HAT-P-18 (Hercules) |
| HAT-P-18 through Astrodon Exoplanet
Blue Blocking (BB) Filter HAT-P-18: (catalog V mag mag +12.76, B-V ---) Photometric options for measuring a future transit of HAT-P-18 b are : a) use a single reference star C1 (Undef, GSC 2594:731, V Mag +10.5, B-V ??) with one check star K (Undef, GSC 2594:272, V mag +12.2, B-V ??) or b) ensemble of reference stars C1, C2, C3 C1 (as above), C2 (117, GSC 2594:496, V mag +11.653, B-V 0.912) C3 (131, GSC 2594:102, V mag +13.145, B-V 0.595) C4 (128, GSC 2594:789, V mag +12.848, B-V 0.525) with one check star K (Undef, GSC 2594:272, V mag +12.2, B-V ??) |

| Annotated CCD Image (70% size) 3 x 60s exposure (average combine), 3x3 binning, Xo Filter 2019-08-26 21:41 UT (#685024-26) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2 |
| Frames have been examined : 60s exposure in Xo (BB) filter, 3x3 binning,
max pixel ~41300 (C1 Star), ~11730 (HAT-P-18) Exposure is ok. Proposal is to go with 60s (3x3 binning), but 45s could work as well Proposal to increase W offset by further 0.5' for increased tolerance to getting C4 star in frame. (i.e. new offsets W 2.0', N -2.2') |
| HAT-P-18 - Earlier Image (2019-02-24) 20s exposure in Xo (BB) filter, 3x3 binning, max pixel ~11000 (C1 Star), ~3000 (HAT-P-18) Analysis : Exposure is much too short. Proposal is to try 60s (3x3 binning) and increase W offset by 1.5' and decrease N Offset by 0.3' to get C4 reference star in FOV (i.e. new offsets W 1.5', N -2.2') C1 (Undef, GSC 2594:731, V Mag +10.5, B-V ??) C2 (117, GSC 2594:496, V mag +11.653, B-V 0.912) C3 (131, GSC 2594:102, V mag +13.145, B-V 0.595) Check star K (Undef, GSC 2594:272, V mag +12.2, B-V ??) |
