The observatory holds three telescopes on one custom made mount:
- Cassegrain Relay 400mm f/6.5 = 18' x 12' (arcminutes)
- R120S 120mm f/6.6 = 1.28º x 0.96º (arcdegrees)
- R80 80mm f/6.0 = 2.65º x 1.76º (arcdegrees)
While the exposure was running we mounted an old Canon camera to the second telescope and did another photo of the Sombrero galaxy. It was just interesting to see the difference in seeing and magnification (the result can be found below). One thing I found very interesting was the fact that re-focusing was possible even while exposing an image. If I would do that at home the frame would have been ruined. However, due to the very stable construction no blurring occurred.
After we collected some frames of the Sombrero galaxy we decided to try some other objects with just shorter exposure time. For example we tried M3, M95 and the huge Omega Centauri cluster which is not visible from Germany at all. Those results can also be found below.
The hours passed very quickly and after 2o'clock we decided to finish our observations due to the long drive home. I copied everything to an USB stick so process the raw data later. Some of the results can be found below.
Conclusion: If you are once on La Palma and you are interested in taking photos of the night sky with a quite good telescope you should pass by at the Tacande Observatory. Last updated: April 8, 2017 at 9:48 am
