10MP - APS-C CMOS Sensor ISO 100 - 1600 ( expands to 3200) Canon EF/EF-S Mount 3.00" Fixed Type Screen Optical (pentaprism) viewfinder 6.5fps continuous shooting No Video Mode 822g. 146 x 108 x 74 mm Weather-sealed Body Canon EOS 40D Astro Modified is a modified version of the Canon EOS 40D DSLR camera, specifically adapted for astrophotography. This modification involves removing the IR (infrared) filter from the camera's sensor, allowing it to capture clearer and more precise images of the night sky and other cosmic objects. Here are some features and advantages of a DSLR camera modified for astrophotography: Modified sensor: Removing the IR filter allows the camera to capture the red light from cosmic objects more efficiently, such as emission nebulae and other astrophotographic phenomena. Low-light sensitivity: Cameras modified for astrophotography are more sensitive to low-light conditions, making them ideal for capturing details in low-light situations or during astronomical observations. Manual control: Canon EOS 40D Astro Modified offers extended manual control over settings such as exposure time, ISO, and white balance, which is essential in astrophotography to achieve high-quality images. Compatibility with astronomical accessories: This camera can be used with various astronomical accessories such as telescopes and equatorial mounts to capture long-exposure photos of the night sky and other cosmic objects. It's important to note that astrophotography typically involves using specialized equipment and advanced technical knowledge to achieve desired results. If you're interested in astrophotography or want to expand your activities in this field, a DSLR camera modified for astrophotography like the Canon EOS 40D Astro Modified can be an excellent option to start with. The modified camera for astrophotography can also be used in normal shooting conditions by manually adjusting the settings. Although the sensor sensitivity is increased and optimized for capturing infrared light and other wavelengths specific to astrophotography, it doesn't mean that it cannot be used for other types of photography. By manually setting the parameters such as ISO, exposure time, and aperture, you can adjust the camera to match the lighting conditions of the environment you are shooting in. In fact, the advantage of a camera modified for astrophotography is that it can offer higher sensitivity in low-light conditions, which can be beneficial in night photography or indoor low-light situations. For example, you can use the for capturing nightscapes, capturing details in low-light conditions, or experimenting with artistic photography in less conventional environments. However, it's important to understand that the increased sensor sensitivity can also affect aspects such as digital noise, especially at higher ISO settings, so you should adjust the settings accordingly to achieve quality results. In conclusion can be used in various ways, including for photography in normal conditions, through manual adjustment of settings. It is a versatile camera with extended capabilities due to its modification for astrophotography, allowing you to experiment and capture unique images in a variety of photographic scenarios In the presentation images, you have at the end of the presentation a few shots taken directly with this camera, and of course, the sensor integrity test.
