Project: constellation or star trails without a telescope

Tier: 2

Location: ahso

Other information, requirements, or equipment you must supply (may be blank): requires a camera with a manual exposure setting

Take a picture of a constellation or star trails without a telescope. You will probably want to take several different exposures of the same thing to determine the best exposure and aperture. Note this requires a camera with manual exposure setting (generally an SLR). Some of the C8s at Angell Hall have "piggyback" mounts for cameras so they can track a constellation without looking through the telescope for long exposures, though a tripod is sufficient for most images. Make sure you record all the image data like the camera make & model, lens (for a camera with interchangeable lenses), exposure, aperture, f-stop, telescope information (if using a telescope), or anything else you need to know to repeat the image. Most modern digital cameras record this data in the image metadata, which you can access in software like Photoshop and Gimp, or some photography sites like Flickr. For the image of the constellation, http://nova.astrometry.net/ can help you identify the constellation. For star trails, identify 2 - 3 of the stars in the field. Turn in your image (a digital copy is acceptable), a copy of your image with the constellation or stars identified, and a document showing the image data.
