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.

Comet C/2017 O1 (ASASSN)

Within the constellation of Camelopardalis I know that Comet C/2017 O1 (ASASSN) is visible with a predicted magnitude of about 12, with an azimuth position of 30° 38' 36".  As I have still not set up my equipment, I linked my laptop to a telescope in Nerpio which is 189 km away by road from my location in Mojacar - slightly west of North - and took an image of the comet. The image is a 10 minute exposure. The position of the comet was RA (2000) 04h 52m 56s and Dec (2000) +65° 14' 45". The altitude of the comet was +49° 58' 31". As a comparison the star UCAC4 777:18393 has a magnitude of 11.26. The exposure started at 23:11:53 Universal Time on 27th October 2017. (01:11:53 on 28th October 2017 Local Time in Spain.)
