HoTech HyperStar Laser Collimator This patented HoTech HyperStar Laser Collimator elevates the HyperStar collimation into a new dimension. Accurate Collimation without using a Star In order to achieve an accurate star collimation, normally the amateur astronomer requires good seeing conditions with no cloud, no wind, stable temperature, no light pollution, a well-aligned telescope mount tracking system, telescope optical tube assemble (OTA) thermal equilibrium, and a good visible magnitude star. The visual quality of the referencing star is greatly affected by the prescribed factors most of which are all in Gods hand as you can see in the photo. Adjusting the collimation is guessing game where you move between front and the back of the telescope adjusting the corresponding alignment screw and holding your breath peeping through a high magnification eyepiece referencing the concentricity of the unstable defocused image. This can be an incredibly frustrating experience. An artificial star can never simulate a real star because it is impossible to collimate with the telescope focus set at infinity. After artificial star collimation, you will need to adjust your focus back to infinity to view a real star by moving the primary mirror to a different focal position. The distance the primary mirror has been adjusted can accumulate mechanical tolerance errors. For some of the mass produced SCTs, the “sticky baffle” on the primary mirror focusing mechanism may also cause mirror-flop. If a mirror-flop has occurred, it will affect the alignment position which in turn will render the collimation useless. Ideally, it is best to collimate your optics at the same viewing focusing position without major optical displacements to correspond to the final view setting. The HyperStar Laser Collimator can accomplish this task without all the possible accumulated errors. Collimate Within Focal Distance From Your Telescope The HyperStar Laser Collimator does not require long distances to achieve high-accuracy collimation. Utilizing the installed flat mirror at the focal point (imaging sensor location), the collimator lasers double-passes the optical train and magnifies the alignment errors to a higher accuracy level. In addition, it also cuts the collimating distance in half-achieving near-field alignment process. The collimator is stationed within your telescope’s focal length directly in front of your telescope. Setting up for collimation, you will be standing between the telescope and the collimator aiming both the telescope and the collimator at each other. Then you will adjust the HyperStar collimation knobs to bring the returning lasers on the same track. This is a very convenient one-man-operation collimation task. Precision CNC Machined Panel and Components This beautifully designed instrument is precision machined from a solid block of aero-space grade aluminum. It is then hardened and anodized to keep the entire mounted laser system thermally stable allowing you to achieve accurate collimation. The rigid, ultra-thin profile, and light-weight design makes the unit portable and simple to setup and use. Upgrade Kit Available for ACT Laser Collimator Owners For users already purchased the Advanced CT Laser Collimator, you may purchase the corresponding Upgrade Kit without purchasing the laser unit. The Kit will include the proper sized HyperStar adapter and the new developed dual-sided reflector mirror for your convenience. Additional Features: Introducing the fast and precision laser collimator for HyperStar telescopeThis patented collimator elevates the HyperStar collimation into a new dimension. Accurate collimation without using a star. Collimate indoor at final view setting without taking up your precious observing time. Achieving complete optical train alignment using one device. Common Questions Q1. The HLC-925 can collimate my SCT via the Hyperstar, but can I also collimate my SCT via the standard focuser on the back ? A1. Yes, but on condition that your SCT has a 2'' focuser. In focuser collimation mode, you will need to remove the secondary mirror in order for the laser to properly co-align. You cannot use the scope in both mode at the same time. Each configuration has its own collimation calibration. Q2. To collimate via the 2'' focuser, do I need additionnal accessories ? A2. No. Since you already have a 2'' focuser, no need for additional accessories. Q3. I only have a 1.25'' focuser. How can I use this product for regular collimation ? A3. You will need the RM125 adapter to use this collimator with a 1.25'' focuser. Q4. Do I need RM2 adapter, or HK-925 adapter, to use this product in regular collimation mode ? A4. The RM2 would be a redundent item, since the HLC-925 already has the necessary accessories to collimate in a 2'' focuser. The kit already include the HK-925 adapter.
