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.

Day 28 Improved Pointing and Tracking, M51 with the Canon 40D and 4 inch refractor.

Following the alignment of the CGEM last night I checked the pointing and tracking of the mount which had improved considerably. I imaged M51 (single 90 second image) using the SBIG ST9XE CCD camera and the 4" Meade Refractor with the following result.

This is the FITS data about the above image


I managed to get to Telescope T11 in New Mexico today to image (300 second exposure) the same object for comparison purposes.


 My image was not too bad for a 0.1m telescope when you consider that I just took the  second image with this 0.5m telescope in New Mexico.
