- Condition: VG6
- Location: Home, Spearfish: 44.49, -103.87
9:50PM
- Target: ζ Coronae Borealis
- Const: Corona Borealis
- RaDec: 15h39m +36.38
- Type: Star (Double)
- Scope: ST80
- Setting: 57x
- Double: AB: 315°
Started by zeroing in on α Coronae Borealis and increasing declination until I hit the expected star pattern.
10:05PM
- Target: σ Coronae Borealis
- Const: Corona Borealis
- RaDec: 16h14m +33.52
- Type: Star (Double)
- Scope: ST80
- Setting: 57x
- Double: AB: 260°
Started by navigating to ν Coronae Borealis (since it’s very distinguishable) and decreased RA from there.
10:16PM
- Target: M 13, Hercules Globular Cluster
- Const: Hercules
- RaDec: 16h41m +36.28
- Type: Globular Cluster
- Scope: ST80
- Setting: 57x
Navigated to ζ Herculis and increased declination until the cluster appeared. Not the best night for viewing a cluster, but I was anxious to see one again. Very bright and seems to be densely packed.
10:25PM
- Target: ρ Herculis
- Const: Hercules
- RaDec: 17h23m +37.09
- Type: Star (Double)
- Scope: ST80
- Setting: 75x
- Double: AB: 330°
Increased RA from M13 until π and ρ came into view.
10:35PM
- Target: δ Herculis
- Const: Hercules
- RaDec: 17h15m +24.5
- Type: Star (Double)
- Scope: ST80
- Setting: 120x
- Double: AB: 300°
Moved behind a power-line right after I located it, so I had to wait for a few minutes until it appeared again. Had trouble distinguishing the sibling from other background stars in the FOV.
11:01PM
- Target: 95 Herculis
- Const: Hercules
- RaDec: 18h01m +21.36
- Type: Star (Double)
- Scope: ST80
- Setting: 92x
- Double: AB: 260°
Navigated to ν Herculis and decreased declination. Very neat split. Both are almost of equal size and magnitude.
11:14PM
- Target: M 92
- Const: Hercules
- RaDec: 17h17m +43.8
- Type: Globular Cluster
- Scope: ST80
- Setting: 57x
Increased declination from π Herculis. At first glance, appeared to be smaller than M13. Overtime using AV, I got the impression that the size was almost as large as M13 but more faint around the perimeter.
