Object Name: Leo II and Copeland’s Septet

Object Type (Galaxies)
Location (Nienawiszcz, Poland)
Date (05-may-2014)
Equipment: Newtonian telescope 409/1800 (Capella 41), WO SWAN 40mm, ES 14mm eyepiece , Soligor Barlow 2X
Object: – Artist: Robert Twarogal (Ignisdei)

Night from Saturday to Sunday (3-4 May 2014) was beautiful. The observation started at 22.00. Near the Star „Gamma Leo” I found a spectacular Leo II (dwarf spheroidal galaxy UGC 6253 ( distance from Earth of 750 thousand light-years.) Galaxy Leo II was discovered in 1950 by Robert Harrington and Albert Wilson under the Palomar Observatory Sky Survey. Leo II belong to the our Local Group, and is a satellite of the Milky Way. Beautiful large, galaxy, „rather” visible in 41cm mirror + Swan 40mm and Soligor Barlow 2X

Then with some dose of skepticism I began to search a Copeland’s Septet (Hickson 57)

This is a close gropup of seven galaxies that lies about 480 million light-years away in Leo, discovered by Ralph Copeland in 1874. An apparent magnitudes of them: between 13.6 and 15.2, it was hard to divide, They are very faint even in Newtonian 16” + ES 14 mm in power 128X.

One of the most popular “challenge objects”. If you want to observe this objects, one thing is very necessary – clear dark sky. Why? This objects are vey faint so good contrast between galaxies and sky is the most important thing. After few minutes of eye adaptation you can observe four very faint galaxies on the longest side of triangle of three bright stars (it is quite easy to find because it is near very bright galaxy NGC 7331). Very interesting objects – you must have it on your observation list under really dark sky.
