BPM 37093 (a.k.a. L 327-186) Finder Charts

For each chart, you can either display a larger JPEG image, or download a gzipped PostScript file.

A Note on Proper Motion: BPM 37093 has a proper motion of:


d(RA)/dt = -0.0573 s/yr = -0.86 arcsec/yr
d(Dec)/dt = -0.130 arcsec/yr

The images below are from the Second All-Sky Survey, which took place in the 1980s. Thus they are approximately 10-20 years old, and the star will have moved 10-20 arcseconds west and 1.5-3 arcseconds south with respect to its position in the finder charts. You may want to note this on your hard copies of the finder chart.

The circles represent the approximate area vignetted by the central hole in a Texas-style photometer for telescopes with plate scales of 10 arcsec/mm (small circle) and 20 arcsec/mm (large circle).

The stars marked (1) and (2) are the suggested comparison stars.
