For those who have been paying attention to the sky over the past few months, you will have seen Venus crawl out of the evening twilight, and Jupiter sink towards it. These two VERY naked eye planets (both outshine even the brightest stars) are now only about 15 degrees apart (about the spread of your fingers held out at arms length), with that value set to shrink to about 3 degrees over the next 3 weeks. Get the popcorn is ‘cos its gonna be a fantastic show!
The ballet is highlighted in the sequence below.
Venus Jupiter conjunction of 2012 (click to enlarge)
A) t= 0. Jupiter and Venus hang in the evening sky. Venus, by far the brighter of the two lies below Jupiter, and the pair are separated by about 15 degrees. For reference, the Moon and Sun are about half a degree in diameter, and your outstretched fingers at arms length are about 15 degrees in angular size.
B) t= 5days. The moons orbit takes it out of the solar glare and by the 26th it resides between Venus and Jupiter. This will be a spectacular sight for those who get to see it, with the 2nd, 3rd and 4th brightest objects so close together in the sky. The angular distance between the two planets has now closed to about 10 degrees. Most of this apparent motion of Jupiter is due to the Earth moving around the Sun, while with Venus, about half of the apparent motion comes from this planet orbiting the Sun.
C) t~21 days. The Venus, Jupiter conjunction of 2012. The two most spectacularly bright planets appear at their closest (~3 degrees).
D) t~33days. The Moon has now made a complete orbit since it last visited these planets. When it last did, Jupiter was the higher, and Venus the lower. The second time the moon visits these planets the order is reversed! Venus the beguiling bright is now the higher of the two objects! The objects are again separated by about 10 degrees.

When I staggered out of the wilderness last night, in the dark, exhausted, without any food, or drinkable water and with a broken plane, I had only one thought. What a fantastic couple of days!
Panorama looking down on Jack Ass Pass near the Cirque of the Towers
The story starts with wanting to go see the ‘Cirque of the Towers’, one of the most beautiful places on Earth. However I wanted to get some video of it from the air! Now the story of my failure is long, and surprising short of predators, although, for some unexplained reason it has a llama in it!
Now getting into the Cirque is a bit of a chore in that you have to drive some 30 or so miles down dirt roads (which can require a LOT of attention if you are in a low clearance 2 wheel drive car). However once you get to the Big Sandy trailhead, it gets interesting! Getting to the Cirque is a hard days hike, but easier as a 2 day trip. Its about 8 miles in, and about 2-3000 feet of ascent. However I was packing in a plane and all the kit to go with it too! Not to mention a tent, enough to stop me freezing in the expected well below freezing temperatures, and enough emergency kit that I could make it back to the car in a tight pinch.
INTO THE CIRQUE!
The first thing I noticed was:- no mosquitoes! That was such a blessing. Previously when I’ve been here they make your life a torment in that whenever you stop, great clouds of them descend on you, and bug spray and nets or not you get peppered with bites. Same goes for when you pitch the tent, you basically have to throw up the tent and get in it asap just to escape from the bugs. This time, NOTHING, nada, not even a hint of a mosquito. That made the walk through the dry piney forests of Big Sandy incredible pleasant, but in the back of my mind I was fully aware that the reason there were no mosquitoes was that a hard frost had killed them all. It was likely to be cold that night.
I left the car at 2pm, not out of any great plan, I just knew that was plenty of time to set a ‘base camp’ of sorts. There are also significant wildcards about heading out this time of year. Thankfully it’s too late for nasty thunderstorms, but snow is more likely to be the real hazard. First sign of bad weather and I would have to abort. No way was I prepared for harsh weather, and even getting back to the car would only be half the battle. However the cirrus cloud which I wasn’t quite sure if it was a front coming in (in which case I would be screwed) or was just some weather created by the mountains, burned off, and the rest of the day was as beautiful, pleasantly ambiently warm as a man under a deep blue sky could hope for.
