  1. Still fighting DSS to stack my 46P subs, so made a time-lapse instead. 89 x 1min, taken on 27 Dec with Fuji x-T1 and Samyang 135mm. Size of frame is 2.2 x 1.7deg. Have a much better quality avi file, but that's 214MB, so need to figure out how to convert it to MP4 in better quality (for this one I used youtube ) DSCF4370avicropbright2mb.mp4
  2. This August I was lucky enough to go back to La Palma with the family for a couple of weeks. Perhaps more importantly I was able to take my cameras, and this time I hired a telescope over there rather than look at the skies wishing I had my scope with me. Same as last time we were unlucky with the weather, by La Palma standards, and several nights were lost to very thick Calima - dust laden winds blowing from the Sahara . These clog up the sky and raise the temperature quite drastically. It also severely hampered my ‘schedule’ of timelapses I wanted to get but living in the UK I can expect perhaps one night in two weeks to be clear. I can’t complain at the loss of 4-5 nights out of two weeks! Although it was frustrating to miss the Perseids again - they were on the one night it actually rained!! La Palma, perhaps surprisingly for one of the best locations for astronomy in the world, is a very cloudy island. When conditions are ‘normal’ it is usual for the inhabited parts of the island at less than 3000 ft to be frequently cloudy at night time. The cloud comes and goes but is often there and can be seen in several of my timelapses. There is an inversion later at approximately 3000ft though above which it is as clear as it’s cloudy below. So, if you can get high enough you can get above the clouds and almost guarantee starry skies. But, the same situations that give those clouds give us cloud waterfalls over the Cumbre Vieja (the ridge of hills linking the north and south of the island) and some amazing fog. I could go back to La Palma just to do timelapses of the fog/cloud! If you can get high enough it’s truly worth it. Up at altitude the skies are very steady and clear. I could see detail and texture in the Milky Way right through from beneath Scorpius/Sagittarius, right overhead and down into Cassiopeia and Perseus. The Milky Way was visible right down to the horizon and the stars were pinpoint spots of light - no twinkling, not even low on the horizon! There are various spots at the side of the road you can set up on - although be prepared for a number of cars to drive past with their lights full on! I was quite surprised at the number of cars - several of my timelapses show the observatories lit up by cars with their lights on full. Of course, arguably I was part of the problem… but then I was happy to drive around on sidelights (once I’d sorted out turning off the cars internal illumination!) I met and spoke with a surprising number of people, mostly Spanish and German. But it was frustrating whilst taking a timelapse to have people drive up and take pictures of themselves pointing a torch at the Milky Way, right in my field of view. Some of my timelapses show this despite my best efforts. I was able to take Tom up with me a couple of times (even Kate came up too one night!). I quite like being on my own at night but at altitude and with the humidity at less than 5% and the walking around often being on rocky broken volcanic surfaces it was good to have company. Of course, Tom being 10 he can see way better than me, something he was happy to point out regularly! I've put together a timelapse which I’ve called the Road to the Roque. Whether you approach the Roque from the east from Santa Cruz de la Palma or from the north west (Hoya Grande) it’s at the top of a long very switchbacked road. Driving up and down 7-8 times over the two weeks burned out the hire cars brakes - thank goodness for power steering! You can’t get to the top without going up the road - the views along the way were stunning so any timelapse I put together I wanted to include that part of the journey! The car brakes really were burned out. On the last day driving back to the airport they were noisy enough I felt it best to leave the car in second gear for the last 13km (downhill).. I hired a telescope for about a week out there from an outfit that turned out to be just 10 minutes up the road ( http://athos.org ) A German setup (the guy I spoke to, Jan, spoke perfect English!) which has to be the kind of place I’d happily just move to (just as soon as that lottery win comes in). They have a place with several small houses for accommodation, observing platforms, observatories, plenty of kit and are in a truly dark spot. Absolute Paradise! They kindly gave me a guided tour (they took care I didn’t wake up some of the astronomers that had been up all night) but the place was great. I have started siphoning off money from my joint account… (luckily Kate doesn’t go on SGL!). I hired an Evolution 6 with Starsense. My rationale was to have something I could carry around easily and for it to be smaller than my main scope at home and something I haven’t used before. It worked out perfectly, the little 6 inch was giving me much better views than my 10” Newt does a home and many an hour was spent looking at Mars, Saturn, Jupiter and Venus and looking at objects in the lower reaches of the Milky Way that we can’t normally see from the UK! The starsense was cool - level, aim north, hit a button… and it just worked! I could blether on for hours but won’t - here’s a link to the time-lapse I’ve done. Its missing some stuff I wanted to get but some stuff worked better than I’d expected so I can’t complain. A couple of the timelapses were done in strong dusty winds, in one of them I spent an hour hunched over the camera on it’s tripod holding a large black cloth as a shield for me and the camera from virtually gale force winds. Amazingly that one worked well although my shoulders weren’t so happy! Getting lost on the path on the way back down to the car was a bit hairy (the caldera was 20 ft to my right) but a bit of judicious Maps usage on my phone (most of the island provides at least 3G) enabled me to figure out that the all but invisible path I needed was just a few feet back from where I was… Finally, all else aside, I can’t overstate what having dark skies does. I live in a dark part of Devon and am grateful for that but the skies there were obscenely dark. The little villa we were staying in near Puntagorda on the north west of the island - you could walk literally straight out of the lit kitchen onto a patio and bang, there was the Milky Way, better than we even see it here, visible clearly in completely un dark adapted eyes… five minutes later and it’s enough to make you think… I could work from here you know, no need to go back to the UK…. I’ve started blethering again. Here’s the timelapse, I hope you enjoy it!

