One of the 3 first light images of the new Trebur T1T. The telescope is located near the airport of Frankfurt in the center of a little town. Light pollution is bad and local seeing may suffer also from the buildings. However it can be shown that a lot of these disadvantages and moon conditions can be partially compensated by the brute light gathering power of this telescope.

The extreme tracking performance of this telescope allowed to track the telescope blind without any tracking corrections for 2m integration times. After a better polar alignment maybe 10m will be possible.

Image:
The H-alpha exposure was partially added to the Red-Exposure and to the Luminance channel to bring out the exploding Hydrogen-Cloud.
