Pro-Am Astronomy 19th century style

 

Weekly Advertiser Sunday 22nd October 1865

Amateur astronomers of Great Britain and Ireland are invited to send to the President of the Royal Astronomical Society, Somerset House, a short account of their means of observation : for example, the nature of the instruments they possess stating (in the case of telescopes) whether they are refractors or reflectors, their aperture, focal length, and form of mounting; also, whether the instruments are placed in observatories or used in the open air.
