Fantastic picture David. Your tecknique combining iPhone with telescop produce a surprisingly good quality.

I tried with my D7 and 400mm, but the distance and heatdisturbance sunday was a barrier to good quality. I assume your pictures are taken in the evening?

What a bird....

Thanks for the compliments Søren! These shots were taken in the morning, between 03:45 and 06:00.

Yes indeed, it's possible to obtain astonishingly good results when iScoping. However, one should keep in mind that the quality of the glass in the scope and eyepiece is of great importance for the image quality. When I'm iScoping, I start to center the cam-lens on the exit pupil of the eyepiece. Then I zoom up all the way to 50x. It's not recommended to use the zoom on the iPhone, because it's a digital zoom which result in grain and noise etc. when cropping to the max. The iPhone 4S has a 8 MP sensor, thus it's better to zoom up on the image when post processing.
