The image above was taken a couple of nights ago as we finished our night shift, observing at the JCMT. It’s a panoramic image, three images going left to right – can you spot the join? – taken from the summit of Mauna Kea. In the distance is Mauna Loa.
For panoramic images I use a great piece of software called hugin. It’s donationware, but it is a great piece of software and although it doesn’t always produce a final stitch product (which has only happened to me a few times) when it works, it works better than any other piece of stitching software I have used before. I must admit though, the exposure blending didn’t work marvelously well this time (you can see the joins, right?) probably because the light changes quite quickly at that time of day.
This was a hard exposure to get right because the ground is dark and the sky is bright. I had no choice really but to expose for the sky as that’s where all the interesting detail and colours are, and hope that I could recover the rest in my Lightroom. I like the final result.
