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.

A study of the star cluster NGC 6716 Part 1

DateThursday, October 9, 2014 at 11:54AM

NGC 6716 is a star cluster in Sagittarius consisting of young stars.

I took a number of images on 13th September 2014 using the T17 telescope at Siding Spring in New South Wales, Australia with a view to analysis using BV photometry so that I could find more about the cluster stars and the cluster itself.

Just how much is it possible to find out from two of these monochrome images?

 

This telescope holds the world record for imaging the faintest object ever imaged by an amateur - a quasi stellar object whose light started its journey 12.79 billion years ago!

Here is the telescope data courtesy of itelescope.com

Here are my 3 minute V and B images. Note that North is down and East is to the right in all of these images.

 

This is the 300second B image in VPhot. Two variables have been identified in the image on the right hand side.

 

 To be continued.....
