Negatives - October 1998 1998 |
M74 is a large face-on spiral galaxy located in the
constellation Pisces. It shines at magnitude 10.2 and is a suitable
challenge as a photographic object in smaller telescopes. The asteroid
Pierretta (312) shone at Magnitude 13.0 at the time it was caught
crossing my intended photographic object, M74. It was common for the
early asteroids to be named and also their initial cataloging reference
discovery was common for those that crossed brighter Galaxy objects,
since those Galaxies were the targets of Supernova searches, and
underwent constant monitoring, my hopes for a new discovery were short
lived, as a quick cross check thru the minor planet center showed this
asteroid due thru the region.

Processing Info:
The above reprocessing was done to add the representative chart as a
mouse over. The only significant question remaining at this point is if
the emphemerius is off for this object, as pre-programmed into Megastar.
The delta path to my pictures is significant.
