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