Shapely was involved in a great debate about the nature of spiral nebulae (faint patches of light visible in the night sky). He believed that they were "island universes," or galaxies outside the Milky Way. Another astronomer, Heber Curtis, believed that spiral nebulae were part of the Milk...
By far most of the baryonic matter is found in loose nebulae. But still, that's nothing to sneeze at, and it means that black holes are frighteningly common. Follow us on Twitter @Spacedotcom or on Facebook. Join our Space Forums to keep talking space on the latest missions, night...
like theHubble Space Telescope, Pagan said. But even that comparison isn't quite right, since Hubble is much bigger and more sensitive than the human eye. Also, visual-light telescopes might capture different features of an image than an infrared telescope...
During the first weeks, I always dreamed to do some nebulae, but I wasn't able successfully to get any reasonable result. Until September 2021, I added a filter to my setup and here it is,M52 What are my goals? Middle of November I targeted onCrescent Nebula | NGC6888 | C27by watchi...
There are a few PNs also, but they are high magnification objects. For DSOs you will need filters for Nebulae of both types. For all other objects, you will need a good set of EPs, or a few EPs and a good Barlow or 2. Finally, just forget seeing anything looking like an astrophoto...
