Astronomy Blog Index
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.

Rain and Cloud today

No astronomy possible tonight. I earlier checked the operation of the roof of the observatory during a dry spell - it works fine. Also I needed an appropriate sized adaptor to connect my ETX90  OTA to my Canon 40D. I bought this adaptor last week and connected it to the ETX today.

Baader Planetarium 7 mm Ultra Short T-Adaptor 

 

Together with my Meade f/6.3 focal reducer this will allow the full moon to fit into the field of view. 

Product Description

SCT adaptor Ultras nursery, T2 (Male)/2SC (female). Only 10 mm Optical length. Specifications: Weight (kg): 0.038. Optical tube length: 7. Inner Diameter / Clear Aperture (mm): 39. Outer Diameter: 56. Inner Connection (lens sided): Thread, 2". Outer Connection (eyepiece/-camera-sided): Thread, T-2 (M42 x 0,75). Compatible Brands: Astro T-2, UNC, Baader Planetarium, Celestron, Other. Type of Adapter: Reducing piece

 

I also ordered an adaptor for the Guidecope mount that I use to hold the Canon 40D/ETX. At present I have a stack of washers but need a more solid way of attaching the mount to the Primaluce bar. This is the same adaptor that supports the guidescope mount for my SkyWatcher 80mm guidescope.
