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.

More Galaxies

It was really clear at first last night with no Moon - stars everywhere! I started a galaxy run starting at RA 4h with the sidereal time being about 2h - I now sychronise on a bright star near the beginning of a run and then map 6 stars nearby. This gives me sufficient pointing accuracy to get the scripted galaxies onto the field of view. I realised after a while that images were reducing in quality and went out to find cloud moving in. I managed to image 96 galaxies before the cloud cover became total and checked all of these for supernovae - none there. As the galaxy run was taking place I was trying to set up my Canon DSLR with the CGEM mount and Meade 4" refractor - using remote software to take 30s images of the Orion Nebula region. Clearly my polar alignment was not good so that needs to be resolved. Next opportunity I am going to try some software that allows me to use the DSLR for polar alignment to save having to swap back and forth with an illuminated reticle eyepiece that I normally use.
