![]() ![]() Plate solving gets its name from the time of early astrophotography, when camera images were taken on photographic plates that were covered with an emulsion to engrave the image to the plate. ![]() Get data from top-notch professional telescopes located under the world’s best night skies without leaving the comfort of your home. It does this by taking an image of the sky where you are pointed to, compares the stars in this image to a reference catalog of the sky to know with a high degree of accuracy where the mount is actually pointing and then calculates the corrections needed to move the mount to center on the astrometric coordinates you defined as the target. ![]() The result is that SGP uses this information to make corrections to where your telescope is actually pointing (via your mount) so that in the end, your telescope is pointing at the target you want it to and not elsewhere. Usually the object you’re solving for is the target object in the image. This sounds like a good time to review what this tool is and why its useful to have. Plate solving, which I think is more formally called Astrometric solving is a technique used to calculate the celestial coordinates (RA and Dec) of any object in an image. However, now I’m having to wrestle a bit to get plate solving to work as advertised. For the most part, it’s been a fairly straightforward journey. I’ve spent the last few months working to get proficient using Sequence Generator Pro (SGP). ![]()
