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

I Saw the Sun!

I took a bunch of photos of the Sun using a Coronado sun telescope and manually stacked them using GIMP. The result was quite nice, I think you can see a large sun spot as well as a prominence (bottom of sun).

So, how big is this prominence? I measure that it rises ~30,648.94 miles above the sun and has an apparent width of around ~202,282.98 miles!

That prominence is 3.87 Earths in height and 25.56 Earths long!!!

Math:
Diameter of sun image is 987px.
Avg. diameter of sun: 864300 miles.

So, 864300 miles / 987px= 875.6838905775076 miles/px
Maximum height of the prominence is 35px

Therefore, 35px * 875.6838905775076 miles/px = 30648.93617021277 Miles
Call is ~30,648.94 Miles

Astrophysics Video Coming Soon!

My Astrophysics Equipment

Okay folks, I know you been waiting for a video for a while and I’ve been lazy and working on my books and not producing one. I have an upcoming video about astrophysics that I helped put out for you pretty soon. In this video, I’ll be detecting various radio phenomena from space using my nuclear physics equipment. Depending on whether or not I ever get a clear night, I may also do a video on using a telescope to capture pictures of the stars. I’m also working on some software that will allow me to produce nice thermographic images of the sky. We shall see.
