[vsnet-chat 6127] Re Nova Search



Hello All,

Between time demands of work, family and the occasional clear night I am
struggling to keep up with the discussion on nova search and LPVs.

I also continue a regular visual nova search in several areas along the the
southern Milky Way in Vela, Crux/Centaurus and Scorpius/Sagittarius.  This
is done with hand held 10x50mm binoculars to a limiting magnitude near 8
with the aim of recognising any novae present to magnitude 7 or brighter. 
This search is usually followed by (or preceeded by) a quick naked eye
search along the Milky Way to magnitude 3 or 4.

My nova search usually represents the final stages of dark adaption before
moving onto the binocular variables.  To date, there have been no novae to
these limits discovered in these fields on the nights I have observed and
therefore missed.  There are also one or two nights when I SHOULD have
observed......  Hmmm.

Not surprisingly, the binocular search areas seem to connect a number of
fields surrounding binocular and telescopic variables on my regular working
list.  Each of my 30+ binocular variables near the plane of the galaxy also
double as nova search fields as I feel an object of magnitude 6 or brighter
would be quite obvious to the alert observer, depending upon its location
with respect to the variable and comparisons under observation.

This can be extended further to include the wider low magnification
telescopic fields when star hopping between nearby variables.  A number of
asteroids have been reported through the vsnet in this manner.  And who
knows, it may even be possible to discover a comet in this way!!

Without doubt, photography is far more efficient than visual but this
should not deter the visual searcher.  It is all a matter of timing and
recognision.  The sky is there to enjoy and if we are not looking at all,
we will miss everything!
