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.

More images from supernova ASASSN-14jg(taken 2 hours ago).

I just received three images of the supernova from T31 in Siding Spring Australia. They should have been sent directly to VPhot at the AAVSO but they have not appeared in the image list yet. I downloaded one myself directly ASASSN-14jg 300 second V filtered imageand tried to upload this into Vphot. Although it seems to have uploaded successfully for some reason it has not appeared in the image list. There must be some sort of issue there.

From the 300 second imageI want to get a V magnitude for the supernova based on a lighter image with lower ADUs further from saturation. For that reason I took 60s, 180s and 300s exposures and will choose the most appropriate. I will then take images every day to be able to plot the light curve.

The image on the left is the longest exposure of 300 seconds.The supernova is still bright and equals the SN in M61 which is getting all the press.
