This is an announcement of an updated version (1.3) of my quick-and-dirty,
Python-based telescope archive search tool, available here:
(A short summary of what it does is appended below.)

New features (and fixes):

- Updated to work with DR6 of SDSS.

- Restored access to the older version of the Isaac Newton Group Archive.

- The package now includes a separate script called "fetchsdss", which allows
for command-line retrieval of FITS (or JPEG) images from the SDSS archive
via object name, coordinates, or SDSS field specification.

[previous summary, updated:]
"Telarchive" is a command-line program which simplifies searching various
public telescope archives to see if they might have data on a particular
astronomical object or part of the sky.  This includes the HST and general
MAST archive, as well as the ESO, UKIRT, CFHT, and AAT ground-based
archives, and imaging data from Data Release 6 (DR6) of the Sloan Digital
Sky Survey.  The NOAO Science Archive is also included, though it has very
little publically available data at this point.  Recent additions are SMOKA
(the archive for Subaru and several older Japanese telescopes) and the
Gemini Science Archive.  The Isaac Newton Group Archive is also searched,
but only for data from 2001 or earlier (newer data is handled by the new
archive interface, which is currently not usable by this program).

The program won't *get* the data for you, of course (but see "fetchsdss"
for SDSS images), or even tell you very much about it -- for that, you
still need to visit the individual archive web pages.  But it will save you
lots of clicking and typing in web-page forms if you just want to find out
if there is *any* data available.

An example (searching within a 2-arcminute box centered on the planetary
nebula NGC 7027; searching on coordinates directly is also possible):

$ telarchive "ngc 7027" 2.0
         SIMBAD (Simbad 4, France):  Found object coordinates: RA = 21 
07 01.593, Dec = +42 14 10.18

Searching archives for ngc 7027 (RA = 21 07 01.593, dec = +42 14 10.18),
with search box =  2.0 arcmin...
