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.

Scorpius and Jupiter

The distinctive tail of Scorpius and the planet Jupiter dominate the southern sky at 05:20 local time (03:32 Universal Time). It is fairly clear to the south there is murky cloud elsewhere but at higher altitudes parts of Lyra, Hercules, Corona Borealis and Bootes are visible. The daytime yesterday was fairly sunny in the morning but there were thunderstorms and occasional downpours during the rest of the day. 

Today I attached the ETX / canon 40D assembly to the mount and balanced the new setup.

First of all I assembled the adaptors and focal reducer, connecting the ETX to the Canon 40D

I roughly focused the setup on a distant mountain.

I now had to remove the second guidescope mount and its temporary spacers made of large washers (to allow clearance to be able to adjust the guidescope mount azimuth adjustment knob) and bolted the FLO Adaptor to the guidescope mount. I needed to slide the Primaluce bar down to allow access to the underneath of the bar to be able to insert two 1/4 inch UNC bolts to attach the FLO adaptor/ guidescope mount to the bar. I removed the 8 - inch RC OTA to make this easier. 

The image immediately below shows the guidescope mount with the spacing washers.

This image shows the second guidescope mount with the FLO adaptor in place  - matching the first guidescope mount carrying the guidescope.
