With 4,144 x 2,822 pixels measuring 4.63 micrometers each, a full well of 63,700 electrons, and a quantum efficiency of over 751 TP9T, you can capture surprisingly deep deep-sky images using short exposures and stacking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In HCG mode (from gain 120), the readout noise drops below 2 electrons, making exposures of 30 to 60 seconds yield usable signals even without a cooled sensor.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-2600-MM-Pro-Mono.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-6.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-5.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-4.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-3.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n<\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-6.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">Mobile and immediately deployable<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Without a heat sink, the camera weighs very little and operates on a single USB cable: ideal for travel setups, short sessions, and anyone who wants to keep the entry into serious deep-sky photography accessible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 4\/3 image field (23.2 mm diagonal) captures complete nebula fields and pairs well with apochromats and corrected Newtonians.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/ZWO-Camera-ASI-294-MC-Color-5.jpg\" alt=\"ZWO ASI294MC color camera with 4\/3 inch Sony IMX294 sensor\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">Also for the moon and live observing<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With 16 frames per second at full resolution, lunar overviews and electronically assisted astronomy (live stacking) are well possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those who later progress to long exposures choose the Pro version with TEC cooling;