The place was near deserted (the crowds of summer gone!), and I only passed maybe 5 people heading up to Big Sandy lake. Then came the first choice, to head up to Temple or into the Cirque? (right or left at Big Sandy lake?) I opted for the Temple, a giant triangular looking granite monolith. Merely to sand under Temple is an intimidating experience. I pitched camp in the last trees under Haystack. In this case it primarily wasn’t for fear of lightning, but in the full knowledge that it would be several degrees warmer in the trees, and given that I really wasn’t sure how my sleeping bag (‘rated’ to below freezing) would actually perform. As it turns out it did just fine, however my pillow was a pair of boots with a pair of pant (trousers) and fleece thrown over the top, prove more troublesome in getting a good nights sleep. Also there is the latent fear of the night predators. I’d hoisted the food into a tree, but you know that you are ALONE. There is no help. That sort of exposure sharpens the mind, and gives on a very light sleep. Was up about sunrise, although no direct light filtered down into the valley.

After a breakfast of ‘instant noodles’ I headed up towards the cirque of Temple, taking only the plane and some food. It was a pathless bushwhack, but not difficult. The sharp spike of Steeple rising steeply over the lake making for some excellent views before coming into the presence of Temple. And YES, I went to Temple on a Sunday!

I was completely alone in this cirque.
The condition for flying were as good as one could hope for up in the mountains. Scarcely a breath of wind, with giant mountain shadows littering the landscape. Bummer was the voltage regulator had fallen off the transmitter side of things on the plane, and I assumed my wiring was regularly color coded. Well anyway, I plugged in the battery, and theres this futt sound and a smell of burning electronics. I’ll wager that’s smells not graced the presence of Temple before! So that was the end of the possibility of remote video, however, I could still just record with the camera on the plane. It’s SOOO much easier to fly without the Helmet of Magnetar! Sure you can’t fly out of line of sight, but you only have to worry about flying the plane. Flight was fantastic!.
Best flight EVER!
I then decided to head up onto the unnamed mountain in the middle of the cirque (the mountain of broken planes?). By the time I had gotten up there, there was a random wind blowing up to 15 mph, but the view was phenomenal!
Random un-named mountain (Plane Destroyer Mountain?) near the Cirque of the Towers
But a 15mph wind that’s tricky. The plane is already heavy (almost 1kg) which means it has to fly faster to maintain its lift. Further I was already at almost 11000 feet which means that in order to get stable flight you need to fly faster due to the thin air. Getting into the air proved trivial. Getting it to land, that was difficult. You see I probably only had 10ft or so of uneven granite to land on. I was ontop of the mountain, to overshoot means the plane falls off the cliff on the other side. To undershoot means flying into a granite block! In the end, after several aborted attempts where the plane, due to its slower speed and the irratic wind had almost been tipped over, pretty much out of desperation, I bought the plane in ‘hot’. Sure it was fairly stable, but on ‘landing’ the camera and motor broke off. In many ways it was a relief, in that there was now no way I could do aerial video of the Cirque of the Towers (meant I didn’t have to take all this kit up to the pass). I packed up and took the short way down. Risky to be sure as I had no surety that the path wouldn’t end in an impassible cliff. Thankfully it didn’t and I saved myself about a mile of bush-whackin’ down to Temple lake and back again. On the way down, of all the bizarre and unexpected things, I found a llama with no apparent owner. WTF?
Random Llama!
It took to its heels as I approached. Dropped down to base camp by about midday, packed up and cooked what food I had left (more raman noodles!). Then the trek down to Big Sandy lake. Got to the path up the Cirque of the Towers by about 2ish. Took basically all the water, wine and food I had left, and headed up towards the cirque. I was very tired by this point, and to make matters worse, lost the trail just before the first lake and ended up in a giant boulder field. There was many a hole you could have fallen into and never been seen or heard from again! I reached an overview of Jackass Pass (my target) by 4pm, but I was a spent force. I could go no further. It was a double blessing that the plane had crashed, for there was a steady 30 mph wind gusting higher near the cirque, all but impossible to fly in. I hung around on the pass till 4:30, full in the knowledge that I would be walking out in the full dark. Going down was fast, aided by the fact that I kept the path the whole way.
