All-sky photometry furnishes a stringent test for photometric site quality and West Mountain has proven to be an excellent location for astronomical research that is still convenient to the main Provo campus. WebAn autocollimator is a single instrument combining the functions of a telescope and a collimator to detect small angular displacements of a mirror by means of its own collimated light. You will wonder how you ever lived without one. The site itself is far enough to the west of the developed areas along the Wasatch Mountains so that it continues to produce high quality research observations.

Axial beam lasers are subject to minor centering errors Autocollimator for $165. The device has a motorized focusing knob controlled by a supplied software. The autocollimator scale is set up to measure mirror tilt, not the beam angle. The vendor claims that getting a darkened autocollimator background is always an indication of excellent collimation. WebPLX Autocollimator and Alignment Telescopes are high-accuracy measurement instruments capable of resolution down to fractions of an arc-second. This usual configuration is known as infinity setting, i.e the autocollimators are focused at infinity. Connects to your computer via a USB port. and Autocollimator (PDF).

Collimate either day or This telescope was purchased in the 1950s and placed atop the BYU Eyring Science Center where it produced high quality photometric observations until local light pollution and encroaching buildings necessitated the move to the remote site at West Mountain. In fact, we offer collimation tools from the most trusted brands in the industry, including Celestron, FarPoint, Bobs Knobs, HoTech, Baader, as well as many others. and autocollimation supports (need only be done once) using the laser in single beam mode. Utah Lake borders the west and north. detect. pass". time needed to collimate a medium sized Newtonian was greatly reduced and the If you are considering whether to invest in a Catseye autocollimator or one of the cheaper clones you will find his advice useful: All autocollimators have an eyepiece case, a mirror, and all show multiple reflections of the primary mirror center spot. The WMO was built in 1981 when it became apparent that there were no longer opportunities to make dark sky research observations from the Provo campus. This type AKR MD is used if a straight viewing telescope cannot be used from ergonomic point of view. In 2006, the BYU astronomy group was awarded a National Science Foundation PREST (AST 0618209) grant to upgrade the main telescope at WMO.

WebThe PLX ACT-25B Electronic Autocollimator and Alignment Telescope is a robustly designed all-in-one unit with exceptional focusing range. For example, stars will not come to a pinpoint focus and planets will look slightly hazy. An average quality autocollimator will not add value above and beyond other good collimation tools. Jason also added some comments regarding the way some autocollimators are marketed: I have spent a significant time studying the autocollimator reflections and how best to interpret them. These features specifically enhance the unit's accuracy and ease of use when autocollimating. Our The two reticles of an autocollimator with fixed focus setting are positioned in the focal plane of the corrected objective lens, so that the emerging beam is parallel. Although the population along the Wasatch front is growing, most of this growth is to the north. is CNC machined from solid aircraft aluminum, then gold anodized. In general the observatory is not open to the public. Furthermore, WMO has been shown to provide both graduate and undergraduate students with experiences at a working research observatory that are comparable to what they could get at other major observatories around the world. Through the mid 1990s, research and teaching were vigorously pursued at West Mountain. The same vendor continued claiming that having a primary mirror center spot is optional with an autocollimator.
