Perhaps you are the one who needs to do more research. First of all, I never claimed one telescope would work.
Second, your link is about auxilliary telescopes. The combination of all four telescopes (VLT interferometer) began in 2002....
http://www.scienceblog.com/community/older...F/20022370.htmlThat's why Dr. West mentioned this could be another option, if one scope didn't succeed at first.
turbonium, I notice that you are ignoring the facts that don't fit your claims.
The auxiliary telescopes ARE part of the VLTI. Without these 'scopes the VLTI does not operate at full resolution. The second auxillary 'scope did not come on line until 2005. There are now actually four of these auxillary telescopes. In fact it is these telescope which actually do most of the VLTI work, the large scopes are used only occasionally:
QUOTE
Although the four 8.2m diameter Unit Telescopes can be combined in the VLTI, most of the time these large telescopes are used for other purposes. They are therefore only available for interferometric observations for a limited number of nights every year.
In order to exploit the VLTI each night, four dedicated ‘Auxiliary Telescopes’ (ATs) of 1.8m diameter are available. The ATs are mounted on tracks and can be moved between precisely defined observing positions. From these positions, their light beams are combined in the VLTI.
Source:
ESO - ParanalYou claim that the combination of all four telescopes started in 2002, but it is clear from your link that this is not really true, it
was being tested in 2002, it was certainly
not operational. From
YOUR link:
QUOTE
During the nights of September 15/16 and 16/17, 2002, preliminary tests were successfully carried out during which the light beams from all four VLT 8.2-m Unit Telescopes (UTs) at the ESO Paranal Observatory were successively combined, two by two, to produce interferometric fringes.
QUOTE
While there is still a long way ahead to the routine production of extremely sharp, interferometric images, the present test observations have allowed to demonstrate directly the 2D-resolution capacity of the VLTI by means of multiple measurements of a distant star.
QUOTE
Much valuable experience was gained during those two nights and the ESO engineers and scientists are optimistic that these test observations with the numerous components of the VLTI will continue to progress rapidly. Five intense, technical test periods are scheduled during the next six months; some of these with the Mid-Infrared interferometric instrument for the VLTI (MIDI) which will soon be installed at Paranal.
My emphasis in all cases.
The fitting of the adaptive optics, which are integral part of the VLTI was not started until 2003, again from your link:
QUOTE
Next year, the first adaptive optics systems for the VLTI will be inserted below the telescopes. By drastically reducing the smearing effects of the turbulent atmosphere through which the light has to pass before it enters the telescopes, this will further "stabilize" the imaging and increase the sensitivity of the VLTI by a factor of almost 100.
Research is about more than cutting and pasting. It is about reading and understanding the material you post. You clearly have not done this. I suspect you are one of the more honest HBs, your half truths (as seen in the quote above) are the result of genuine lack of research and understanding rather than a desire to deceive. That however is irrelevant, it doesn't change the fact that what you have posted is half truths.
