Last day on the mountain.
On a less formal note, I enjoyed our visit to Summerhaven. Although my bad knee gave me problems today, the sight seeing was amazing, and I managed to find a few nice souvenirs to take back to Wisconsin and also another gift for Danielle.
I took a few exposures of NGC 1409/1410 for personal enjoyment, I look forward to processing them. I will post them as soon as I can.
I can't wait until I can get my 14 hours of sleep again...

Another Planet
As 18:00 rolled around, we began to track Jupiter again. This time, we used the larger 105 mm lens. Jupiter instantly looked better, though not too much; I think some of that had something to do with us looking at a larger image. We got some nice images; collectively we are getting better at using RegiStax courtesy of reading the entire manuel. This has allowed us to make stacked images with some more detail.
The nebula and Saturn teams were able to use the telescope since the viewing conditions were much more clear. I helped out the Saturn group since I had experience in planet imaging from Jupiter. We started off with some trouble locating Saturn, because the coordinates listed out in the computer were a bit off. After an hour or so of circling the area, we were able to find it. Saturn looks pretty cool; it looks like someone made a fake object, took a picture of it, and called it a planet. It simply looks surreal. We have yet to do much with imaging Saturn, but they should look pretty cool.

Complain blog is full of complaints.
A plague o'er both their houses! Their, of course, being altitude and snow. As I mentioned in the comments of Day 4's blog, I was rather hurried to finish it before the hike. I must say, I succeeded, but the hike ultimately destroyed me. If it were lower atmosphere, or if the snowdrifts didn't range from ankle to (once) knee deep, then I would have been in a much better mood at the end. But these are a minor price to pay for the absoultely amazing pictures I snapped at the top of mount Biggalow. We could see, according to Arion, 100 plus miles with surprising clarity. I am, once again, completely flabbergasted by the quality of the air up here. If only t'wasn't so thin..
But I am done complaining. [Note: This is a bold-face lie] A gallon of water and some pop-tarts later, I felt much better, and returned to the observatory to prepare for Jupiter imaging. Through a therapeutic chain of events, I ended up learning how to operate Registax, with limited (read: limit as x->0) success. I was able to create a semi-decent picture, but I'm too ashamed of it to post here. But I'm glad I've had the practice; it will certainly help when I start working with Saturn imaging. Let's hope this extensive tutorial of Registax will help!
Time: 6:40
And it did, at least in some ways. Using the tutorial, I've created a series of reference points, and from that I hope to get a much much much much much much clearer image. Unfortunately, in the time it took Registax to completely work before, it has completed... 12% of the first step. The time loss may very well be offset, nay! I dare say it will DEFINATELY be offset by the sheer level of clarity that this new method will create. I will make a gentlemanly bet with anyone who disagrees! Except Zach, who as already done this with a different set of data.
Time: 7:00
It was of... limited success. The image was resoundingly mediocre, and only marginally better quality than the original (the one created by using the most basic settings of Registax.) I shall try once more with a different set of reference points, but seeing as how I have more than enough time to experiment around with this, I can spare the time sink this method creates. At this point, it's just a matter of trial and error until I figure out if this method is beneficial enough to warrent it.
Time: 7:45
I was a fool! My greed for scientific advancement has created a beast that cannot be contained! Registax has taken on a life of it's own, and is now terrorizing the countryside! Luckily, me and a band of adequately trained students were able to contain, and with skillful use of task manager, the threat was eliminated.
Translation: I set Registax to work, and left to use the bathroom. When I got back, it had frozen up, and I had to hard crash my computer. At least I got a great imag- oh wait, no, it too was mediocre.
Time: 8:30
All efforts to get Registax to perform at ahigher level have been unsuccessful. Frustration has mounted, as each new step I take serves only to make the images worse. I am setting it asside for a moment and allowing myself a blissful reprieve. With that, I set out for the dorm with a few others; a change of scenery to stir the creative juices - to grant me the keystone, NAY, the rossetta's stone to understanding this complex monstrosity that is Registax!!
Time: 10:45
Fail. Trial 2, fail. 3, fail. 4-fail. Trial... trial 27 fail. Trial 28 fail! Every picture comes out blurry! Even the one that I placed umpteen dozen points to compare against, I got a blurry picture. This particular one had black splotches, uneven texture, and burning frustration. At least tonight is nearly over.. Oh wait, no. It's going on 11. Saturn team doesn't even start for another 4 hours. I find myself becoming rather discouraged...
Time: 12:00
An hours rest, and a new days' determination. I woke up at midnight exactly to a large plate of spaghetti with meatballs and red sauce. We somehow managed to forget parmesean cheese, but it was still fantastic. I'm finishing up another Registax; t'was running whilst I slept. Initial observations lead me to believe it too is goin to be trash. We will find out when it finishes stacking.
Time: 12:30
Success! The dishes were a success! What? Registax? No, the image was even blurrier than normal. I know! I thought I had it that time too. I really, truly, completely believed this image would be better than mediocre! Sarcasm? Never, I say! I am appalled that you'd suggest such a thing! I say good day, sir. I say, Good DAY sir!
Time: 6:00
Another nap, and I was nice and refreshed for Saturn imaging. We aligned the telescope, spotted Saturn beautifully in the view finder, and were ecstatic to see... absolutely nothing. Blank screen. 3:30 am, using the given catalog values, we got a wonderful view of open space. It took until 4:15, with some help from Arion doing voodoo-mirror aligning in the control room, we found Saturn. A focus was ascertained, and then we took 10 short exposures over a range of focus' to find the range for focus'. A series of 5 more slightly longer exposures cemented a small range of ideal focus values. As the day wrapped up, we took four 2000 frame exposures, which shall be what we analyze. A shame we didn't get anything on day 1, this promises to yield at least decent images.

