Night of 1–2 September 2026
4 objects · 1 h 58 min of light · 23:06–03:24 · Moon 76%
The telescope worked from 23:06 to 03:24 and shot Moon, Open cluster M103, Double Cluster in Perseus (h Persei) and Open cluster M35, gathering 1 h 58 min of deep-sky light.
The Moon was a waning gibbous at 76% illumination, a noticeable glow for broadband targets.
What was shot
| Time | Object | Filter | Exposure × frames | Stacked | Light |
|---|---|---|---|---|---|
| 23:06–23:07 | Moon | none | 6.25 ms × 20 | 20 / 20 | – |
| 00:08–01:30 | Open cluster M103 | none | 30 s × 136 | 128 / 136 | 1 h 4 min |
| 01:33–02:07 | Double Cluster in Perseus (h Persei) | none | 30 s × 55 | 55 / 55 | 28 min |
| 02:11–03:24 | Open cluster M35 | none | 30 s × 126 | 52 / 126 | 26 min |
What worked and what got in the way
- The longest night for Open cluster M103: 1 h 4 min of light.
- First night on Open cluster M35.
- Open cluster M35: the device rejected 59% of frames (52 of 126 stacked), usually clouds, haze or tracking.
- A bright Moon (76%) lit up the sky, which hurts broadband targets most; the dual-band filter copes better.
