Make sure that the tripod of your telescope mount is as level as possible. An uneven tripod will result in an inaccurate position of your mount in relation to the altitude scale. Many german equatorial mounts have a bubble level built-in.
I like to place a level on the tripod before the mount is attached and make sure it is level on each axis. It is important to note that the tripod needs to be pointing North before leveling. I prefer to make a visual observation at nightfall to align with Polaris. If you are setting up during the day, a compass will do the trick.
Leveling the tripod before attaching the telescope mount. This is the coordinate we will use to adjust the position of the telescope mount to align with the North celestial pole. The telescope mount should have a latitude scale posted on one side, with an indicator of what latitude your mount is currently in line with. You will need to adjust the mount to your current latitude using its altitude adjustment bolts.
The altitude adjustment bolts can be a little difficult to get the hang of. To turn one bolt, the other has to be loosened. If your telescope has already been attached to the mount, turning these bolts can be hard. The overall weight of the telescope attached will determine how hard it will be to turn the bolts. By this point, the telescope mount should be roughly aligned with the height of the North Star. You may be able to crouch down and see Polaris through the polar scope reticule at this point.
Depending on the telescope mount, the view through the polar scope may be obstructed when the telescope is in the rest position. A mobile app such as PolarFinder will tell you the exact spot to position the North Star for a near-perfect polar alignment. It will display the correct position of Polaris in relation to the North celestial pole.

Countdown 19,x Free, for Mac, Windows. Polar device rewards you by giving feedback and showing the benefits of your activity. If you wear your Polar device at night, it also tracks your sleep time and quality restful or restless.
Polar device uses an internal 3D accelerometer to record your wrist movements. It analyses the frequency, intensity and regularity of your movements together with your physical information. Polar device tracks all your activities, everything from light chores to intense sports. It spots from your wrist movements when you're active and when you're sitting and resting.
It's specifically your wrist that needs to move when you're being active, in order for your device to understand your activity. This means also that the device cannot track how heavy a load you carry, or how steep a hill you climb or what force you use when strength training. To have your device detect activities like cycling, weight training, yoga or walking while pushing a stroller, use it with a heart rate sensor.
That way you won't miss observing those activities where your wrist is not moving but you're still being very active. Polar device gives you an activity goal each day and guides you in reaching it. Your activity goal is shown as a bar that gradually fills to show how close you are to your goal. When the bar is full, you've reached your goal. The activity goal is based on your personal data and activity level setting, which you can find in the Daily Activity Goal settings in the Flow web service.
The Daily Activity goal setting lets you choose from three activity levels see number 1 in the image below the one that best describes your typical day and activity.
Below the selection area see number 2 in the image below , you can see how active you need to be to reach your daily activity goal on the chosen level. The active time you need during the day to reach your goal depends on the level you have chosen and the intensity of your activities.
Meet your goal faster with more intense activities or stay active at a slightly more moderate pace throughout the day. Age and gender also affect the intensity you need to reach your activity goal. The younger you are, the more intense your activity needs to be. If it seems that your activity goal is very easy to reach, and your current typical activity level choice is Level 1, you can change it to Level 2.
This way you will get a more demanding activity goal. Your Polar device gradually fills up an activity bar to indicate your progress towards your daily activity goal. In addition, it shows your active time, calories and steps.
Polar device also gives you options for reaching your goal. It tells how long you need to be active if you choose low, medium or high intensity activities.
In the device, 'up' means low intensity, 'walking' means medium intensity, and 'jogging' means high intensity.
You'll find more examples for low, medium and high intensity activities at the Polar Flow web service and Flow app.
For more information on how your activity is shown on the device, see the user manual for your Polar device. Check your daily activity status instantly on the go from the Flow mobile app. You can see the activity overview, check burned calories, steps and sleep time. You can also follow your weekly and monthly status in a clear, visual format.
Flow app syncs and stores all your activity data to the Flow web service, where you can analyze every detail and follow your long-term progress. Flow web service stores all your activity so that you can easily analyze your daily and long-term physical activity. Activity information is shown in Diary after you sync your device. You can choose to see your activity in day, week or month view, along with a daily, weekly or monthly Activity summary.
You can open the day view by clicking a day in the month view. The month view summarizes each week see number 2 in image above. You can open the week view by clicking the week's summary. In the same way, the week view summarizes each day, and you can open the day view by clicking the day's summary. If we allow the angle to make as many complete rotations about the axis system as we want then there are an infinite number of coordinates for the same point.
Next, we should talk about the origin of the coordinate system. In polar coordinates the origin is often called the pole. Well start out with the following sketch reminding us how both coordinate systems work. This gives,. Summarizing then gives the following formulas for converting from Cartesian coordinates to polar coordinates. This is not the correct angle however. Therefore, the actual angle is,. This one is a little trickier, but not by much.
However, there is no straight substitution for the cosine that will give us only Cartesian coordinates.