Defeat at the Cirque
Got back to my pack at 5:45pm and began the weary trudge out. I was all but out of food, all but out of drinkable water. Now its true that I had both water treatment and a water pump, but was reluctant to risk using them if I could avoid it. (theres a really nasty bug in the water around here called giardiasis). By 8pm it was near full dark and I was walking on a head lamp, so tired that I could only walk for 10 or so minutes at the time. Turns out the headlamp was fantastic, as not only did it free up both hands, but periodically you could sweep the local area looking for glowing eyes! However it could only penetrate the murk for 20 or so feet, and I was ever fearful of losing the path. I eventually managed to get onto the flats near the trail head, but was lost in what turned out to be the campground. It was both a delight and a nightmare to find those park benched. I knew I was REALLY close to ‘home’ but had no clear idea which way to go. I then found a road. Again, great, but which way to go when you can only see 20 feet? Turns out it was the one way loop around the campsite, and if I had known I was probably only a couple of hundred feet from my car. I guessed good and as I came over the gentle rise, what do I find on the other side, but my ‘little blue New Yorker’! Dumped everything asap, tanked up on water and chocolate before crashing for the night, having to run the engine periodically to stave off the cold of the night freeze.
So for night time I decided to indulge in a guilty pleasure, and just drive off into the quiet forests of Oregon, and just, well, sleep! Well mostly sleep. I did leave a timelapse going of the milky way from the forests of Oregon…. Pretty!
The next morning I was up early, and spent it bumming around crater lake. When I first got the lake, it was mirror still! It’s rarely that still at crater lake (normally wind disturbs the surface, as it had does by the end of this timelapse), so I set up the camera… more pretty!
While that was going down, I got accosted by one of the GIANT VOLCANIC CHIPMUNKS that roam the area!
And boy did that 4.5mm sigma 180 degree fisheye lens earn its keep at crater lake. Y’see Crater Lake is just so big by the time you can see it, basically only a 180 degree lens will get it all in!
A keep back sign? Now that's just being a 'cliff tease'. Seriously though, these signs litter Crater Lake, which to be fair has a lot of cliffs, but does it really need all the idiot warning for people too stupid to spot poor footing and a terminal drop off?
and these ‘keep back signs’ litter the area in a way that smells of ‘frivolous lawsuit evasion’, or maybe it’s just to keep the number of Darwin Award winners from Crater Lake down.
Spent that evening on top of Mount Scott, well actually a rocky outcrop you have to climb up on near the top of Mnt Scott. But the views were amazing. Just sat there and watched the sun go down over the lake!
Thunderf00t on mnt Scott looking down on crater lake. And yes, its about a 50ft drop off that rock! Mnt Scott is the highest point in Crater Lake NP. The actual summit has a fire lookout built on it and smells of urine. However for those willing to do a little hand n foot scrambling, there are a couple of satellite summits that have amazing views.
Spent the early evening helping doing some astronomy outreach (of a sort). Skies were dark, but a little murky. Had the scope catching photons from the M101 supernova till about 2am before packing up. However Jupiter rising over the lake gave some captivating specular reflections! Left the timelpase running till about 4am, would have been longer, but I feel asleep before changing the battery. Damn my intolerance to sleep deprivation!
Next morning, a very tired Thunderf00t decided the air was still enough to take to the skies, using the helmet of doom! Here I was alternating between first person flying, and flying by direct sight. It’s really ballsy stuff in that by the plane has to be quite close (relativley) to fly by direct sight, and if you go further, you are 100% reliant on the video and RC gear working. There is also the problem that by the time the plane is so far away, that you cannot see it, the plane also cannot see you! So bascially you have to navigate by big cliffs and the sun to find your way home. The bottom line is, while the plane was almost beyond the point where you could see it to fly it, it still didn’t make it over the lake.
