It is the pixel pitch that will determine the image scale and resolution. CCD Planetary Critical Sampling. Astrophotography and CCD Calculator Features. It related to two parameters within the imaging system . What is the image scale of the KAF-1301E CCD (arcsec/pixel)? More reference images for CCDCalc! Scaling percentage 3. Pixel size of the camera (in my case 3.69 microns) The focal length of the telescope (in my case 1600mm) Irrespective of the image scale your system can achieve, it is limited by two factors working against this figure It requires that you take a test exposure using your CCD imaging setup and measure the background sky value. Using the image size calculator is easy: 1. Help us to grow by adding additional equipment to the database. Click here to download the full version of the CCD Calculator program (3.3MB). CALCULATOR FOR MAGNITUDE LIMITS FOR CCD & TELESCOPE - L. Bogan VERY VERY EXTENSIVE. <= note these are inches! CCD Filter Size Calculator. Planetary section with sampling rate, required barlow, video times for planets. The display size is also considerably larger in the second image due to the larger camera’s greater number of pixels. This calculator is very useful for choosing just the right size to scale your image to. Basic parameters such as FOV, resolution, airy disk, image scale, etc. It is the pixel size itself that matters and of course the resolution of the Telescope. Focal Length: mm. The BBC has launched a new app that shows how your body weight ranks against people globally. Telescope: Aperture: mm. That looks about right, but why does the inter pixel gap matter? This calculator allows you to determine the ideal exposure time for subframes that will be stacked. Barlow / Reducer: Filter to CCD Distance: mm. This is based on the assumption of perfect seeing and the Airy disk being the limit of resolution. Deep Sky section with sampling rate based on seeing, required barlow, etc. One pixel is 16 microns, so this corresponds to an image scale of Add New Equipment To Database. Vignetting and field of view, coma, focal depth, thermal shift of focus. Ideal Exposure Calculator. Future height or width. The focal length is f = (f ratio)D = 10*10 in = 100 in. Camera: CCD Diagonal. In all version since Version 1.2, you can create your own telescope and camera entries. Often referred to as image scale, it is measured in arc seconds per pixel. CCDCalc is now a free program for anyone; you do not need to buy the book. Telescope A: 400mm focal length Putting in 8.6x8.3 as the pixel pitch and 752x582 as the resolution, gives a resolution of 1.48aspp horizontally and 1.43aspp vertically. Will give you the same pixels per star with all other things being equal. mm = Recommended Minimum Filter Size: mm × Close Add Equipment To The Astronomy.tools Database. We asked people to test it and this is what they told us. How to Use the Image Size Calculator. The size of the CCD will usually not matter in regards to over or under sampling. Use this formula to calculate the minimum focal length required to fully sample a high resolution image with any particular CCD. In this case, a large CCD with a long-focal-length scope gives the same field as a small CCD on a short-focal-length scope, but the image scale is greater on the larger instrument. | Cookie Policy | Privacy Policy | Terms and Conditions | Acknowledgements | Bug Reports | Get In Touch | First Light Optics Ltd All rights reserved © 2020 This calculator allows you to enter the following components: 1. Magnitude Limit of CCD Camera and Telescope Calculator "...determines the response of a telescope and CCD camera to given stars and seeing conditions..." Magnitude Limit of CCD Camera and Telescope Calculator INPUT Values include: The plate scale is s = 0.01745 f = 1.75 inches/degree. Original height and width 2. For example a CCD with 9x9 micron that is very large vs a ccd that is 9x9 micros that is very small.
