Description

First light with the Samyang 135mm was a widefield around Messier 4. Taken through an EOS CLS filter clip on a Canon 450D. Still getting the knack of processing widefield images. Gradient removal and color calibration are difficult when so little of the field is neutral background. Will be testing the lens without the CLS filter next.

29 frames of 180s each. Taken at Evermore Farms.