Up on the Mountain
Day 4
A great and productive night!!!
We managed to process pictures of NGC 2022 using the oxygen three filters before closing down. They revealed what we suspected to exist: an outer most shell of gas exceptionally farther from the white dwarf than any visual photo on the internet showed. We also managed to get higher resolution photos of Jupiter which revealed an odd storm system not present yesterday. Our first pictures of Saturn have been taken and are waiting to be processed. Saturn gave us trouble once again; we had to manually find it since the database did not give us the correct coordinates. It's almost as.if Saturn is living up to it's pagan name sake....
Catchin up...
We’ve been posting on this blog for days, and I realized that anyone reading our posts probably has no idea what it is we’re working with. This is the giant 61” Kuiper Reflector Telescope. The 61” refers to the diameter of the huge paraboloid mirror housed near those large orange supports, facing skyward. The telescope itself tilts up and down, and the orange support frame rotates to sweep the sky. That dome in the background rotates to follow the telescope as it slowly tracks objects across the sky.
There is no way to describe how elegant and massive this thing is. Standing underneath it on the work platform is humbling. The weight of all 5 tons is balanced so exactly that the motors to turn it are no more powerful than a lawnmower, and have such precision that a laser fixed to the end could trace the text of a billboard on the moon.
I didn’t post yesterday as my laptop has become a bit of a town bicycle in terms of capturing video and such. The Internet is constantly monopolized. This reminds me NOT of how “wired in” we are to media, but rather how good humans have become at using the tools available to us. Many problems have come and gone quickly while on this trip thanks to the resourcefulness of a young Carthaginian. Speaking of solving problems, tonight marked some VERY good footage of Jupiter. Zach has posted some of those photos already, so go check his profie. Coty and I cooked up a delicious Spaghetti and meatball dinner complete with garlic bread and dead scorpion. There were compliments all around.
Saturn hasn’t risen yet, so while I blog I have only to play the waiting game. Preliminary ring photos to come soon!
Night 2 - Exhausted and Crabby
After an afternoon of preparations, we changed our web cam attachment to the 105mm lens and began imaging Jupiter for the second night. We started by finding our focus value by taking 5 second videos from 17900 to 17800 dropping ten units each time. After stacking these images it was determines the optimal focus value was between 17840 and 17870. We then took about 10 videos ranging from 1800 frames to 2500 frames. This took us about 2 hours. Once we had all of our videos it was time to begin stacking frames in an attempt to get one sharp picture, this tested my patience. I read through manuals, looked at online tutorials, and played with Registax for a couple of hours and came up with a pretty good image. I then proceeded to save an empty file somehow and lost the image. #@$%!!!! In lieu of this loss I doubled my research efforts and started over with the 17855 focus video. A good focus combined with lots of trial and error yielded my personal best image yet, here it is:
With my interest in Jupiter exhausted, I took 3 exposures of the Ghost of Jupiter Planetary Nebula for personal studies. I am excited to develop these and see how it turns out. About five of us got to pick personal stellar objects to image tonight, once all of those were done we began preliminary imaging on Saturn. As I was working on Jupiter Image compiling I did not get to see much of Saturn but I am excited to see the others results.
On an interesting side note: while Coty, Ian, and I were cooking dinner we were surprised by a little friend hiding in our spaghetti pot!
(Its a scorpion, I am breaking the story to the rest of our classmates on this blog... They will have no idea until they read this!)
p.s. tempers are getting short due to lack of sleep, hopefully nobody does any lasting damage by speaking before they think.
A rough night of imaging :(
I’ve been working with the Jupiter group a lot, and tonight yielded less impressive photos than the first two nights. We switched to the 55 mm lens for the sake of fitting Saturn’s rings completely in the frame later in the night. This cut the image size by about half for Jupiter, and changed the requirements for the levels. Because we have to use the lowest exposure time possible to freeze out turbulence, the images turned out darker than last night. The contrast is worse, fewer details are visible, theres some visible bias noise, and Registax is having a hard time aligning features. I don’t know whats going on, but hopefully my group (Saturn) will have better luck getting data.
UPDATE. Saturn showed up just about as clear as on the 105mm lens, but the seeing was noticeably worse. Registax will be the final judge of quality in that regard. No images from me tonight, the atmosphere has me in a bad mood. I need a hug and a comfy bed :(
