    I think you have got the directions wrong. You were probably looking in an easterly direction. You would have seen Venus about 45 degrees and up a bit as you say. There's a nice tool called Stellarium which you can download to see what the sky might have looked like at different times. If you'd been looking westerly you might have seeen Mars - which is what I thought you meant at first, but it was not in the same region of the sky as the moon.

    Another great tool is Sky Safari. If you use it in your phone, you can point it at the night sky and it will show you what you are looking at ( using GPS/compass). Itís very good.

    A mainly digital setup with a musical amplifier and endearing 1970's speakers. A CD player that hardly ever gets used and a turntable that is good enough to remind my how enjoyable my old vinyl is. Some cables and things.

    They are producing some of the best value lenses in the world at the moment. The 135mm f2 is astounding, a definite keeper.

    The only thing that stopped me using the 14mm was the amazing lack of sharpness around the edges and in the corners. The images required so much cropping that I was better off using my 20mm but that 85mm f1.4 is one of the sharpest optics I have ever owned. In fact the only thing I have owned that was as sharp was a Zenzanon 75mm f2.8 E lens. Bloody lovely lenses, both of them.

    I havenít used the 14mm much really, only a few test shots of Milky Way. Iíd stoped it down quite a bit though.

    Itís very popular with people who like to do Milky Way landscape shots.

    Surprised to hear about your issues with it really. Maybe a dodgy one? If it was an early model (2014) it may not have been subject to the same QA standards? This is sometimes the case with volume Asian optics until they start to prove popular.

    Tony, I have noticed that the 14mm lens I owned is no longer listed. It was an ED UMC model with stunning looking glass but that resolution at the edge of the frame was shocking. It was manual focus but had connections to the camera for all of the functions. Even used at f11 the corner sharpness was dreadful. I'm sure the new models must be good given the massive hike in price.

    It was this one:

    Yes, thinking about it, I think I got the direction wrong. More like southeast. Cheers guys for the suggestions. That Sky Safari sounds handy.
