Description

This was a first test of my newly built and improved equipment for mobile use. I have owned the Star Adventurer for a long time and have used it with my Canon 700Da before. But especially in the warm summer nights the image noise became overwhelming...

So I decided to go for a cooled CMOS with a large colour sensor, which is very easy to operate with an ASIAIR via mobile phone and at the same time made the SA guidable. The mount itself got an even more stable wooden tripod and the clamps for the declination block were replaced by higher quality ones.

A few days ago the time had come: Everything in the living room was set up ready, carried out with one hand, aligned to Polaris and the first test started. For only 2 hours exposure time I am really satisfied with the result. Great, how the dust between the bright H-Alpha areas shows up. I kept M42 extra bright to emphasize the huge dynamic differences in this region.

I am very satisfied with the first light and hope that this combination (easy to transport, easy to operate and quick to use) will give me a lot of fun in the future. :-)
