About this deal

There are differents ways to specify a objects location on the celestial sphere, These differ in their choice of fundamental plane, which divides the celestial sphere into two equal hemispheres along a great circle. With a mission to encourage wellbeing for everybody, it takes a dynamic approach to projects to offer affordable, long-term fitness opportunities.Sunshine Gym works closely with clients to develop outdoor fitness areas that suit a wide variety of needs and abilities. The freely-accessible range includes cardiovascular exercise units, strength building stations, and equipment designed for light stretching and warm ups. After assembling mount it to a tripod and go outside. The tripod will be a major tool because you will use it to align the setup with the north celestial pole. After going outside away from city lights, adjust the Laser to an upright position by turning the motor with your hand.

Sky-Watcher offers simple solutions for users who would like to attach their smaller telescope to a convenient computerized system but do not wish to deal with the weight of the HEQ5 or EQ6 mount. The EQ5 Pro mounts use the same Go-To system found in the HEQ5 and EQ6 Pros - SynScan. It allows you to point the telescope at a specific object or even tour the skies with a touch of few buttons. The EQ5 SynScan mounts are the perfect instrument for novice visual observers to enjoy astronomy with minimal setup time and in-depth knowledge of the night sky. For novice users, the user-friendly menu allows automatic slewing to 42900+ objects. Note: I could use serial communication between the two Arduino's but since the analog pins are used by the inputs I had to use digital pins. set date-time according to (seconds, minutes, hours, day of the week, day of the month, month, year) The coordinate indicating where an object is between the celestial poles is declination. Measured from the celestial equator it ranges from 0° to 90° at the north celestial pole and to -90° at the south celestial pole.[4] Sky-Watcher includes an illuminated polar finderscope to aid the polar alignment process. The finderscope features a circular grid reticle for the northern hemisphere, consistent with todays popular polar alignment apps. For astronomers in the southern hemisphere, the constellation Octans is built into the reticle as well. Even without a clear view of Polaris, the EQ Pro can be polar aligned using our SynScan hand controller. Simply choose one of the visible stars listed and use the latitude adjustment screws to center it in the eyepiece.

I did not get into details since this is something like an introduction to positional astronomy. If you want to learn more I will include the links that were really helpful for me. There are also problems that you can solve to practice what you have learned. This way you will be able to calculate the coordinates of a star with a given latitude and time. Using our proprietary SynScan hand controller, the EQ6-R Pro provides a user-friendly interface with automatic slewing to over 42,000 objects in the night sky. The hand controller can also connect to a computer using the supplied RS232 cable (USB adapter available), enabling computer control with most astronomy programs. For the astrophotographers looking to reduce Periodic Error, the SynScan hand controller has built in PEC training that can be configured while in the field! Like coordinates on earth (longitude and latitude), two coordinates define a point on the celestial sphere, Declination, and Right Ascension. Like Earth, the celestial sphere also has an equator, north pole and a south pole called celestial equator, celestial north pole, and celestial south pole. These are just projections of Earths equator,north pole and a south pole on the celestial sphere. As a market leader, Sunshine Gym works to create safe, interesting and attractive workout areas which as well as boosting people’s fitness inspire social inclusion and respect for surroundings. Multi gym arrangements can encourage class and group workouts among families, friends and colleagues while the right mix of equipment ensures individual users stay motivated.

Latest model with USB port. 

But first I had to find a way to precisely point the mount to given degrees. The main idea was to use step motors and give them a specific step to take. But after a few tests I found out that the pointing was not accurate(a few degrees).

The EQ6-R Pro uses Stepper motors with a 1.8° step angle and 64 micro steps driven. Stepper motors are quieter than servo motors, providing accuracy up to 1 arc minute without waking your neighbors from buzzing motors. Sidereal time is different than solar time. A sidereal day is about 4 minutes less than a solar day. Because of the Earths orbit around the sun. I'm not going into details on how to calculate Sidereal time. I will include some links below if you are interested. You can use a Sidereal calculator. Local Sidereal Time (LST) indicates the Right Ascension on the sky that is currently crossing the Local Meridian. So, if a star has a Right Ascension of 05h 32m 24s, it will be on your meridian at LST=05:32:24.[5] In other words, if you face the north at 0h Local Sidereal Time. the Vernal Equinox Point(0h Ra) will be right above you. to understand it more clearly open this animationThe Synscan Hand Controller fell through a traversable wormhole from the 80s. RJ11 as a data connection in 2023 is an.. uh, choice. There's an RJ45 right next to it! Why not two of them?
