ToupTek ATR2600C AR: Sony IMX571 APS-C Cooled Color Astro Camera<\/h2>\n

Visit ToupTek ATR2600C<\/strong> (part number ATR3CMOS26000KPA V4.4) is a cooled color CMOS camera designed for
\nl\u2019deep sky astrophotography<\/strong>. Its back-illuminated Sony IMX571 sensor in APS-C format combines
\n26 million pixels, a native 16-bit analog-to-digital converter, and ultra-low readout noise.
\nIt thus offers a wide, detailed field of view, a broad dynamic range, and a simple color workflow for photography
\nnebulae, galaxies, star clusters, and large dust complexes.<\/p>\n

This version receives a Rear protective window without a built-in IR-cut filter<\/strong>. So she leaves
\nAstrophotographers can choose the appropriate external filter for each target\u2014from broadband to dual-band\u2014while benefiting from
\na two-stage TEC cooling system, an amp-glow-free design, and a 512 MB DDR3 buffer.<\/p>\n<\/header>\n

    A Sony IMX571 sensor designed for deep-sky imaging<\/h2>\n

    Wide APS-C sensor and 3.76 \u00b5m pixels<\/h3>\n

    With a diagonal of 28.3 mm, the APS-C sensor covers significantly more of the sky than a small planetary sensor, while
    \nwhile maintaining high resolution. It is suitable for eyepieces, astrographs, and corrected telescopes capable of illuminating a circle
    \nAPS-C image. The 26 MP resolution reveals the structures of extensive nebulae, the arms of galaxies, and the
    \ndense star fields, while leaving plenty of room for cropping.<\/p>\n

    Color in a Single Scan<\/h3>\n

    The color Bayer matrix enables OSC acquisition (One Shot Color<\/span>) : the information
    \nRed, green, and blue images are captured during the same exposure. Therefore, a filter wheel is not essential for

    \nor dual-band, depending on the project.<\/p>\n

    16-bit, low-noise, and high-capacity<\/h3>\n

    The 16-bit converter reproduces subtle tonal transitions and makes it easier to process high-contrast areas,
    \nfor example, around bright stars or at the center of a galaxy. The HCG, LCG, Low Noise, and High Full Well modes
    \nallow you to balance readout noise, dynamic range, and saturation capacity depending on the exposure time and the target.<\/p>\n<\/section>\n

    \n

    Controlled cooling for more consistent long exposures<\/h2>\n

    The two-stage thermoelectric module can cool the sensor to as low as 42 \u00b0C below ambient temperature during
    \nlong exposures. PID control helps maintain a stable setpoint temperature, which makes the libraries of
    \nmakes them easier to reuse and limits fluctuations in thermal noise throughout the night. The actual difference achieved
    \ndepends on the outdoor temperature, ventilation, the setpoint, and the available power.<\/p>\n

    The optical window heater, which can be adjusted to four levels, reduces the risk of condensation. The DDR3 buffer of
    \n512 MB temporarily buffers data to smooth out USB traffic and minimize frame loss.
    \nThe absence of amp-glow, on the other hand, is due to the camera's electronic design.<\/p>\n<\/section>\n

    AR Glass Version: Choose Your Filtering Options Freely<\/h2>\n

    AR stands for anti-glare<\/strong>. The window protects the sensor and minimizes reflections, but it does not include a
    \nUV\/IR cut. ToupTek specifies a transmission range of 380 to 1100 nm for AR glass; the useful response of the

    \nparticularly flexible if you use multiple types of filters and want to maintain complete control over the
    \nbandwidth.<\/p>\n
