The first “technical” light

We have the first “technical” light on April 8. Images, taken in this test give information about good callimation of optical scheme. But we will continue work on this task. Mount mechanics in good condition. We can make special mention of light gathering power of our telescope. With 2 seconds exposition we have reach 18m! Of course we don’t have absolutly flat field across the image. But we can succesfully use pseudoflats to resolve this problem. The telescope will need a shroud.  The large unshielded mirror and a very sensitive camera cause reflections, such as from the moon, and a full shroud on the truss structure will be needed.

In whole we satisfied with the first test observations.

In the course of two weeks we will accomplish all planned work and telescope will be moved to it’s permanent place. The true “first light” planned to beginning of May.
