Those knobs work exactly like the screws behind the secondary mirror. Your goal here is to turn each knob until the laser is bounced back to the center of the bullseye, visible on the laser collimator. This is why it is important to attach it facing toward the back of your scope!

If you just bought a laser collimator, please make sure it is collimated! You can do that by placing it on a table not too far from a bright wall, and turning it on. Then, slowly roll the laser and see if there is any suspicious movement in the red dot on your wall. It should not go up or down, but just sideways. You can also attach it to your telescope and rotate it while it is on while watching the dot on the mirror. The dot should not move at all.

How does it work? Each screw, when being tightened, pushes the secondary mirror, giving it a different angle and so bouncing the laser in a different direction.

In Addition to its fully covert, Invisible IR night vision, the unit provides smart features like camera loop through and optional remote control via web browser. Solid design, the units offer a great solution for a variety of installations seeking a vandal resistant, IP67 weatherproof solution that is also suited for the conditions of extreme heat and cold. Built in the United States and covered with a life-time warranty will tell you all you need to know about their quality.

Make sure you do not tighten the screws too much or you will break the secondary mirror holder. It happened to us once and we had to completely replace the holder.

Description: The Constellations Handbook is a logical guide to learning the 88 constellations. Learning the constellations is difficult. Remembering them is even harder. Have you ever wanted to look up to the night sky, name any pattern of stars and be able to tell their stories?This book groups the constellations in a logical order, so that the reader can easily learn them by their origin, and see how their stories interact with one another as a group.The last pages of this book include an index of all 88 constellations, each with a slot where you can write your own personal tips and tricks in order to memorize them with ease.The Constellations Handbook is not just another guide listing all the constellations from A to Z and their location, it is the perfect companion for stargazing, and a learning journey through the ages.

Go to the back of the telescope. You do not need any tools for this, so put the screwdriver in a safe place and simply use your fingers.

Description: The Astrophotographer’s Journal is a portable notebook created for the purpose of recording observations, cataloguing photographs, and writing down the wonderful memories created by this hobby. This book contains more than 200 pages to memorialize your stargazing and imaging sessions, as well as a useful chart on the last pages to index exciting or important notes. Read back on the logs to see how much progress you have made through the months, the problems you overcame, and the notes taken to improve in the future. Just as the pioneers of astronomy did in their time, look up and take notes of your observations as you are the author of this star-filled journey.

Attach the laser collimator to the telescope, just where the eyepiece or camera would go. Make sure the target drawn on the device is facing toward the back of the telescope.

Start in the front of the telescope. This is where the secondary mirror is located. What you want to do is tighten or loosen the three tiny screws that are just in the middle of the spider veins.

Collimating a telescope is pretty easy, especially if using a laser, but first-timers might get confused by this simple process and end up breaking one of their mirrors (yes, we did).

We decided to make this tutorial, as well as a video (which you can find at the end of this post). As for most of our tutorials, this will be quick and straight to the point!

Axton AT-6T-E 940nm Covert IR Illuminator uses PoE (Power over Ethernet IEEE 802.3af) for easy universal integration with IP Video Surveillance systems. The device is light weight, housed in a compact rugged case with flexible mounting options for maximum system adaptability. Alternate models with standard voltage input and Semi-Covert IR are all also offered.
