Aurora - on the move for the right observation spot

Around new moon in March I went with my brother on a “Aurora - the northern light” trip to Tromsø in Norway. Tromsø - at a latitude of almost 70 degrees - is the largest city north of the arctic circle. With a large airport, hotels and a very good infrastructure it is one of the best places to visit to see the northern light.

Tromsø

We had three nights to observe the light. But the weather was terrible. Rain and storm! During the second day we examined the weather forecasts and talked to the local experts. They all said: “Drive away from the coast into the highlands towards Finland”. On saturday we started driving eastwards already in the afternoon. We arrived at the small Finnish village Kilpilsjärvi just around sunset and suddenly the sky cleared. After a dinner at the small restaurant we went outside: And there - shining right through the twilight - we saw the most beautyful Aurora. For one hour we had the greatest display of this celestial wonder. And we were lucky - after one hour the snow came and we drove 3 hours back to Tromsø in heavy snow.

This trip proved the value of having mobile equipment that can be moved and set up fast to be ready when the opportunity appears.

QSI-583 camera and TTS-160 - a great match

A couple of weeks ago I had the opportunity to use a QSI-583 camera together with the TEC-140 APO on the TTS-160 mount with telescope rOTAtor. The camera is a great match for this setup because the compact integrated filter wheel makes it easy to transport and setup.

 The images was acquired through Maxim DL 5 Pro that also took care of the guiding. The guiding setup was a TeleVue TV-60 telescope and a QCam5 camera.

 

As I only had two clear nights with the camera I decided to try several objects instead of doing the very best on one object. The guiding and de-rotation worked perfectly so no time was wasted.

Below is some of the images. The processing was done by my friend Jesper Sørensen (www.astrofoto.dk).

Observation trip




The nice Easter weather provides for great observations of Saturn and deep sky imaging from suburban West Zealand. The seeing was great for Saturn last Night. Tonight the air is more clear so deep sky imaging is planned.
