My "Supernova Predictors"

Hello all,

I have a confession to make: I have this bad habit of working on an image, then giving up after a while because I'm not happy with it with the intent of coming back "some day" to work on it. I then either never get around to it, or go back, fiddle with it a bit, then forget about it.

I resisted this urge with my recent sharing of the two faint objects, specifically the Sharpless 183 image. That one was, I felt, not ready for prime time, but I shared it anyway, warts and all. The feedback was enough impetus to make me look at the image with a fresh eye. I am currently working on a bit of a redo on that target. Expect a reshare of that nebula soon.

With that philosophy, please allow me to share two images going back a couple of years (yes, years!). I call this pair my "Supernova Predictors", because in both cases, a supernova went off a few months *after* I shot a galaxy in that composition!

The first is M101, a nice big galaxy near the Big Dipper. This is quite aptly called the Pinwheel Galaxy, though I will admit that I am a bit confused by that moniker, as M33 (http://www.skiesbyafrica.com/Galaxies/M33.html) is also called that:

Next is a wide field of galaxies in Leo that I originally planned to call "The Trio in Leo 2", as a nod to the original Trio in Leo (http://www.skiesbyafrica.com/Galaxies/TrioInLeo.html). There are more than three bright galaxies in this field of view, however, so I decided to call it a "Quintet in Leo" instead:

As mentioned in the text of this page, quite a few asteroids zipped through the field of view as I shot this area:

Enjoy,
Eric

Wow Eric...

I don't think I have ever seen so many asteroids in one image. I counted at least 15 and they showed a lot of movement during the exposures. When was the image taken? You are a one man NEO survey. (o:

Very cool Eric!! The asteroid count is amazing! I'm hoping you and your fellow club members have put out a 2013 Astro calender as Teri and I thoroughly enjoyed the 2012 version that you and Josephine so graciously gave me at last years NEAF. smile
