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.

Wednesday 14th May 2014 - One Second Image of M13

Globular Cluster M13 - 1 second exposure.
On Friday May 14th 2010 I was still using the 12" Meade as my main instrument and was focusing the telescope on M13 using 1 second exposures and realised how much detail was captured in that brief time. M13 was high in the Sky (Airmass 1.064 - 70 degrees altitude) which makes a huge difference in Leyland due to light pollution nearer the horizon - as well as having less atmosphere in the way). I decided to save this raw image (ie no image enhancement or processing) just as a record of what can be captured in 1 second with a 12" OTA and SBIG camera at -5 degrees C..
