Astrophotography with TriggerTrap

Very rarely does advertising catch my attention, but I was browsing Facebook and an advert for TriggerTrap caught my eye – it promised to allow me to control my camera from my smart phone. I had a look and I was so impressed, my “dongle” arrived the next day!

Typically, the weather forecast was wrong this morning and I was surprised to see the stars out – eager to try my new gadget, I set it up and took it into the garden. I really want to try taking photos of the stars where the stars are shown as a pin of light, so I tried this first. I set my camera to ISO3200 at f4 and told TriggerTrap on my phone to take a 30 second photo. This is the result after processing in Lightroom and Photoshop.

Seeing as I was in the garden with my equipment, I thought I would try a star trail. I set the camera to take a series of 30 second photos, left it and want back inside for a cup of tea. When I came out I discovered it had finished early because my smart phone batteries had died. This is a potential problem, but I didn’t start with a full battery and still got 35 minutes of photos. Sort of. It turned out that it only took one 30 second photo and then left a 30 second gap. Upon investigation, I discovered the camera was missing the second trigger. However, the software is very configurable so I set a delay of 100ms into it and it now works properly and takes the next photo immediately after the previous one has finished. This is the resultant 35 minutes of night, the gaps in trails caused by the missing photos. It was stacked in StarTrails.

Now I was curious as I had a series of star photos – could I create a video of it? I used Lightroom to string the photos into a sequence and created this. Please forgive the incorrect copyright date – I really must edit that! The video is really very short but I am very impressed and want to try it some more! The reason it gets lighter is because dawn is approaching.

Please set the video to 1080HD and full screen to watch it properly.

In summary, I am absolutely delighted with my new TriggerTrap gadget and will hopefully be heading out to Gower tonight to try it for real…
