Description

Hi everyone,

I had been looking around again for interesting compositions where I could combine multiple multiple objects and image them together and I found this when experimented around with SGPs framing and mosaic wizard.

Unfortunately there was still a little tilt in my setup when I shot this which I have resolved as well as I can now. I'm not entirely happy with the Samyang 135mm f/2 lens to be honest because the stars do not look too good in the corners but I seem to be out of options, it's just the way it is and I have not seen many better samples out there. It may not be as good as the Esprit, but you can still take some good images with it :) I stopped it down to pretty much exactly f/3.

I am a little disappointed that I could not get OU-4 imaged well, there is just a hint of it. Even without the moon in the sky the 8.5nm filter just does not cut it from my location :( Sooner or later I see 3nm filters in my future, if they were't so extremely expensive.
