Samyang 135 1st light, Orion's head.

[ollypenrice]

First light for a joint project with Peter Woods and Paul Kummer using a co-owned robotic setup based at my place. Samyang 135 lens, TS 2600 OSC camera, Avalon M-Uno mount.

2 panel mosaic, 56x3 mins for one side and 72x3 mins for the other. That's just what the sky decided to give us but it was an easy post process. Paul did the driving at capture and the pre-processing. I did the post processing on this version.

Perhaps this beautiful nebula will get more attention now that the Samyang 135 is so popular. One thing I like about shooting only in broadband and with fast optics is the way you capture a higher proportion of dust relative to emission nebulosity than when adding Ha to RGB. A Photoshop adjustment of the hue in reds is good for emphasizing the dust.

EDIT:  Please scroll down for a version 2.

Wow, a lovely image.

I should have added that the lens was wide open at F2.

As it should be 🙂 Just need a second or third one now for a really fast system...

Very nice!  I guess one of the reasons it's not so often seen is the sheer size of it? Perfect for the 135mm lens though!

Here's a version 2. I didn't use BlurXT on the first one because it damaged the stars.  In V2 I did use it and found the starless nebula was better because BlurXT helped StarXT and also improved detail. When I came to replace the stars I used the ones which had not been through BlurXT so I could get the best of both worlds. I think this is going to be my standard approach with the Samyang. Is it a bit bright on the colour??
