About the Site

 I try to log my observing and related activities in a regular blog - sometimes there will be a delay but I usually catch up. An index of all my blogs is on the main menu at the top of the page with daily, weekly or monthly views. My Twitter feed is below. I am also interested in photograping wildlife when I can and there is a menu option above to look at some of my images. I try to keep the news feeds from relevant astronomical sources up to date and you will need to scroll down to find these.

The Celestron 14 is mounted on a Paramount ME that I have been using for about 10 years now - you can see that it is mounted on a tripod so is a portable set up. I still manage to transport it on my own and set it all up even though I have just turned 70! It will run for hours centering galaxies in the 12 minute field even when tripod mounted.

The Minor Planet Juno

Discovery

From the Lancaster Gazette of 11th May 1805

ASTRONOMY. Another new planet has been discovered by M. Harding, of Lilienthal, near Bremen, to which he has given the name of Juno. It is of the eighth magnitude, and attracted his attention while comparing with the heavens the 50,000 stars observed by Messrs. Lalande. It appeared to have a peculiar motion, and after observing it for several days, he clearly ascertained that it was a planet. Its right ascension on the 5th of September was 1° 52, its north declination 0° 11. The same planet was observed by M. Burckhardt, on the 23d of Sept. at 3-9* 7 4° 6, from which he inferred that the dura- tion of its revolution is five years and a half. The following particulars have also been ascertained : its inclination is 21". Its eccentricity is a quarter of its radius. Its mean distance from the sun is three times that of the earth, or about 100 millions of leagues ; it is consequently farther than Ceres, or Pallas, whose distance is 96,000,000. Its diameter has not yet been ascertained ; but its size appears nearly tbe same as that of Ceres, or the planet discovered by Piazzi. This is the twelfth planet discovered within a few years, Herschell having discovered Uranus and its six satellites, and two new satellites to Saturn : Piazzi discovered Ceres, and Olbers discovered Pallas. M. Piazzi, the celebrated Astronomer of Palermo, has ascertained a change on the fixed stars of one, two, and three seconds, on account of the situation of the earth in its orbit. This effect of the annual parallax, concerning which disputes have existed for more than a century, is considered of great interest to men of science.
