Searching for 3434 Hurless: The Photograph
20 minutes, 5-inch F6 A-P refractor, Lumicon minus-violet filter,
on hypered Kodak 2415 Technical Pan film developed 8 minutes in D-19
at 21C. Autoguided on a Losmandy G-11 mount using an SBIG ST4 CCD
behind an 80mm Orion Short Tube Refractor.
This image of 3434 Hurless was made on October 17-18, 1998, around
22:15 EDT. It's a small portion of the original negative and is shown
at a scale similar to Paul's drawing and to the Digitized Sky Survey
images elsewhere on this website. The limiting magnitude is
near 17; the brightest stars in the frame are 9th and 10th
magnitude. The scale of the image is just sufficient to show the 10
arcsecond trail of the asteroid during the .33 hour exposure. This
is the latest in a long series of attempts to photograph 3434 Hurless
at successive oppositions. I'll post more when time permits.
This one is special because it confirms our visual observation of
the difficult object.
While we poured over the 16-inch's eyepiece, I forgot that I had
left the shutter open behind the refractor. I meant to make a
20 minute exposure of the Pleiades. Instead, I made a 90 minute
exposure. It's badly skyfogged, but I did my best to save it.
I added color in Photoshop.
