INSTRUCTIONS: For Re-calibrating Luna II

We all Make mistakes, weather it be forgetting to turn off the coffee pot, spilling a drink, or not hibernating a telescope. So if you have crashed Luna II or are going to use it and think you may, this is the instructions for re-calibration of Luna II our second largest telescope at NJAA.

So, you've crashed Luna II or you showed up and it was not calibrated, but don't worry this will only take 10 minuets or so! If you are already familiar with Celestron's three star alignment, don't Read any further, because you already know how to align the scope.

Step 1: Switch Position. Select a three star alignment using the 6 and 9 keys to scroll. It will now say "SET SWITCH POSITION". Press "ENTER" the telescope will now slew to the polar north. Since  Luna II on a permanent mount, it is already polar aligned, so you can just say "ENTER or ALIGN" to that; keep in mind that the Celestron paddle has instructions scrolling on it all the times and press the keys it tells you to!

Step 2: First Alignment Star. After you have completed the first step you should be on a screen that says "SELECT FIRST ALIGNMENT STAR". Using the 6 and 9 keys, scroll through the list of stars and pick a bright one or a star you are familiar with. Since this is the first star, the telescope will be considerably off mark. Use the attached Telrad finder scope and center the star with the arrow pad on the paddle. You can change the slew speed by pressing "RATE" and then the number you want. Usually I use speed 9 for centering the object in the Telrad, and 5 for fine adjustment in the eyepiece; anything below 4 is so slow that the movement will be unnoticeable- even at 3910mm! Once the star is in the center ring of the Telrad, it should be in the eyepiece. Center the object in the eyepiece in the same manor that you did with the Telrad, but with a slower slew speed. When you're done press "ALIGN"   

Step 3: Second Alignment Star. The procedure is the same as the first alignment star, but the telescope will be more exact, the Telrad may not even be needed. please REMEMBER TO TURN OFF THE TELRAD, because its annoying when you show up and the thing dosen't work!
When you're done press "ALIGN".

Step 4: Third Alignment Star: The procedure is the same as the Second alignment star however it should be pretty close to centered in the eyepiece. Center it and press "ALIGN". now you can press "UNDO" until you are at the main "CGE READY" screen, unless you want to add more alignment stars.

Congratulations! You Have Successfully Realigned Luna II! Now go go browse the cosmos with Celestron's most advanced mount and telescope!  Thanks for Reading,