After that little adrenaline rush I was ready for some excitement, which came in the form of swimming in an ice-cold lake formed by a collapsed volcano!
and yeah that water looks perty and blue, its just as amazingly blue when you get your head under it! Regrettably, by the time I’d worked that out, I’d left the contraption for getting the camera underwater (a sort of ziplock bag) back in the car, 1000 ft above me on the crater rim
It’s about a total 3 hr exposure with a 11in CPC1100, using a canon 60d (iso 2500). 30s exposures, throwing away bad exposures (about 60 %) to yield this using deepskystacker (using about 50 dark frames). The arrow indicates the supernova.
Supernova in M101, August 25th 2011, about a 3 hr exposure with an 11in scope and 2500 iso on a canon D60.
Clearly an improvement of the first attempt which only included about 12 minutes of ‘sky time.’
Right, now back off to the pass to do the same thing again tonight! Me= CRAZY! :-p

I then brave the moquitoes, and yeah, there were a LOT of them, to get the scope set up.
The scope acquired data for several hours, this is thus far only processed from 6 minutes worth. I’ve also not got round to sorting the colors out which is why the new exposure appear blue compared to the old one.
Uranus is frequently overlooked and for many reasons. Firstly, lets just say its name hasn’t phonetically aged well. Secondly it’s small and faint, barely visible to the naked eye, and even the most powerful telescopes show little more than a tiny featureless grey-green disk.
Most powerful telescopes will show the five main moons of Uranus, Miranda, Ariel, Umbriel, Titania and Oberon. The innermost of these Miranda, has, if memory serves the highest cliffs in the solar system (due to being previously (presumably) smashed by an impact) and has an orbital period of about 1.5 days. That means you should be able to easily see its movement over the period of a night.
Now I had tried this previously, and had been surprised that the planets movement was comparable to the movement of its moons, but that night had been scuppered by a flat battery.
The stars in the background are fixed. The two picture of Uranus are taken a few hours apart, and while the moons (relatively close to the planet) don't move much, the planet conspicuously moves against the background stars!) (click to enlarge)
So it was that I set out with my scope on the evening of 22nd Aug 2011 to see what could be captured. I decided to head up to an observatory site that had previously seemed good up near the top of the somewhat active volcano, Lassen Peak. The site is high, almost 2 miles up, but the seeing was less than perfect (a very constant ~ 5mile an hour wind, which was probably a blessing in that it bought warmer air from somewhere, but was also a curse due to the wind chill- I was surrounded by snow fields!).
Nonetheless, at prime focus of the 11in CPC1100 with ~1000 iso and 4 second exposure on a canon 60D seemed to bring out easily at least 4 of the moons of Uranus.
After that, I just had to maintain the kit for 8 or so hour. A pain in the ass, as there were several pieces of kit that all need to work or the night would be ‘lost’. So you basically have to periodically check all the batteries on the various time lapse and tracking kit are working functionally. The bottom line is you can actually get quite a lot of sleep, but its horribly disjointed. The practical upshot of which was the next day I was wiped out to the point where I had actually planned to head up into Oregon to do something, but for the first time ever on a road trip I did something I’d never countenanced before. I stayed a night in a motel!! First time in 5 years! A motel 6 I should add! All I wanted was somewhere where I could get a shower, a bed for the night, and damn, just sit back for a moment, put my feet up, and have a glass of wine……ahhhhhh.
I was REALLY happy when I processed this, not really for what I had hoped to achieve, which was to get the motion of the moons, as while it was visible, it wasn’t that great. But what was great was the motion of the whole Uranus system against the background stars. I knew this MIGHT be visible, but I really didn’t expect it to looks as cool as it did! Now it should be said that most of the motion you see here is probably not due to the motion of Uranus, but due to the motion of the Earth. Nonetheless, its still really cool!
