I just take my first photos using the Orion Premium 102mm ED, the telescope that makes me go to New York to realize the dream of having an apochromatic telescope.

Using a Canon EOS T2i camera attached to the telescope directly, without the use of eyepiece, I took this first photo with this telescope. The result made me really happy.
The telescope has a focal length of 710mm. I do not know exactly which equates eye sensor Canon T2I, but compared to the 18mm wide-angle 18-55mm lens that comes originally with the Canon, I guess to put the Canon attached to this telescope has become simply a lens of 710mm, which generated a 40 times zoom.
To attach the camera to the telescope I had to use two accessories that I purchased at Adorama in New York. An adapter for connecting cameras to the telescope (

The ease of use compared with the camera lens pointing to the eyepieces was impressive.
