I) Taking your First Image: AddTelescope Command
In this 1:12 video, Chris explains the journey of the code from the moment you hit submit through the movement of the telescope:
****************************
You have been learning about writing Quorum code with the goal of making an image request through the Skynet network of telescopes. The Quorum code you have learned will help in your understanding of how the image processing software, Afterglow Access, works behind the scenes. For the image request, the Quorum language and libraries talk to the Skynet servers through an API (Application Programming Interface). At this point in time, the Skynet server has been updated, but the Quorum library and commands which control the interactions have not been. Therefore, our image requests will be made directly via Skynet. Note you still will be using Quorum to understand the inner workings of Afterglow Access in Section 2.
The instructions and links provided below will guide you in the process of requesting images through Skynet. The first set of instructions uses a Sky Viewer which is visual in nature, and includes a video (or the video transcript, whichever you prefer) with screenshots. For known targets or those of you with low vision, you may prefer the second set of instructions which is text that explains how to use the dropdown menus.
INSTRUCTIONS FOR REQUESTING AN IMAGE THROUGH SKYNET:
You will need two windows open, one for the instructions and one for Skynet. Arrange however is most helpful to you.
Click “Go to Skynet” on the very upper right corner of the SJS page you are on. The Skynet Junior Scholars account you are using will automatically sign you into Skynet and use the telescope time account allotted to you. This should be one of the windows you will be using.
Next, decide which type of instructions you would like and open those in the second window:
1. The first set of instructions is a link to a video transcript with screenshots for requesting an image using the Sky Viewer. This is best suited for visual or deaf and hard of hearing individuals.
OR
This link will take you to a 21:37 minute video explaining the process in detail. It is best suited for sighted, deaf and hard of hearing, and low vision.
2. This link takes you to instructions that do NOT use the Sky Viewer. Instead it uses drop down menus to select information about KNOWN targets. This may be the easiest to use when you are making your first several image requests.
After you make your first image request, please skip down to # 5 where Chris explains the use of the Observation Journal. Record your information there. Then continue with the instructions for checking the status of your first image.
Please make FOUR more image requests using any target in the drop down menus (instruction set #2 above). Record the information in your Observation Journal.
The information in Part K will help you decide if your image is “good” or “bad”. You may skip Parts J, L, M and N.
*****************************************

Now we are ready to learn how to request an image. Over the next several parts, Chris will explain the commands you have control of. The first 7 lines of code you see in the Quorum Box for image requests you do NOT have control over. These involve Skynet finding your account and how much time you have available to use on each telescope. This is done automatically for you using the SJS account you are currently signed in with.
You may listen to Chris in this 2:25 video to explain the first steps and the telescope command, or you may skip to below the video and read the instructions there. A PDF of a textfile of the commands of this Part are also available:

************************************************************************
Use the Quorum Box for Image Requests in the link below, which will open in a new tab. Depending on your vision level, it might be helpful to have these instructions and the Quorum Box open in two windows at the same time as a split screen. Or use ctrl tab# to switch between the two windows.
1. In the Quorum Box, the first seven lines have been automatically loaded. Again, these call the various libraries and token for your time account.
*NOTE: If you are copying and pasting the code into the Quorum Box with the screen reader mode turned off (unchecked), you will notice extra spaces between lines and after some numbers. The Quorum language does NOT depend on these extra spaces. You can delete them for a more elegant looking script if you would like.
2. You are now ready to type in your first command. This command informs Skynet, through Quorum commands, which telescope you want to use. Make sure you type the telescope name exactly as it appears, and use the parentheses (this tells Quorum which variable to use for the AddTelescope function) and quotes (simply means that the AddTelescope input is a text variable).
skynet:AddTelescope(“Prompt6”)
For now, we will use Prompt6 in Chile as our telescope.
3. You may copy and paste the rest of the commands listed below, or type them out one by one (or use the text file resource mentioned above). It has a target already specified by our astronomer, Tyler. You will get to pick your target in the next image request.
4. Once you have inserted the following code into the Quorum Box, click the BUILD button to check your code. If it is NOT successful, check how it copied: for example, sometimes quote marks do not copy correctly. If it is successful, click RUN for your first image request.
skynet:SetRightAscension(“12:39:59.4”)
skynet:SetDeclination(“-11:37:23”)
skynet:SetName(“M104”)
skynet:SetMaxSun(-12)
skynet:SetMinElevation(30.0)
skynet:AddFilter(“Clear”)
skynet:SetNumberOfExposures(2)
skynet:SetExposureLength(30.0)
skynet:SubmitObservationByCoordinates()
end
action ResponseReceived(text response)
output response
end
end
*************************************************************
5. You will be given instructions for checking the status of this image, but first, record the information about the image in the Observation Journal. Chris explains good reasons for using this journal in the 0:55 video. The link for the Observation Journal is below the video (or in the list on the right). The link will open the Journal in a new tab, which might be helpful to keep open for ALL of your image requests. You will need to look back at the commands you put into your Quorum Box for Image Requests to find the information to put in the Observation Journal.
*************************************************************

Opening Your First Image

Below is a link to the resource document on checking image status. OR, use the same, but BRIEF instructions given below the link.
1. Skynet BRIEF Instructions:
Go to the top right hand corner of any SJS page and click on “Go to Skynet”. Skynet will open in a new tab. Next, find the “My Observatory” button on the top banner. A drop down menu will appear as you scroll over My Observatory. The first item is “Optical Observing”. Click that and a table will appear on the left side of the page. The image you requested should be the first on the list. If it is ready, it will say “completed” in the last column. There are various issues that may cause the image not to be completed. The resource has a few hints for this. In the near future, Skynet will tell you what the error is.
2. Afterglow Access Instructions:
For the second way to check your image status, we will use the software program called Afterglow Access. Again, the resource document listed above provides the same instructions as the ones that follow.
The link below to Afterglow Access will open in a new tab (window). You may use ctrl tab# to switch between tabs, or arrange the windows side by side.
You may follow the instructions from the resource document linked previously, or continue reading here.
Once the link is open, login via Skynet – this is found to the right of the center of the screen.
**once you are logged in, if you would like to change the appearance of the program to suit you vision, go to the far right on the blue banner across the top of Afterglow Access and find your initials. If you click on this, a menu drops down with “Theme Editor” at the top. Here you may choose a color scheme, a font weight, and a font size.
Then move to the left of the screen directly under the words “Afterglow Access”. There are several icons which are named as you move across them. Find the one that that is titled “Open files”. Click on that. A popup screen will appear.
There are three file folders here. Choose the one titled Skynet Robotic Telescope Network. This will open to three more file folders.
Choose the last folder, “User Observations”. If any image you requested is complete, it will appear as a file folder here. Clicking on the file folder shows the raw image and the master calibrations folder. Click on the raw image folder. Click on the images present here, then go to the bottom right of the pop up window and click open. This will open the image in Afterglow Access.
We will be exploring Afterglow Access and all of its tools in Section 2.
Go to your Observation Journal in your open tab, or use the link below, to type a note about any image that was returned to you.
