| Zeta Herculis / HIP 81693 / SAO 65485 / Struve 2084 (Hercules) |
 |
| CCD Image (50% size) 20s exposure (single frame), 3x3 binning, C Filter 2015-05-08 00:58 h UT (#587080) 12" LX200R (at f/10.4) + ST-10XME |
| Zeta Herculis - detail Binary components are very difficult to space. 3 frames were taken (0.12s exposure, 10s apart) All 3 frames indicate an asymmetry in the star object and suggests a second star is present with an estimated spacing of 2-3 pixels from the brightest one (equivalent to 1.5 to 2.5 arc secs) Catalog details for Struve 2084, A: Mag +3.0, B: Mag +6.5 |

| Composite CCD Image (3 frames with 500% insert) 0.12s exposure (3 frames, 10s apart), 2x2 binning, C Filter 2015-05-08 00:59 h UT (#587081-83) 12" LX200R (at f/10.4) + ST-10XME |
