Product Details

  • The ASI174 Mini is a top-notch monochrome guide camera, well suited for both planetary imaging and acting as a guider to amplify the usefulness of other astronomy instruments. Despite being qualified as a 'miniature' camera, it still operates at a high level of performance; with a peak QE of 77%, a read noise of only 3.5e, a pixel array of 1936 x 1216, and a pixel size of only 5.86 microns, it qualifies as a powerhouse despite its small size. It achieves all of this while presenting a small and slender profile, taking up a minimum of space in your imaging train.

    Great Guide Camera for Long Focal Lengths

    At 2030mm I was able to find guide stars. I was in a hurry, so I didn't take the time tweak the settings. I did create a dark library, though. I only cranked the gain and binned 2x2 in PHD software. It got me through the night. The only issue was with the ZWO OAG, not the camera. The camera has a very wide FOV, but the prism on the OAG, not so much. With the ZWO OAG you get a small circle to locate your guide stars. But thanks to the sensitivity of the camera, you find guide stars easily.
