centered on a central star of mag10, round and quite homogeneous with a
very slightly brighter area crossing the object from WNW to ESE (brightest

and 9'S.

I can provide a scanned drawing of NGC 1514 to anyone who can read the
binhex encoding of Eudora (for Mac); just mail me to try
(ypothier@abi.snv.jussieu.fr), it works quite often with other
configurations...
