NGC 2841
NGC 2841 is an inclined, unbarred spiral galaxy exhibiting a prominent inner ring structure in the constellation Ursa Major. It was discovered on 9 March 1788 by William Herschel. Initially thought to be about 30 million light years distant, a 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined that it was approximately 14.1 megaparsecs or 46 million light years distant.

NGC 2500
NGC 2500 is a barred spiral galaxy in the constellation Lynx which was discovered by William Herschel in 1788. Much like the local group in which our own Milky Way galaxy is situated, NGC 2500 is part of NGC 2841 group of galaxies which also includes NGC 2541, NGC 2537 and NGC 2552. It has a H II nucleus and exhibits a weak inner ring structure.
