Setting up a remote observatory for the first time can seem so easy that first-time remote astronomers neglect to to the fundamentals OR visions of disasters and loss of physical proximity can make it all seem overwhelming.
A commissioning plan ensures it's not either.
In this post, we’ll detail the importance of a commissioning plan for your remote observatory, walk you through how to create one, and share tips to ensure your setup is primed for celestial exploration.
What is a Commissioning Plan?
A commissioning plan is a systematic outline that specifies what needs to be done to verify that all aspects of your remote observatory are operational.
Think of it as a detailed checklist for your setup. It highlights tasks needed to confirm, validate, and finalize the installation of your equipment and systems. This structured approach not only helps in quickly addressing any issues but also ensures a smooth setup process, saving you from complications later on.
Why is a Commissioning Plan Important?
Ensures Quality Control
A thoughtful commissioning plan guarantees that everything, from your telescope to the power supply, functions as intended. In fact, studies show that roughly 30% of amateur astronomers experience equipment failures during observing sessions. Avoiding these issues is key to enhancing your overall experience and protecting your investment.
Optimizes Performance
An organized plan helps you discover the best settings for your telescope, including optimal focus and perfect alignment. For instance, aligning your telescope to within 1 arcminute can significantly improve your image quality and tracking accuracy, allowing for sharper images of distant galaxies and nebulae.
Time Management
If you're visitng SROF to setup your own system, you'll find that time can quickly get away from you - especially if you aren't clear on what's important for th ecimmisioning versus ongoing maintenance. By outlining each critical element to test in your commissioning plan, you’ll save valuable time during the setup phase and ensure you're not distracted by the temptation to fiddle now with something that can be done remotely later.
Why START with a commissioning plan?
It might seem odd to start with a commisioning plan, but there's some logic to it. It's actually an idea we borrowed from teh software development world, a concept called "Test Driven Development".
By starting with your test plan in mind, it focuses you on what "complete" looks like. In other words, what are your criteria for success?
This thought then prompts a list of requirements that rapidly translates into equipment, software, processes and automation and most importnatly TESTS you can run to ensure that you're getting what you expected.
Don't expect to get the entire plan right from the first draft, it's often iterative - with the plan infomring design decisions and design limitations then informing the plan.
Key Elements of a Commissioning Plan
Creating a commissioning plan can seem daunting, but it can be straightforward. Here are vital components to include:
1. Inventory of Equipment
Make a comprehensive list of all equipment you’ll be using. This includes your telescope, cameras, mounts, computers, software, and power supplies. Keeping this inventory ensures nothing falls through the cracks during the commissioning process. For example, forgetting a crucial cable can delay your setup by hours.
2. Setup Instructions
Thoroughly document the setup for each piece of equipment. Including diagrams can be highly beneficial for visualizing configurations. This practice not only aids your future setups but can also be invaluable when collaborating with others.
3. Calibration Procedures
Clearly outline how to calibrate your telescope and sensors. Assign specific tasks for focusing and aligning instruments. Calibration is essential for achieving accurate results, and having a systematic approach can make a typically tedious process much quicker.
4. Testing Protocols
Design a testing protocol to verify your equipment's functionality. Key tests should include:
Pointing: the majority of our guests are from the Northern Hemisphere and if they've been doing things right, have usually done a full setup and shake down test prior to arriving on site. There's one catch though. They often forget their setup is configured for the Northern Hemisphere and/or another time zone - as a result the first pointing session is critical to ensure the basics are right.
Network Connectivity: This is a huge one, confirm you can connect from outside of the observatory.
Power failure recovery: The biggest challenge of all - can you remotely power cycle everything and have the system come back in a known good, accessible state? We've had situations where remote power switches defaulted to the off state, leaving the entire system inaccessible after a power cycle.
Rain/weather testing: we supply small squirty bottles of DI water for just such tests! if the weather turns bad you want to know that hte observaotyr does what you expect it to do.
We often recommend going back to your off-site accomodation shortly after getting to this phase and testing that you can indeed get to the system without any glitches. It's also a great time to do a full imaging run and test BEFORE you leave, think of it as a simulation with a safety net.
5. Troubleshooting Guide
It's wise to anticipate the issues you might encounter during setup. Create a troubleshooting guide that details common problems, their symptoms, and solutions. This resource can save you significant frustration, especially during your first few nights of operations.
We love to get a copy of these, they help a lot, especllay with specialised mounts or equipment we've not encountered before.
Final Checks Before First Light
Before starting your first observing session, perform these essential final checks:
Capture darks and bias data: many modern CMOS cameras lack shutters, getting this data is an often forgetten step. Don't forget your guide camera!
Backup Software Settings: Even if it's a text file somewhere, having critical settings documented helps enourmously if something gets wiped by accident.
Power loss recovery!: We'll say it again, make sure everything comes up ready to work after a simulated power loss.
By performing these steps, you will ensure that your observatory is ready for work.
Common Mistakes to Avoid
While a solid commissioning plan is your best defense against typical pitfalls, mistakes can still happen. Here are common missteps to keep in mind:
Skipping Steps: Resist the urge to rush through your commissioning process. Every step is vital.
Neglecting Routine Checks: Regular testing and calibration should become part of your ongoing maintenance to ensure peak performance.
Managing Software Updates: This is a tricky one. Some software updates are GREAT - they give you new features or remove a bug. Others are just the opposite, they take what was a perfectly functioning system and suddenly everything stops working! Whilst we don't recommend NOT updating (for security reasons), we're also wary of updates for update's sake - especially on elements that are integrated with others such as with ASCOM drivers. When in doubt, creating a test platform back at home and test there before doing anything remotely.
Awareness of these pitfalls can save you time and enhance your overall observing experience.
In Summary
Creating a commissioning plan sounds a bit over the top, but it really does help you get the most out of your time on-site and greatly reduces headaches on an ongoing basis.
