOS RP occupies an odd position in the market. It mostly competes with mid-range M4/3 and APS-C cameras rather than full-frame ones.

But there are some comparable full-frame choices. The Canon EOS 6D MkII comes with similar features to EOS RP, with a more durable body. 

Not every Fuji camera, such as the Fuji x100v is suitable for astrophotography. But an APS-C camera that stands out for its stunning design is  Fujifilm X-T30

The video and JPG quality of the Fujifilm X-T30 is exceptional. These cameras have excellent low-light capabilities. And, with an ISO range of 160 to 12,800, it’s ideal for astrophotography. 

In this category, the Sony A6400 is the best pick for quick action. It has the best autofocusing technology among these cameras. It also has similar ergonomics to the RP. This choice of lens is quite adaptable.

It is ideal for various low-light settings, including landscape photography, vlogging, and video. It is also excellent for astrophotography.

If you don’t want to move on to an entirely different type of camera then you can just pick up the Canon EOS RP Mirrorless Full Frame Camera from Aliexpress. It’s almost the same as the original Canon RP, just a bit better. j

Final Verdict

The EOS RP is a superb compact camera for some tasks but a poor choice for others. Most of the RP’s benefits are restricted to its size and sensor. This is due to its lack of advanced functionality.

However, with the correct lenses, it’s a great option for low-light photography on a budget. For astrophotography lovers with longer-term goals, the RP is ideally suited. 

Frequently Asked Questions (FAQs)

Is Eye Detection Available on the Canon RP?

Yes, eye detection is available on the Canon RP. Eye AF is a built-in feature of the Canon RP for distinctive portraits. It’s Dual Pixel CMOS AF technology keeps the subject’s eyes in extremely crisp focus.

Can the Canon RP Capture 4K Video?

Yes, the Canon RP can capture 4K video. However, there’s a catch. The Canon RP can shoot in 4K at up to 25fps. But it tends to lose Dual Pixel and experiences a 1.76x crop. It can shoot at a maximum speed of 50 fps in 1080p without cropping.

Is Focus Stacking Available on Canon RP?

Yes, focus stacking is available on Canon RP. Canon RP has built-in automated focus bracketing to make it easier to capture focus-stacking images. You can program the camera to take the required number of shots at the preset focusing increments.

End Words

That’s all about Canon RP astrophotography. The Canon EOS RP is an excellent camera that can be adapted for astrophotography.

Nevertheless, there are certain drawbacks. But with practice, you will be able to master the techniques for astrophotography with this camera.

Till we meet again. Have fun photographing the night sky!
