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.

CGEM Pointing Test

It was clear last night with occasional drifting cloud but I managed to successfully get the CGEM to follow an Orchestrate script and take images (albeit only 1 second images) of galaxies. The CGEM managed to centre these very well although all the galaxies were within a few degrees of each other. The process is more complex then using a Paramount in that I really need to go through a process of alignment each session simply to get to the point where I can synch The Sky to the telescope. Once The Sky is able to recognise where the telescope is pointing I can do a plate solution and synch on the centre of the solved image.  This normally requires at least a 10 second image or more to get enough stars for The Sky and CCDSoft  to compare with the chart.
