My primary compassion in astronomy is observing and imaging supernovae. From 2010 to 2015 I was the primary searcher for supernovae through CRTS SNHunt nesssi.cacr.caltech.edu/catalina/current.html. Drake, A.J. et al. First Results from the Catalina Real-time Transient Survey, 2009, ApJ, 696, 870. During that time, I discovered or co-discovered 119 supernovae that were confirmed with a spectrum, over 120 other transients which were probable supernovae though a few may have been supernova imposters, and three confirmed supernova imposters . Additionally, a number of variable stars within our Milky Way were discovered.

Due to security issues, my first flickr account which I had from 2007 to 2016 and was a pro account had to be deleted. This, unfortunately, created a number of dead links from astronomy sites and publications that pointed to my images. The website most affected is David Bishop's supernova site www.rochesterastronomy.org/snimages/.

I created a new account to accommodate my images and have not uploaded all that were once on the previous account. In late 2023 into 2024 I reloaded a number of images of supernovae though not every one imaged or if there were multiple images of a supernova were loaded.

In general, unless otherwise specified, I try to oriented astronomical images that were taken through telescopes with North up and East to the left.

CBAT list of supernovae prior to 2016 www.cbat.eps.harvard.edu/lists/Supernovae.html

CBAT TOCP from 2011 to present www.cbat.eps.harvard.edu/unconf/tocp.html From 2011 through 2016 this was where supernovae suspects were to be posted. Once confirmed as a supernova it would be moved to the CBAT list of supernovae. There are objects on this list that were most likely supernovae, including a number of my discoveries through CRTS SNHunt. After 2016, most objects listed are likely Milky Way variables, though some are external galaxy novae.

Transient Name Server (TNS) is the current location for reporting supernovae suspects: www.wis-tns.org/