    Moonlit Caldera

    From the album: Imaging Challenge #15 - The Milky Way - Now Closed

    A 25 second exposure from a time-lapse taken over the cloud filled Caldera de Taburiente in La Palma in the Canary Islands. Mars is the red object to the left of the Milky Way. Saturn is in there too but is lost amongst the milky way. The bright lights hidden under the clouds are from the towns of Los Llanos and Tazacorte only about 7-8 miles away as the crow flies but about 90 minutes away by car! 25 sec at f/1.8, 14mm Sigma lens, ISO 3200, Canon 6D. The scene was illuminated by a crescent moon beyond the right of the image.

    La Palma Lighthouse

    Wasn't sure where to post this but I'm going to the south west of La Palma in a few months and noticed on the dark sky maps that it's pretty dark (understatement) near the lighthouse at the southern tip of the island, as dark as the north where the observatory is sited. Anyone been there ?

    From the album: La Palma

    The Gran Telescopio Canarias on the Roque de Los Muchachos with the Milky Way behind. The foreground is illuminated by a 4 day old crescent moon off to the right. Dust from the Sahara is present which is illuminated by light pollution from towns to the west of La Palma approx 15km away.

  6. From the album: La Palma

    A crescent moon setting over La Palma from the north facing side of the Roque de Los Muchachos. The astronomers accommodation is visible to the far right of the picture and clouds down near sea level (about 6000ft lower) reflect the moonlight. The Milky Way is coming into view on the left of the picture. A single picture can't give you sound (yet) but at this spot the sound of the cicada's was almost deafening unlike a few hundred yards the other way in the caldera whee the sound of the mosquitos is almost deafening... 20 seconds through a Canon 6D, 14mm Samyang lens at f/2.8, ISO1600

  7. I was lucky enough to spend two weeks on La Palma in the Canary Islands this August with my family. Whilst we were unlucky with the weather in the first week (it rained, was cloudy and the air was very dusty blowing across from the Sahara) the second week was much better with some stunning skies and views to be seen. My original plans for various time-lapses was thrown out of sync (not entirely unusual for any UK based astronomer) and I ended up with just 4-5 nights to capture what really needed about 8-9. Whilst there's a lot I couldn't do, I was able to get a fair amount including two nights up in the vicinity of the Observatories on the Roque de Los Muchachos. Some of La Palma's most striking views involve clouds - the Caldera de Taburiente (a stunning sight from wherever you look) regularly fills up with clouds looking like a bubbling cauldron and sometimes clouds cascade over the Cumbre Nueva - a mountain ridge across the middle of the island. This ridge often holds back those clouds - it's not unusual to drive from the sunny west side through a tunnel onto the east side where it's cloudy, raining and much cooler. I was able to capture a quick time-lapse of clouds cascading over the Cumber Nueva from the Mirador El Time whilst enjoying a coffee at the cafe there. It doesn't get much better than that!! The earlier time-lapses were captured in the vicinity of the villa we stayed in, El Sitio in Fagundo, Puntagorda. Some of the later ones were captured at the 'Hacienda La Palma' from about 4500ft (1370m) altitude and some from in or around the Roque de Los Muchachos. The skies at Hacienda La Palma and up at the Roque were stunning with virtually no light pollution. Even lower areas had skies far better than usually seen in the UK. Phenomenon such as the Zodiacal light (where dust particles along the plane of the ecliptic are illuminated) were very obvious and whereas in the UK the predominant colour I have to process out of images taken is orange from light pollution, in La Palma the skies' natural green glow was very obvious in my images. That said, La Palma is a cloudy island - most of the clear nights in my second week there were due to my being at higher altitude. It was a common sight to see overcast skies hundred of metres below but not a cloud above. This video is a compilation of some of the time-lapses I did get. I made plenty of mistakes on these time-lapses, not least I should perhaps have gone when there was more moonlight to light up the ground a bit, a little different from the approach to astroimaging we're more used to.. all the more reason to go back and try them again of course Hope you enjoy.. don't forget to make sure the HD button is on when watching and turn the sound up, or down depending on preference Kate and the kids are visible in a couple of spots, I deliberately left them in - but I removed the selfie taken at the top of the Roque de Los Muchachos just after sunrise one morning as I looked about 90!!! Four sleepless nights hadn't done me any favours! Equipment: I used a Canon 6D, modded Canon 650D, 24-105mm Sigma lens, 14mm f/2.8 Samyang Lens and a 8mm Samyang Fisheye. Tracking and panning were done using a Vixen Polarie with a time-lapse adaptor. https://vimeo.com/139641078

  9. I didn't realise there was data on this in the School's Observatory archive until I posted a question on the forum. It turns out that you have to have a teacher or student account as the data is in the GCSE Astronomy section. When I looked I found a lot of images, this is just 120 seconds of R, G, And B. I had to do a gradient removal and a DDP followed by a couple of histogram stretches, ending with a lw-pass filter to get rid of the noise. The rest of the images in the archive are just 60 and 90 sec which might be OK for preserving the cores. There's more structure in the image, including the tidal tail but it's very noisy.

    Sunset

    From the album: La Palma

    A sunset shot... we had several fantastic sunsets in La Palma, mostly missed by me setting up other kit or eating/driving up the mountain. If I ever get the chance to go again I will definitely be concentrating on some sunrise/sunset photos!!
