Here is it. The Skywatcher Star Adventurer. A small equatorial, RA-motorized star tracker (no DEC motor) with a payload capacity of 5 kg and it comes with some functions for time lapses (like slight panning during shooting). But at the moment I’m more interested in long exposure imaging 😀
In my first tests I could exposure 2-3 minutes. After re-alignment the North Celestial Pole more accurate, exposure times of 4-5 minutes is no problem (with 75mm focal length and 45° declination).
In my opinion it is a cheap but accurate and ultra portable mount up to 200mm, guided up to 600mm focal length. To start (deep) sky photography the best investment for me.
Experiences with my Star Adventurer (unguided)
- 50mm, 100% usage of the taken images, up to 5 minutes exposure time
- 100mm, 90% usage, 3 minutes exp. in average
- 200mm, 60% usage, 90 seconds exp. in average
- 280mm, 30%-40% usage, 60seconds exp. in average (200mm + Kenko 1.4x converter)
- 400mm, 1% usage (useless unguided)
First test, 185mm, f/5.6, ISO1600, 120sec, Persei Cluster:
