Sancho’s objectSancho’s object  (15 10 17.6  +58 10 38   size 0.6x0.2’   mag 16.5)

22” at 306, 383 and 460x – This object consists of two very close interacting neighbors.  MAC 1510+5810 is a considerably bright 3:1 elongated glow.  PA = 150 and 0.3’ long.   MAC 1510+5810A is a considerably bright round glow with high surface brightness.  They are separated at 383 and 460x at about 15” apart.  A bright mag 12.0 star lies 0.6’ due west of the pair.  This pair appears brighter than the listed magnitude, closer to 15.0.   This object was independently discovered during the Megastar astronomy catalog upgrade.  It was named after Jose and Susan Sancho of Texas, who are among the finest visual observers.

 


NGC 5777NGC 5777  (14 51 18.0  +58 58 37   size 3.1x0.4’   mag 14.1p)

22” at 184, 230, 306 and 383x – Considerably bright ghostly glow, even surface brightness with diffuse edges.  PA = 60 and 1.8’ long.  Nearby galaxy, CGCG 341-27, is a very faint 2:1 elongated glow.  PA = 165 and 0.3’ long.



UGC 10227UGC 10227  (16 08 58.4  +36 36 40   size 2.3x0.2’   mag 15.3p)

22” at 230, 306 and 383x – Considerably faint thin glow. Even surface brightness.  Well-defined edges.  PA = 165 and 1.2’ long.  A blazing 4.8 mag star, Tau CrB,  lies 7.5’ due south.  A 15.0 mag star lies 0.6’ WNW from the center.  Use a high power narrow field eyepiece to keep Tau CrB off the field, otherwise you will have a tough time seeing it.



UGC 10297UGC 10297  (16 15 28.8  +18 54 17   size 2.0x0.2’   mag 15.0p)
