Skywatcher Star Adventurer – Review

Filed under Science
Tagged as , ,

I demo the Skywatcher Star Adventurer!

I contacted Skywatcher about an inexpensive, but useful, mount for tracking stars for astrophotography. I wanted a mount under $500 which could hold a star “still” for photography, at 400mm focal length, for 30-60 seconds. They sent me one for free to evaluate and here it is!

Cons:

1. Some plastic parts (not needed for operation)
2. Needs angled wedge and counter weight to be useful
3. Limited payload weight
4. Polaris finger scope light failed very quickly

Pros:
1. Light weight, easy setup
2. VERY good unguided star tracking!
3. Heavy metal construction
4. Long battery life!
5. Polaris finder scope.
6. Lots of great knobs & parts designed to simplify use

Is your toilet slightly radioactive? Maybe.

Spectrometer used was the GS1100A from: http://gammaspectacular.com/

Geiger counter used was the Inspector USB from: http://www.geigercounters.com/

Toilet was likely from a hardware store lol

I found Uranium 238, Thorium 232, and Potassium 40 in my toilet. These are normal to find.
