Canon RP for Astrophotography – Settings & Some Tips To Get You Started

  • Post author:

Yes, the Canon EOS RP is a good camera for astrophotography, with various capabilities that make it ideal for photographing the night sky. Here’s a list of the main features for astrophotography I have encountered:

  • Full-Frame Sensor: The EOS RP has a full-frame sensor, allowing it to capture more details and perform better in low-light conditions, which is essential for astrophotography.
  • Compact and Lightweight: Because of its compact size and weight, it is an ideal option for astrophotographers who may need to travel to various sites or trek to locate the best position to capture the night sky.
  • Focus Bracketing and Intervalometer: These capabilities may let you capture a series of photographs with varying focus points or create time-lapse sequences, both of which are important in astrophotography.
  • Vari-Angle LCD Screen: The Vari-Angle LCD screen allows for variable orientation, making it simpler to frame images, particularly when the camera is placed on a tripod at different angles.
  • Similar Sensor to Canon 6D Mark II: The EOS RP has the same sensor as the Canon 6D Mark II, a camera recommended for astrophotography, implying similar performance while photographing celestial views.
  • User-Friendly Interface: The camera’s well-organized menu and simple operation make it suitable for both beginners and expert photographers wishing to explore astrophotography.
  • Astrophotography Settings: The camera has manual settings for astrophotography, such as bulb mode, wide aperture choices, high ISO capability, RAW recording, and manual focusing.
  • Battery Life: Although the battery life is not the longest, it should be enough for most night sky photography sessions. Extra batteries are recommended for longer sessions.


  • Lightest, smallest full-frame EOS camera
  • RF mount compatible with RF lenses and EF/EF-S lenses with optional mount adapter
  • High image quality with 26.2 Megapixel Full-frame CMOS Sensor and DIGIC 8 Image processor
  • Dual pixel CMOS AF for fast and accurate auto focus
  • Use the EOS Utility Webcam Beta Software (Mac and Windows) to turn your Canon camera into a high-quality webcam, or do the same using a clean HDMI output.

These are some of the photos I have personally shot:

Due to the fact that its sensor is similar to the one found in the Canon 6D Mark II, you may expect results that are equal.

One of the cameras that Roger Clark recommends for use in astronomical photography is the Canon 6D Mark II, which may be found on his website. Because of this, I am able to say with absolute certainty that the Canon EOS RP will provide the same level of performance in a substantially more compact form factor.

In a similar vein, the Canon EOS RP is a fast and simple camera to use. The menu is really nicely arranged, and it is not difficult to understand what you are supposed to be doing.

All of the main settings are accessible, in addition to a few extra options for those individuals who are interested in expressing their creativity via their astrophotography.

A weather sealing feature is something that I wish Canon had included with the RP. The fact that this is the case indicates that I will need to exercise a higher level of care while using this camera in a challenging setting, such as when it is raining or snowing outside.

Taking everything into consideration, the Canon EOS RP is an outstanding choice for astronomical photography if you are looking for a mirrorless camera that is not only tiny but also lightweight and capable.

Canon EOS RP astrophotography settings

Astrophotography can be quite challenging because it requires a lot of manual settings. However, the Canon EOS RP is capable of capturing some amazing images if you know what you’re doing.

Transitioning from daytime to nocturnal photography necessitates particular adjustments. In my personal experience these are the optimal settings on your camera for astrophotography:

  • A proficiency in manual mode is essential for astrophotography, as all other modes are deemed unsuitable for this purpose.
  • Advantages of the RAW Format: Configure your camera to save images in RAW format. Uncompressed raw files offer a substantial amount of data and considerable flexibility for post-processing modifications.
  • Lens Fundamentals: Disable the stabilizer and autofocus functions of the lens when employing it, as they are superfluous for the purpose of astrophotography.
  • Aperture adjustment involves minimizing the lens’s wide-open position in order to prevent the star distortion that is frequently observed in the majority of lenses when set to their maximum aperture.
  • Disabling peripheral illumination correction in the settings will result in distortions that can subsequently be rectified through post-processing.
  • Caution Regarding Noise Reduction: To preserve the integrity of the image, disable extended exposure noise reduction and high-speed noise reduction.
  • Optimal ISO Selection: Configure the ISO setting in accordance with the specifications of your camera. To identify the optimal ISO for your camera, consult the user manual or the link supplied. For instance, 1600 may be the optimal ISO setting for an EOS 1100D.
  • Implementing an intervalometer in conjunction with bulb mode can effectively reduce camera motion that may occur during extended exposures.

After implementing these modifications, your DSLR is now astrophotographer-optimized. I really hope these also work for you.

How do you take a picture of the night sky on Canon EOS RP?

It’s important that you have a sturdy tripod with you when you’re capturing the night sky. Here is my simple approach to taking pictures:

  • Set the shutter speed to bulb or manual.
  • Then set the lens to its widest aperture.
  • Use ISO 1000 – 3200, and focus manually.

When you’re ready, press the shutter button You can also use a remote or cable release to open the shutter.

Currently, Canon has a few affordable and expensive wide-angle lenses for their RF mount line-up that can be used for astrophotography.

Their Canon RF 35 F/1.8 is actually a great lens for a lot of things but it suffers from “coma” when used for astrophotography.

Coma is a phenomenon that causes stars to appear as comet-like tails when they’re focused on, which is something you want to avoid while shooting the night sky.

I can also say the same with the Canon RF 16 F/2.8 STM. They both suffer from “coma.” So, that leaves us with a few options for astrophotography.
