From 27th June to 6th July 2008 we made a long planned trip to Tenerife. Between us we took about 116kg of hand and hold luggage, the main equipment consisting of: Donal: Takahashi FSQ106ED on an EQ6 mount with EQMOD; SBIG STL 6303 camera with internal filter wheel and Truetech external filter wheel. John: Pentax 105SDHF on an HEQ5 mount; SBIG ST10XME camera with CFW10 filter wheel and AO8 active optics. We stayed at the Parador Hotel, which is a comfortable 4 star hotel and is situated in the Mount Teide National Park. The hotel is marked by the red dot on this satellite image here. As you can see, it's inside the caldera of the volcano. We were concerned about the height of the horizons in various directions before we arrived, but in practice they were not a problem. The small peak to the south east is not a major obstruction, and the horizon due south is only at an elevation of 6 degrees. Mount Teide itself is also sufficiently far away not to cause any problems. We had spoken to several people who had been there before and some told us of quite severe light pollution and others said there was none. Just in case we had to move around to minimise the effects of any pollution we took all equipment necessary to operate entirely off batteries, planning to buy some marine batteries out there if necessary. In the event we found the skies at the Parador to be extremely dark and we did all our imaging from the back of the hotel. We could frequently see stars right down to the horizon,including theta Indi at declination -53 degrees. Jupiter was near opposition at the time, and it was so bright that it projected a shadow of an arm held a couple of feet in front of a door. We could also easily see to walk around the hotel garden illuminated only by starlight. The observing site, which is 7060 feet asl, is behind the swimming pool and is shown by a red dot on this image of the hotel. At this height you are above the low lying cloud that often envelops the island. Occasionally you encounter 'La Calima' which is a hot cloud of dust and sand blown over from the Sahara. We experienced the tail end of this for the first two days, but even then the night sky was impressively clear and dark. For the remaining seven nights we had perfectly clear conditions. Between us we collected approximately 80 hours of imaging data. The seeing was never very good, varying from 3.2 arcseconds FWHM on 3 minute exposures to about 6 arcseconds at times. As we were using only 4" telescopes this wasn't critical to us, but I would like to return with a larger scope to explore this. I think that the heat absorbed by the volcanic terrain and reradiated at night is the culprit. The picture on the front page of this site shows the view as seen by the naked eye looking south, with the Milky Way and Jupiter prominent. The Milky Way was clearly visible from horizon to horizon and we could see considerable structure in it. We saw two fireballs and many smaller meteors during our stay. M31 The Andromeda Galaxy was visible to the naked eye by direct vision, as were M7 and M8 among others. Neptune was easily visible in binoculars. We tested the Limiting Visual Magnitude (LVM) by counting the number of stars visible by averted vision in the square of Pegasus and in the Keystone of Hercules. Donal, whose eyesight is better than mine, could see consistently to magnitude 6.25. On some nights we were bothered by a strong breeze which is quite common here, and on one occasion it forced us to pack up early (i.e. 03:30). On most nights we packed up about 05:00 or 05:30. COMMERCIAL: facilities for astronomers are provided by Rod Greening. These include the use of a 25" Dobsonian, pillars, an adapter for an EQ6 mount and and a large selection of tools. There are also some counterweights available. There are a number of mains outlets but you will need continental 2 pin plugs. Contact Rod at email@example.com for more information.
