Been testing out the Nikkor 135mm lens last night as we had some nice clear skies over Norfolk in the UK.

I have to say i’m impressed with the lens its super sharp at f4 and not bad at f2.8 but these images below were both taken with the 135mm prime lens at f4 and 4 min exposures. I shot around 27-37 images and stacked and edited them in photoshop.

The camera used is a Nikon D7000 which has been astro modified by myself.

Andromeda Galaxy at 135mm, slightly cropped. 27x4min subs, no darks, bias or flat frames or filters were used.
