Mati's object is a galaxy, CGMW 4-6831, according to SIMBAD. The object is one of about 100 found in a search by Roman et al., and published in 1998 in the PASJ. The catalogue is available on-line from the data-centers. Here is the biblio citation from SIMBAD: 1998PASJ...50...37R: ROMAN A.T., NAKANISHI K., and SAITO M. <Publ. Astron. Soc. Jap., 50, 37-46 (1998)> A systematic search for galaxies behind the Milky Way at Sagittarius. Notes: Available at CDS: <CDS Catalogue: VII/209> Dictionary: <CGMW 4-NNNN> (Nos 4-1 to 4-7154) (here table 2: N=107) The galaxy is classified as an elliptical in this paper, with dimensions 0'.4x0'.2. I note also that the GSC-ACT position is: 19 18 05.20 -23 50 02.2, and that the GSC classes this as stellar. The "best" position is probably an average of USNO-A2.0 and GSC-ACT. \Brian
