CATE Experiment Site Exploration Trip and Problems with CATE Tests

After returning home from Kona, Hawaii, on Saturday, July 8th my wife and I headed to the area where we are going to set up in preparation for the total solar eclipse on August 21, 2017.
Since it is on private property I will not divulge the actual location except to say that it is north of the tiny town of Mitchell, Oregon (population 125).



We were not prepared for the rugged beauty of the road that led to it! Wonderful!




Arriving there within minutes of the hour that the total eclipse will occur (about 10:21 am), our partner in this project greeted us and I set up the CATE equipment to prepare for an "on location, close to the actual time" imaging test.


I fully expected to complete my test within an hour but that was not to be. I just could not get polar alignment, even though I was quite sure I was near it. After nearly 2 hours of frustration, I gave up, took a few images and packed up the equipment.

My problem: The turf was soft and though I had initially leveled the tripod, when I added the counter-weight, the heavy telescope, and all the needed equipment... the leg points of the tripod were steadily but slowly sinking into the ground! AAAARRRGGH !

The solution for future reference: bring along some 12"x12"x 2" concrete stepping blocks to put under the tripod legs which will spread out the weight and prevent that "sinking feeling"!

On our return we encountered some old cars on a tour in the area! Fun!

    

Stopping in for late lunch in Mitchell we had some great burgers at the "Little Pine Cafe."
Great burgers... and even my wife said so ! ...not to mention the fries... I loved'em ! The staff was helpful and willing to talk so we pushed the conversation to the fact that Mitchell is being touted as a "great place to view the eclipse from!" They were like "Great... we moved to Mitchell to get away from the crowds! LOL!"

There we found this informational card about the total eclipse (Mitchell is very near the center of the path of the shadow). Give it a read!


It is uncertain that this cafe will be open the day of the eclipse as some are saying that upwards of 50,000 may try to use Mitchell as their viewing point. This cafe, not to mention to whole town, can barely handle a couple of hundred people (insufficient parking, toilets, groceries, etc). Good luck if you try coming here!

Hunger satisfied, we headed next door to the Wheeler County Trading Company store.

They had eclipse t-shirts for sale... we had to get ours before the selfish people got theirs! LOL !



The high school football field was going to be my initial site for the CATE project but I was told that helicopter special services (sheriff, air life, military, etc.) had commandeered it. But it turns out that the high school is renting space on that football field... for a price... and a refundable deposit fee... can you say: $7,000 deposit? No that is NOT a typo! Don't think there will be many takers...

Having had a good laugh on that we were ready for some iced mochas. Having spied this one and only espresso booth ( Route 26 Espresso )just west of Mitchell we had to stop in.

Wide awake and cooled off (it was well into the 90's now) we headed home to La Pine...
...but not before stopping in at the Painted Hills unit of the John Day Fossil National Monument parks.


I checked with the the park rangers and found out that I still could not stay overnight there due to park regulations. Just as well, 50,000 people are likely to descend on this location as it is smack-dab on the center line of the eclipse... this little, itty bitty day-time only park with a small two lane road leading to it!

If you ever get a chance, take the time and see this little gem in the high desert of Oregon... just not on eclipse weekend!

Here's a sample!

Ok, here's the thing: The skies were clear and the Sun directly behind me in this shot which will mean that the lighting is "flat". My plan: Image the total solar eclipse from my private location and photoshop the blue sky out of it. Then replace the sky with the dark sky with the Sun in totality from my location and put it it over the Painted Hills photo (since few will be able to do that in reality I feel justified in giving it a try!)



The national park system is advertising their places in the path of the eclipse with these awesome posters:

They even have a card stock poster that has safety solar glasses on top!


Upon arrival back at home, I immediately ran a test CATE imaging session with three concrete stepping stones I had already under each leg of the tripod on grass:

...and BINGO! My "sinking" (aka stinking) problem was solved! I notified my fellow CATE observers via Facebook of this "discovery" and it was met with a number of "Likes" and "Thanks for the idea!"

