Celestron R/A Single Axis Motor Drive for the AstroMaster Telescope

The hex key included in the package is all you need to install it. Where to mount it is clearly stated in the instructions. It's important to remove the corresponding (RA) knob on the telescope, otherwise the flexible aluminum motor mount coupler could break. My Celestron PS 127EQ tracked Jupiter nicely (with an 8mm eyepiece, that is. A good magnifying glass can help with this). Observers will first need to align the telescope mount with the North Star (Polaris). * This can be accomplished by turning a small knob on the motor housing. During testing, I found it tracking Jupiter for more than an hour with barely any adjustments required. Note that the only way to adjust right ascension is to loosen the r once the motor is connected. After you have locked the scope, you must turn it by hand. EDITOR'S NOTE This worked rather nicely for me after I used it a few more times. To align your telescope mount with the North Star first, you will need to do a polar alignment (if you live at my latitude this is located at a fixed 34 degrees above the horizon). A small plastic knob can be used to adjust the speed, and this is because the speed needs to be adjusted ONLY ONCE. It is basically a matter of setting the angular speed with which it tracks an object in the sky, and that rate (at a given location) is the same for all stars and planets. If you are viewing a bright object such as Jupiter, then it is best to adjust the speed at some higher magnification (8mm eyepiece). In the future, you do not have to change the speed of the telescope when you take it out again. I have made a second edit to the above Despite the fact that the original battery has been in use for three months, I still need to replace it. So far, I estimate that a 9V battery will last for about 30+ hours of You can see how it works in the pictures I posted and on the right! I have made the following changes My experience has been that when the battery is low, the speed will decrease somewhat. You should always keep a spare battery on hand since that means it's time to change the battery. This happened to me precisely at the exact moment I was trying to take a long exposure of the Andromeda galaxy. The following is an edit to version The same one I have been using for a year has never encountered any problems. Over the course of that time, I went through about three 9V battery sets, plus about one to two observation nights per week. It happens every now and then that a star or planet has a location where that small plastic box gets.

Consequently, I purchased this with the hope that I may be able to follow objects through the night sky as I venture into the realm of astronomy and astrophotography. There is at least one good thing This is a very cheap deal Compare it to your $500 or more and you'll see that it's a lot cheaper Mounts that are motorized cost more than $1,000. The product is incredibly light and portable Batteries in the 9 volt range are lightweight and easy to carry around. A tracking system would be helpful here That's all fine. There is a tracking system. Adjust the speed and you're ready to go. All you need to do is point your scope at Saturn or Jupiter. By keeping your scope pointed at them, you will stay on target. There are some negative aspects to this In construction, we are responsible for a number of services, including This item is made of plastic, so what you pay for is what you get. Obviously the 9 volt battery won't power very much so you can't expect great things from it. A tracking system for transactions can be found here It is true. There is no way to perfectly match the speed of rotation of the earth to the speed of the sun. The strength of the team The added weight of any camera equipment will cause it to slow down and make it struggle, so your speed will be off. In addition to the battery drain, it also gets affected by that. The conclusion is If you are simply interested in observing things, this is the perfect tool. The program does an excellent job on that front. It is better if you save up and buy a better tripod and mount if you plan on taking any kind of photo. All of them are correct, which is why it seems like everyone agrees. As a result, I did not listen to these people and opted for cheaper options. I tried to explain to them that they were right and I was wrong (I still cannot believe I just publicly admitted it). The last thing you want is to get stuck with it. It's better just to get a better mount unless you can live without accurate tracking.

At first, I found the product a little difficult to set up, but once I determined that I could easily adjust the speed at any time, it became easier. Here's the quick version The Earth rotates one full rotation every 24 hours. The temperature rises by 25 degrees every five I shoot 76" from the wall, so suppose your scope is the same as mine. If the laser dot moves 76*tan(1, then it should move in five minutes. (3. 25'. 121/180)) = 141. There are 65 inches in 65 feet. In 5 minutes, can you see farther from your distance than you can see now? It needs to be slowed With this setting, you should be able to get reasonably accurate tracking with only a few adjustments For most calculators, trig is always done in radians, so multiply degrees by 3 to convert them to radians. A 141/180 score. In general, the further away from the wall you do your timing, the more accurate you will be.
