The Nature Hike, however, is recommended for ages 12 and above. Almost everyone can see the Sun (safely) through the Solar Scope. Grade school kids will know a lot about the Solar System and will appreciate the scale of the Orrery. Even very young kids can enjoy hopping along the stepping stones of the planets' orbits in the Orrery and can appreciate hearing about cactus and desert plants on the Nature Trail. The default settings do a histogram equalization and produce a gray image from which it is very difficult to regain color without enhancing noise. Saturday mornings at STL are great for all ages. Deep Sky Stacker, DSS, is a free program that does an excellent job of aligning in most cases, and can stack with sigma-clipped average. If kids are of an age that they are learning about the planets and constellations, the night viewing session will be meaningful. Plus, the campus is kept very dark for optimal viewing, and young kids can get bored with the slow pace of the evening. Even if the child can be trusted to keep hands behind their back, it is still difficult to find the object and get it in focus. Their natural tendency is to grab the scope or the eyepiece, which, of course, throws it out of alignment and can take a few minutes to bring back around. The Microsoft Windows file extension for this data format is '.dds'.Īpple Safari, Google Chrome, Mozilla Firefox, Internet Explorer, Adobe Photoshop, Paint Shop Pro, the GIMP, ImageMagick, IrfanView, Pixel image editor, Paint.NET, Xara Photo & Graphic Designer.A: Of course, it depends on the maturity of your child, but our experience is that kids younger than 6 have a very hard time looking through a telescope. The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. Click icon to show file QR code or save file to cloud storage services such as Google Drive or Dropbox. The output files will be listed in the "Conversion Results" section. It will automatically retry conversion on another server if one fails, please be patient while converting. Click the "Convert Now!" button to start batch conversion. The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM, SVG, etc.ģ. If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). The image quality option only works on a few image formats such as JPG, WEBP or AVIF. You can use the original image size or select the "Change width and height" option and enter a custom image size. Set target image format, image quality and image size. With iObserve you can add your own topic requirements/objectives and time stamp them to the recording. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.Ģ. Click the "Choose Files" button to select multiple files on your computer or click the dropdown button to choose an online file from URL, Google Drive or Dropbox.