CATE Experiment Project Practice #5

After noticing (thanks to Joe Earp) that I had clamped down the equatorial head on the tripod too tightly (which resulted in an inability to adjust the AZ on the EQ head smoothly and finely) I now am much more careful about how much torque I secure the EQ head to the tripod.

The result is that I was able to get polar aligned in the daytime much quicker and with greater success in tracking the Sun (for the August 21, 2017 eclipse) than ever before, keeping it within the required 15 pixel maximum drift.

This first image is an HDR image created by the SolarEclipse app that CATE provided. Yes, it is over exposed but then the settings are preset by CATE for the actual totality.

This next image has been post-processed with Irfanview by increasing the gamma and adjusting the contrast and brightness a little... it helps bring out the Sunspot group 2661:

This final image is just a shot of the Sunspot group 2661 cropped and sepia toned for effect:

Practice, practice, practice!

Sharing the Sunflower Galaxy M63 with Friends

Last night was the third night in a row to be in the obs... quite a record as of late!
We have had the pleasure of having some friends visit the past week and do last night I took them out to the obs and we did some star-gazing.
Since I can count on my Meade LX200GPS and my old XP laptop with the Meade AstroStar Suite software to work together accurately, we did some quickie astrophotography. The evening's favorite was the Sunflower Galaxy in Canes Venatici.
We took about 12 images at ISO 6400 with the average exposure time of 35 seconds with the LX200GPS with the Meade focal reducer. The camera was a Canon T2i operated by the Canon EOS utility. The focus was a bit soft, but I was just trying to give them an idea of what I do in the obs.

This is a cropped view:
Sunflower Galaxy aka M63

Here is the full frame image. As you can see it was off-centered. Again this was just a quick demo. I will return to it later and give it my full attention.

Testing, Testing... Meade LX200GPS 8" controlled with PC software

Well, at long last, the skies have pretty much cleared (as it ought to be in late May) giving me more opportunities (which have been precious little since the first of November 2016) to get into the observatory (hence, "obs") and practice with the Meade 8" LX200GPS upon its equatorial wedge mount AND with the Meade Autostar software running on a old Dell laptop (with a serial port) using Windows XP (which I keep independent from the internet for security reasons).

Having lined up the scope on the equatorial wedge to be fairly true to the north celestial pole (not the "Pole Star" Polaris because it is close to but not at the actual reference point on the starry background that the sky appears to rotate about) I proceeded to start up the scope and then the laptop with the Autostar software, connect the two via the needed cable, sent the telescope to a known star, centered it with the hand controller (which is, for some reason acting up as of late) then confirmed the star in the software.

From there... it was smooth (star) sailing!

I used the software to point the telescope to desired objects, and with the focal reducer in place, every (and I mean EVERY) object was in the field of view with my 40mm eyepiece!

AWESOME!

In just a few minutes I have viewed dozens of galaxies, star clusters and nebula.
Given that I was only out to test the setup and had accomplished that, I decided to do a little astrophotography.

And once again, with my Canon T2i camera body attached to the telescope and the focal reducer EVERY object I desired was in the field of view!

DOUBLY AWESOME!

Here are some samples.
NOTE: I was not trying for any kind of pro shots, just "quickies" as I verified that the scope and software were working well together. As a result the images have a lot of "grain" in them.
Most were taken at ISO 3200 and for 30 second exposures.
But I submit them for you viewing pleasure all the same! All are presented "full frame" (no cropping)

Two galaxies from the "Leo Triplet": M66 and M65

The Sombero Galaxy (M104)

(I forgot to log the info on this one, opps)

(and I forgot to log the info on this one, too... hey, I was just glad,
ok, surprised that it was there at all !)

M64 "The Black Eye Galaxy" 
(yes, that is what is referred to as!)

