How do you test for polar alignment?
The method is straightforward, but it does require some time and patience.
- First, aim the mount’s polar axis roughly at Polaris.
- If the star drifts south in the eyepiece, the polar axis is pointing too far east.
- If the star drifts north, the polar axis is too far west.
How do you polar align a telescope during the day?
One good way is to use the Sun. Carefully level your mount with a bubble level and set the polar axis to the latitude of your site. Hang a weighted string from the mount (between the tripod legs) and lay a protractor on the ground,centered under the string.
How do you rough polar align?
Rough Polar Alignment Identify your telescopes declination axis and note there is a scale around it. Rotate the telescope about this axis until it’s at 90 degrees. It should now be pointing along the polar axis.
How close is a good polar alignment?
A polar alignment within 1 arc minute of the pole is usually considered to be excellent and good enough for long exposure imaging.
How accurate does polar alignment need to be?
For almost all work except very near the poles, polar alignment of 2′ or less is sufficient. That is reasonably easy to attain.
How do you use the polar scope pro alignment?
How Do I Polar Align My Star Adventurer Pro with Polar Scope Align Pro?
- Tap on the Gear icon.
- Tap on Change Polar Scope Reticle.
- For the Star Adventurer Pro, select the Orion/Skywatcher 2012-2032 reticle.
- Tap on Done to go back.
- Tap on Reticle Instructions to learn how the reticle works and tap Done when finished reading.
How did NASA get past the Van Allen radiation belt?
The Earth parking orbit is under the inner radiation belt; it traversed the inner zone of the outer belt in about 30 minutes and through the most energetic region in about 10 minutes. On its way back, its trajectory was optimised such that Apollo 11 would steer clear of the belts as much as possible.
Can humans pass through the Van Allen Belt?
No, it is not impossible. 9 Apollo missions sent humans through the Van Allen belts, and the astronauts survived just fine. The radiation levels in the Van Allen belts are high, about 1000 times higher than normal space. Still, so long as one doesn’t stay in that region for a long time, one is perfectly okay.
