Having a lot of fun with this Samyang lens, something to keep me occupied during lockdown and being stuck in Bortle 8. The stars are elongated top left, but I don't think I can do anything about it, as no room for manouvre, am on the cusp of being able to get focus as it is (focus ring won't turn any further), so no chance of increasing the space or anything.
Taken over 3 nights, due to having to wait for it to rise above the house tops, and dawn starting to arrive at 3am.

Very nice Carole. You are getting good mileage out of that lens and we've had nothing but good weather since you got it!
Thanks Duncan,

I like that Carole, nice colour and a beautiful area of the sky. It's on my list for this year as well.
Would be really good if you could get that spacing / tilt issue sorted !

would be good, but I don't think it's going to be possible. I am pretty sure any further spacing will make focussing impossible.
I could try stopping it down a bit more, but am really loving the speed of these optics. Maybe cropping out the bad corner and getting used to centring the FOV to accommodate this, will have to be the best I can do.

Again a great shot with that lens 8)
Roberto
Somehow I missed this one.
It's a great result Carole and I love the colours. That lens gives you a very useful field of view.
Mark
Thanks Roberto and Mark.

The thickness of the filter makes all the difference at that focal ratio or you could always try a thinner lens adaptor With some spacers...
