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.

« The Moon - 15th April 2019 | Main | HIP 42497 OCCULTATION BY THE MOON - animation »

Occultation of M44 stars Tycho 1395:1993 and tycho 1395:2711 - animation

On Saturday 13th April 2019 the Moon moved across the Open Cluster Messier 44. The animation below shows the Moon  occulting two of the M44 stars as it moves from West to East. The exposure time for each image was 0.05 seconds or 1/20th second. The time each 0.05s exposure started is shown at the bottom of the screen.  There is roughly 7 seconds between each exposure. The two close stars pop out of view behind the Moon in sequential frames. An earlier (single) occultation is shown in the previous posting.
