This week we have completed a two year long project to connect the telescopes at the Astronomical Research Institute (ARI) to the high speed internet access at EIU. This was done with a direct, line of sight, microwave link over the 12 miles separating ARI and the EIU campus. This increases the bandwidth to upload images every night by a factor of at least 15.
The new wide-field camera (32 megabytes per image) took 10-15 minutes per image to up load, under the old connection. At times it wasn’t even possible as the uploader gave up and stopped running. It takes about 30-40 seconds now per image with zero failure rate. The 2 meg images on the other cameras are less than 2-3 seconds.
Just two telescopes took 12-16 hrs for upload with just the 2 meg images with the old internet. ARI never even tried the new camera on the old internet except to test the time it took. Now all three scopes can be uploaded in about 90 minutes. That’s about 2,500 images or 6 gigs of data. We are typically done by 6am!
Some day the 50 inch will be working and adding another 1.5 gigs of data per night with the large format Apogee camera. Until then enjoy a look at one of the first test pictures uploaded from the wide field camera on the 30″ telescope. the galaxy M33
