A night down at the Cape

I took this on Wednesday night down at Cape Schanck with an 18-55mm Canon kit lens. My intention was to use a Samyang 14mm to obtain a nice wide field of this rugged coastline under moonlight but I forgot to put it in the car! The only solution was to do a mosaic to roughly construct a field of view with the 18mm similar to what the 14mm would have made. The stitching of frames is rather tricky with a wide lens because of the distortions the lens produces to achieve a wide FOV. Each overlap was different top and bottom so there was some stretching involved in Photoshop Layers to scale and align the stars as best I could. Adding to the difficulty, the lens produced varying colour casts which were hard to match at the overlapping frames.

This photo is a blend of a 2 min exposure of the foreground and four frames tracked for 1 min with a Nano Tracker, both at 1600 iso, f 3.5, with a modded Canon 550d under a first quarter moon.

Good shot Michael - you can clearly see the pointers and southern cross. Cheers, John W.

Thanks John, there was a strong onshore wind blowing which carried with it a fair bit of sea spray, reducing transparency. Along with the quarter moon, most of the fainter stars were difficult to see.

Well done. Great set up shot with lots of great colour and detail. Particularly when you made do with a kit lense.

I too accidentally left my Samyang 14mm at home on a trip down the coast on the clearest night ever. I tried the kit lense but wrong f ratio and focus was a nightmare .

You have done exceptionally. I donít think I could salvage my night like that. Looks just like a fast 14 mm.

Thanks for your comments Ray. Quite a coincidence that your trip to the coast was associated with the same issue of forgetting the 14mm and having to use the 18-55mm Kit lens, a bit spooky even . I had to remove some CA from some of the stars but it wasn't too bad considering it being a cheap lens. It's all about improvisation to overcome problems and make the most of what's available at the time.
