This view provides a helpful list of cameras with differently sized image sensors, telescopes, and Barlow lens options to overlay a helpful frame guide showing exactly what you’ll be capturing when shooting. For the average stargazer, ocular view provides more than enough information and scalability, but astrophotographers might consider the image sensor frame view. Namely, ocular view, image sensor frame, and Telrad sight. One option we particularly love is the ability to switch between different view modes. To view every deep-sky object on the software, you’d have to sift through the 80,000 different options available, which increases to over a million with the additional catalog. It contains a huge catalogue of over 600,000 stars added to by additional catalogs for more than 177 million. It’s easy to see why Stellarium is much-loved among amateur astronomers and stargazers across the globe.
