Expedition Group Arrive at La Palma

Expedition members Alan Lorrain and Dave Shave-Wall have arrived for a visit to La Palma, with the express aim of checking out the North West quadrant of the island for suitability of future BASEG trips.

After arriving at the airport on La Palma around 12pm, think very early flight, the two packed their multiple suitcases into a Seat Leon estate that easily took 5 large suitcases and 4 smaller laptop, rucksack and wheelie bags.

The drive took us past Lidl just North West of the airport for a quick stop, as this was a self catering trip and then heading further West, through the long tunnel and then North through the multiple winding roads. The final piece of the drive to the villa El Sitio at the Garafia complex of 5 or so villas was fairly off road with the car just making it up the steep winding drive. 2 hours had past not including the Lidl stop so it is a fair trek from the airport. The height at the villa is 4,335 ft give or take the error from GPS and puts you above the clouds, at least on arrival.

The accommodation, 1 bedroom and a lounge with a sofa bed are adequate for the weeks stay, the bathroom, eating area, kitchen and patio areas are lovely, there is a shared pool, your own sauna and various paths around the property.

There is also a 10″ Skywatcher Dobsonian telescope with various eyepieces in the small building next to the pool free to use. An extension cable was provided and Christian, the manager who works for Tobias the owner was more than helpful in explaining how to turn off various lights that would come on during the night.

So after a long day, food was in order whilst setting up the equipment for the first nights viewing was going on.

Tenerife9 2018 Session Ends Early – Saharan Dust Stops Play

The group has had to bring the session to an early close due to the Saharan dust levels wiping out the sky quality. Known as the Calima, hot winds from the East bring Saharan dust across to Tenerife which destroys the sky quality needed for deep sky imaging.

We monitored the SONG (Stellar Observations Network Group) weather page throughout the week to assess our chances at clear sky imaging. When the red level is breached then the resident telescopes at Teide close their domes. For our purposes we were looking for dust levels around 0.001 which is below the yellow line.

Before the Calima arrived the SQM was measured to be around 21.68 mag/arc sec2 (Bortle class 4) compared to around 20.5 (Bortle class 4/5) in the UK local area. Bob’s image also shows the visible layer of Calima dust :

It was a good week for all regardless of the common issues many of us encountered that stopped initial imaging attempts but once into the groove some nice images started to appear both for the portable deep sky imagers and those using the Mons Telescope for spectroscopy and lunar/planetary imaging (Mars/Jupiter/Saturn/Neptune/Uranus).

We would like to extend our gratitude to the IAC for allowing us to the use of the Mons Telescope and the associated facilities ….. gracias amigos 🙂

New kit for upcoming trip to Tenerife

After a couple of trips to Tenerife with my Canon 5D Mkii, Canon f2.8 200mm prime lens on an AstroTrac as my main imaging kit, I’ll be adding a Takahashi FS60-CB with a flattener and an ATIK Infinity Mono camera to the mix.

Recent imaging for the dstl Project Argus has helped resolve adapter issues with the FS60 / Canon DSLR combination as it is a FS60 special and not a regular Wide EOS adapter that is required.  Live broadcasting to YouTube will also be a new possibility this trip with the ATIK Infinity camera.

 

Preparing for my first Tenerife trip

So since I don’t have a mobile setup like the veterans of the group I’m resigned to fact that I need to take most of my UK setup with me abroad. This means some serious weight to transport, so basically I have the following to pack and carry :

  • Hold bag1 (~18Kg)
    • Skywatcher NEQ6 mount
  • Hold bag2 (~18Kg)
    • Skywatcher Tripod (7Kg)
    • Counterweight (5Kg)
    • Box of accessories (~6Kg)
      • PSU, cables etc
    • Clothes …. I guess
  • Cabin bag1 (~7Kg)
    • Tak FSQ85
    • Tak focal reducer
    • Atik 460 CCD imaging camera
    • Lodestar guide camera
    • PoleMaster camera
    • Lakeside focuser control unit
    • Unihedron SQM
    • ADM Scope plate
  • Cabin bag2 (~6Kg)
    • Atik EFW2 and filters
    • Laptop & NUC
    • Various digital items (GPS, USB hard disk etc)
    • ADM mount puck and scope rings

Hopefully the scope bag will in in the overhead with it’s precious contents….don’t drop it ! The laptop bag should fit under the seat….hopefully.

I won’t be sure on the final weights until the digital handheld scales I’ve ordered arrive tomorrow.

At the moment I’m just finishing the calibration and setup of the Lakeside focuser and it’s configuration in SGPro.

Update : The digital scales arrived so now I have weights for a few items and move things around a bit –

  • Hold Bag1 = 19.3kg
  • Hold Bag2 = 22.5Kg
  • Cabin Bag1 = 8kg
  • Cabin Bag2 = 8.85Kg
