However, several telescope manufacturers have recently developed telescope systems that are calibrated with the use of built-in GPS, decreasing the time it takes to set up a telescope at the start of an observing session.

However, if light travels at finite speed, the Earth, and therefore the eye piece of the telescope, moves from E to E ′ during the time it takes light to travel from S to E. Consequently, the star will no longer appear in the center of the eye piece.

" However, after the advent of the telescope showed problems with some geocentric models ( by demonstrating that Venus circles the sun, for example ), the Tychonic system and variations on that system became very popular among geocentrists, and the Jesuit astronomer Giovanni Battista Riccioli would continue Tycho's use of physics, stellar astronomy ( now with a telescope ), and religion to argue against heliocentrism and for Tycho's system well into the seventeenth century ( see Riccioli ).

However, since inexpensive and adequately stable computer-controlled alt-az telescope mounts were developed in the 1980s, the Nasmyth design has supplanted the coudé focus for large telescopes.

However, it can be viewed with a small telescope.

However, through the efforts of George Davidson, president of the California Academy of Sciences, Lick was persuaded to leave the greatest portion of his fortune to the establishment of a mountain top observatory, with the largest, most powerful telescope yet built by man.

However, this is a structurally poor design and becomes more and more cumbersome as the diameter and weight of the telescope increases.

However, in each case the companion star could not be resolved using a telescope, and so these double-star systems were designated spectroscopic binaries.

However, very similar-looking alterations in the systems of long vowels in the West Germanic languages greatly postdate any possible notion of a proto-language innovation ( and cannot readily be regarded as " areal ", either, since English and continental West Germanic were not a linguistic area ).

However metals are often readily soluble in each other while retaining the metallic character of their bonding.

However, schlerotia ( what are termed as " truffles "), mushroom spores, and active mycellium cultures remained legal and are readily available in the " smartshops ", the stores in the Dutch cities that sell legal drugs, herbs and related gadgets.

However, it exhibits sufficient significant differences to merit its classification as a separate language ; for instance, it is not readily understandable to Polish speakers unless written.

However, Orbison was readily available to sing, and often became the focus of attention when he did.

However, the air cycle machine is very common on gas turbine-powered jet aircraft as cooling and ventilation units, because compressed air is readily available from the engines ' compressor sections.

However, the definition involving energy can be readily extended to yield information about the stability of the equilibrium state.

However, the MBTI continues to be popular because many people are qualified to administer the instrument, it is not difficult to understand, and there are many supporting books, websites and other useful sources which are readily available to the general public.
