After learning about the SN in M82 I went back and looked at images I've taken of M82 over the past several days. I did not see the SN in the normally processed images owing to its being buried so near the core of the galaxy. But by stretching the histogram of each image I saw the SN going back several days from the 16th to last night. Download GIFs of the images here: http://users.wirelessbeehive.com/~paw/temp/m82_14-22.zip Note that these are GIFs of raw images. No darks or flats applied. I guess I have to count this as the one that got away. :) I'm also thinking I should start using shorter exposures. When I get some times I'll see about "prettying" them up and putting them into an animation. patrick

Patrick, don't be a hog. You already got one. Leave some for us.

But Joe, they're like the commercial used to say about potato chips: Ya' can't have just one. :) But seriously, a number of the galaxies I check are bright like M82 and I've oft times wondered if I'd miss one in or near the core. Now I have my answer. So next clear night I'm going to experiment with shorter exposures on the brighter galaxies. patrick On 22 Jan 2014, at 21:47, Joe Bauman <josephmbauman@yahoo.com> wrote:

The animation looks great Patrick! Can you get any kind of light curve data off of those? As a photographer that shoot HDR images most of the time I'm all about bracketing the exposure whenever I shoot "just in case" Seems like that would be a good practice for bright core galaxies, of course I shoot for aesthetics not data.

Thanks Howard, I don't think any light curve I got from those images would be any good considering how much I had to stretch them to bring out the SN. patrick On 23 Jan 2014, at 00:39, Howard <sumoetx@gmail.com> wrote:
