With the commissioning of Redeye in January, 1993, we expect that the cameras will be in service for roughly 5 years, with perhaps a detector upgrade somewhere along the line. In this time Redeye may be used as much as all of the other array detectors (CCDs) combined, since they represent the only CFHT window to the 1-2.5 m domain as facility instruments. Early on we decided that Redeye would not be a "do everything" camera, opting instead for a camera that offers exceptional sensitivity in a dewar that can be mounted to a variety of existing instruments, that can be built in a reasonable amount of time on a limited budget. We think we have been successful to that end, building two cameras for nearly the price of one. At the beginning of the project it was decided to pursue the rapid development of a 1-2.5 m non-thermal camera first, then perhaps build a more complex 1-5 m camera sometime thereafter. With the recent work on 8-10 m class telescopes on Mauna Kea though, the competitive viability of a facility thermal camera at CFHT is questionable. As a result, the second generation CFHT infrared camera will probably also only work in the 1-2.5 m range but will use a much larger format array and may include dispersing elements to support spectroscopy.

Be sure to use the UNIX command 'uncompress filename' on the transmitted files before printing them. The postscript files are stored in separate chapters (with *.Z suffixes to indicate compression) so users can extract only the parts of the manual they are interested in. It is recommended that the Table of Contents be transmitted first, then printed out locally. From there any or all chapters that look useful can be transmitted. Be aware that the manual contains a large amount of embedded graphics, hence can take a fair amount of time to print on most postscript printers.
If a hard copy of the manual is not available on the summit (which tends to be the case since manuals develop legs rather quickly) it is straightforward to generate one locally with Wiki and the summit Sparc printer. To do this, first rlogin to Uwila from Wiki then 'cd ~ftp/pub/cfht-manuals/redeye'. Copy the files (i.e., chapters) you want to your local Wiki directory, then 'uncompress' and 'lpr' them to the summit printer via the command 'lpr -Psps filename'. Users with a X-environment available and a postscript viewer can peruse the manual without actually printing it out. The program "ghostview" is available on Wiki on the summit for this purpose.
Thanks to the software used to create this manual, modifying it should be much less cumbersome than past CFHT manuals, which relied heavily on "physical" cuts/pastes of text and graphics. Accordingly, during the first 1-2 years of Redeye's release, we expect to amend the manual periodically to reflect new performance specifications or observing modes available. After that, the manual will likely reach a "stable" era as Redeye matures.In order to determine how up-to-date the current version of the manual stored on the anonymous ftp disk is, there is a version number on the front page. Please check this version number before ftp'ing a new copy. As new versions are created the file "readme" will be updated to briefly describe new amendments or changes to the manual. Finally, while this manual represents the "first line" of information about Redeye to the CFHT community, if you cannot find the information you need about the cameras, or are concerned about getting the most up-to-date specifications possible, as always feel free to contact the CFHT technical staff or a resident astronomer. In particular, Dr. Jean-Luc Beuzit (firstname.lastname@example.org) is currently on support duty for the Redeye cameras.
