Description

Deneb, NGC 7000 North America nebula, IC 5070 Pelican Nebula

-----

First light of Samyang 135/2 @ f/2 with Canon450D modified (filter removed).

The main goal was to test Samyang 135/2. Outcome: at full aperture (f/2) it is excelent, aberations are quite modest and can be mainly removed during postprocessing.

Due to absense of IR-Cut filter, the red channel is bloated (I've bought Astronomic L3 EOS Clip later, which solved this problem)