M13 The Great Globular Cluster in the constellation Hercules

M92

M57  The Ring Nebula in Lyra

M52 A loose cluster of stars

M101 The Pinwheel Galaxy
(near the handle of the "Big Dipper" aka Ursa Major
aka the Big Bear, etc)

M51 The Whirlpool Galaxy

I am looking forward to more clear nights and more practice! Stay tuned!

The Citizen C.A.T.E. Project and First Light with Daystar telescope on The Sun

THE CITIZEN C.A.T.E. EXPERIMENT:
I am a primary participant in the Citizen C.A.T.E. (Continental-America Telescopic Eclipse) Experiment.

This n attempt to image the inner corona of the Sun during the August 21, 2017 solar eclipse. Typically scientists have only 2 to 3 minutes to image (video in particular) this portion of the Sun during an eclipse. The C.A.T.E. project aims to establish over 60 sites spread across the U.S.A. (from Oregon to South Carolina) Here is a map showing the path over Oregon:


At set distances apart, with identical equipment, to HDR (high dynamic range) video the eclipse at totality, like this image:


The video files will be sent to Matt Penn at the National Solar Observatory (NSO) after the event where they will be stitched together to (hopefully) produce up to 90 minutes of video totality for scientists to study.

MY INVOLVEMENT:
I first heard about this project in the January 2016 edition of Sky and Telescope magazine.

Being an amateur astronomer and wanting to do something "significant" scientifically, this intrigued me and I "signed up" immediately. I had the opportunity to be a 'state coordinator' but my schedule is busier than I could handle so I deferred to a fellow Oregonian who is retired, Mike Conley of Salem, Oregon, who had done an excellent job in helping the project.

MY SITE #5 - MITCHELL, OREGON:
My site for this project is outside the little village of Mitchell, Oregon which is on the eastern side of the state. I had hoped to setup on the grounds of the Painted Hills (part of the John Day Fossil Beds National Monuments.

But was informed by the ranger there that they are expecting untold 10's of thousands of people on that weekend because of the eclipse! A little two lane road and no parking... YIKES!

So I went to Mitchell, Oregon last August, 2016 to see if I could setup there.

As you can see, it is just a wide spot in the road, so to speak. But the only over-night places to stay were already booked... over a year in advance! Mitchell is expecting 10's of thousands as well which is going to be problematic again for I doubt it has even 50 places to park a car! Food, water, toilets for thousands... HA! Good luck on that, you who are thinking "This is the place to be!"
And the high school football field had been commandeered by emergency services (sheriff, paramedics, fire fighting government agencies, etc) as a helipad !

So I have found (hopefully) private property (location of which I will NOT disclose for obvious reasons) on which to accomplish this task.


THE EQUIPMENT:
The equipment for this project consists of, in short, a Daystar APO 80mm telescope on a Celestron CG4 mount with a Point Grey 5 megapixel b&w camera and a solar filter (more precise listing below).
No, that is not me in the photo but others being trained for this experiment.

Some of these pieces of equipment have been donated by various manufacturers and the rest has been financially supported by organizations like the National Science Foundation, NASA, Mathworks, Celestron (just to name a few) and as well as individuals who are purchasing their own equipment.

TRAINING:
Since the aim is to get video data worthy of science the C.A.T.E. Experiment (Continental-America Telescopic Eclipse) there is a need for quality training which is where the project is at the present time. Having received the equipment a couple of week ago, we are to do what we can to practice on the Sun and on the crescent Moon, working on field alignment, focus and data capturing.

My most recent PRACTICE:
As I have had little clear skies since receiving the equipment I have had little chance to practice until yesterday. Under partly cloudy skies (which even then were uncooperative) I was able to finally get the Sun in the clear to produce the following images. My goal was to image the tiny sunspot near the edge of the solar disk. After post-processing (sharpening, contrast and brightness, and sepia for effect) this is what I came up with (the second image is a cropped view).


And here is a shot of the Moon with the equipment (after post-processing)
