[vsnet-chat 4932] Re: new southern variables

["Stan Walker" <astroman@voyager.co.nz>]

Hi All,

I was intrigued by the work of Vello Tabur which Fraser mentioned and took
the opportunity to look at the noted web site. It's a refreshing change to
see someone who actually follows up on new variables and gets enough
measures to enable some sort of a classification.

It's disappointing that there has been a lack of interest but not all that
surprising. Firstly, the length of time the operation has been going is
short - only a few hundred days - and Vello may tire of the game so that
after the time and trouble of setting up a database to handle all these
measures they suddenly cease! I certainly hope Vello doesn't - maybe he'll
give up comets and concentrate on variables?

I notice a comment in the database to the effect that CCD measures are much
better than visual measures. This would not go down well in certain
quarters - and is not necessarily true given the unfiltered nature of the
measures. Some observers are very good and with good sequences the results
are very impressive.

Some years ago I mentioned to Frank Bateson the probability that someone
would produce a set-up like Vello's and produce as many measures as the rest
of the section put together. The idea was derided but it seems to be
happening! Fraser mentions the NACAA meeting but a more useful spot might be
the planned AAVSO meeting in Hawaii next year? The VSS is fairly moribund at
the moment - it needed a new director years ago - and, in spite of my
aversion to American dominance of too many things, I feel that a centralised
repository for all VS measures is the best way to go.

Finally, I've been setting up a stopped down Meade 8 with BVRI filters to
measure Cepheids and Miras. But maybe the telephoto lens is the way to go.
Seems so from Vello's results.

Regards,
Stan
