About the Deep-Sky Gems

Editorial by Ian G. McGregor, February 1989

For several years now I have felt that some major changes were needed in the Newsletter. Beginning with this issue, readers will start to notice a transformation from a publication which in many resembles the Society’s Journal to a more popular level publication both in appearance and content. The story of the Newsletter should be briefly summarized for new readers.

The following corrections have been noted to the 2009 edition:

• On p. 10, the address of the Society has changed to: 203 - 4920 Dundas St W, Toronto ON M9A 1B7
• p. 23:
  • Mars ... Correction ... 282.40087 then ... 359.9484
  • The first value for the longitude at epoch for Saturn is incorrect. The correct value for 4840.5 should be 160.4377.
  • The second value for the longitude at epoch for Neptune is incorrect. The correct value for 4988.5 should be 325.4355.
