For anyone who is interested, At the last SLAS meeting, a question was raised regarding the data projector which we plan to buy, and its resolution. The trade off is lumens to resolution, between a projector having a 1024 X 768 pixel resolution with 1200 lumens, vs an 800 X 600 Pixel projector having 2000 lumens. Inkleys has kindly offered to demo the two projectors for us tomorrow (today?, Monday)at 12:00 noon at its store at 2150 South State. I've been told that the difference in lumens will be so big, that the choice will be obvious. However, if anyone else would like to see the demo, feel free to meet us there. I understand there was no acrimony in the question raised, but it was a good question, and one we thought we should look at. The technical guy at Inkleys said he could talk till he was blue in the face, but the best way to see the difference that the greater lumens would make, was to see it in person. By the way, many laptops cannot display at greater than 800 X 600 resolution, and any laptop will be able to back down to that resolution, so useability will not be an issue. Thanks, Josephine Grahn
Jo et al; Just my $.02 worth when it comes to projectors; Here at my office we bought a really nice projector from Inkley's that has 2000 lumens. It's fantastic. I've used it in a dark room and I've used it in a well lit auditorium without any problem. The machine we purchased is pretty much top of the line as we use it nearly every day. In addition to 2000 lumens, the resolution is 1024 x 768, so you can imagine how nice the image is. I wanted to go to the demo, but couldn't; I'm curious as to how the lumens vs resolution debate went. I can see both sides of the fence for a SLAS application; more lumens would be nice for large room presentations. However, higher resolution would be nice for the finer images we often look at as astronomers. Your thoughts?

Joe, I went to the demo at Inkleys yesterday and agreed with the assessment of Lowell, Josephine, and Bill Cowles regarding the projector. Although it would have been great to have the increased XGA (1024x768) resolution as well the brightness of the higher lumens, the budget did not allow for both so a choice had to be made. The contest between the two was hands down given to the increased lumens though. In comparisons between a 1200 lumen projector and the 2000 lumen projector (both at native 800x600 SVGA resolution) the 2000 had much better contrast, the colors more brilliant, much easier to read text and diagrams at a distance (especially under florescent lighting), and seemed to have increased resolution in its own right. The comparison between the 2000 lumen SVGA projector and the 2000 lumen XGA was not quite so obvious. Fine detail (especially small font) was definitely easier to see in the XGA machine set to its native resolution and the SVGA machine compressing the image. But when the laptop itself was set to 800x600 resolution the SVGA in native mode performed superbly. I'm quite delighted with their decision to purchase the 2000 lumen/SVGA projector and am looking forward to seeing it in action next year. I think the club will be very happy. Many thanks should continue to go to the Alcon Committee for their great suggestion and generous purchase. Kudos to Bill Cowles and Inkleys for their part in making this happen too!

Your thoughts?
Dave & others- Sounds like you were able to get a machine that performs well and from your other posting you got a great deal! How can you beat that? The demo is the key; when I shopped around for the one we got here at the office I looked a number of them, with the lights on/off, images, text, the whole enchilada. Seeing is believing, and the guys at Inkley's are terrific to work with. So, when is 'first light'?
