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.

John Herschel letter concerning Planetary Nebulae

John Herschel wrote this letter and mentioned a planetary nebula that he observed on 1st April 1834 from the Cape of Good Hope. He gave coordinates as shown. NPD refers to the North Polar Distance so to calculate the Declination you need to subtract 90 degrees from the NPD. So we are looking at an RA of

 NGC 9h 17m and Dec -57 degr ees 35 minutes.

This is now known as NGC 2867. In reality John Herschel really thought he had discovered a new planet as described in Steinicke's book
