A practical guide for amateur astronomers to fit observing guides into preparation time, organize useful videos and plan a session without rushing.

Choose the observing guides that match your next session, set aside time to review them, and write down the details you will need at the telescope. Keep useful guides in one place so you can return to them during preparation. If your guides are YouTube videos, YTSort can reorder a playlist you own by video length, putting shorter guides first or longer ones first. [^1]

| Option | How it helps organize guides | What to consider |
|---|---|---|
| Paper list or notebook | Record guide titles, subjects and preparation notes. | The order and updates are handled by hand. |
| Spreadsheet | Sort a list of guides by a length column you fill in. | Check the spreadsheet app's own features and cost. |
| Calendar or written schedule | Set aside preparation periods for reviewing guides. | Check the scheduling options available in the method you use. |
| YTSort | Reorders a YouTube playlist you own by video length, shortest or longest first. [^1] | Free; the Chrome Web Store extension, browser script and bookmark include the same features. [^1] [^1] |

## What you need before you start

Fitting observing guides into preparation time starts with knowing what you plan to observe and what information you still need. A little organization before opening a guide can prevent preparation from taking over the time intended for observing.

- **A session goal.** Decide what you want to observe during your next session. A clear goal helps you choose guides that relate to the objects or observing activities you have planned.
- **A list of useful guides.** Gather the reading material, videos or other guides that cover the subjects you need. Keep the list focused on the upcoming session rather than collecting material without a reason.
- **A record of preparation time.** Decide when you can review the material. A free period before the observing session can work better than trying to fit everything in immediately before going outside.
- **A place for notes.** Use a notebook, paper list or spreadsheet to record useful information. Keep observing instructions and reminders somewhere easy to find.
- **A way to organize video guides.** If you use YouTube, a playlist can keep related videos together. A browser tool can help arrange a playlist when video length matters.

It also helps to separate information needed before the session from material that can wait. Basic preparation should leave enough time to review the plan, gather equipment and get ready to observe.

## Step by step

These steps work whether your observing guides are printed, saved in a document or collected as online videos.

1. **Choose the next observing session.** Start with the objects or activities you intend to cover. A session focused on a particular subject gives you a reason to select relevant guides instead of reviewing unrelated material.
2. **Gather the guides you already have.** Look through your notes, saved reading material and video lists. Collect the material that relates to your session in one place.
3. **Separate essential information from extra reading.** Identify the instructions and explanations you need before observing. Put background material and additional topics on a separate list so they do not take over the preparation period.
4. **Check the length of each guide.** Look at how much time each video or reading item is likely to require. Short guides can be reviewed during a brief free period, while longer material may need a separate preparation session.
5. **Put the guides in a useful order.** Start with material that explains the subject or gives you the information needed for the session. Follow with guides that provide additional detail. If time is limited, put the shorter relevant material near the top.
6. **Choose a preparation period.** Decide when to review the guides. Leave enough time to understand the information rather than simply finishing a list of videos. Avoid making the preparation period compete with the observing session itself.
7. **Write down the important points.** Record the information you want to remember. Keep the notes brief enough to review easily when preparing to observe.
8. **Check what remains unclear.** After reviewing the guides, identify questions that still need attention. Find material that addresses those questions instead of repeatedly reviewing information you already understand.
9. **Prepare the observing plan.** Bring together the relevant notes and information for the session. Keep the plan easy to consult so you do not need to search through every guide again.
10. **Review the process after observing.** Note which guides were useful and which topics need more preparation next time. Move unnecessary material out of the immediate preparation list.

The aim is not to watch or read everything available. It is to make sure the information needed for the next observing session is ready when it is needed. A short, focused preparation routine can also make it easier to return to unfinished material later.

## Tools that can do it

You do not need dedicated software to organize observing guides. The right approach depends on whether your material is written, spread across several sources or collected as YouTube videos.

**Paper list or notebook.** Write down each guide, its subject and the preparation notes that matter. Arrange the list in the order you want to review it. This gives you a simple record to consult before a session. The cost depends on what you already own.

**A spreadsheet.** Use columns for the guide title, subject, length and preparation status. Sorting by length can help bring shorter material to the top when preparation time is limited. You can also keep notes about which subjects still need attention. Facts about specific spreadsheet apps are not provided here, so check their own pages for limits and cost.

**A calendar or written schedule.** Set aside preparation periods and assign guides to them. This can help keep longer reading or video material separate from the time reserved for observing. Check the scheduling options available in the calendar you already use.

**YTSort.** YTSort is made by the team that publishes this site. It reorders a YouTube playlist you own by video length, shortest or longest first. [^1] This can help put shorter observing guides near the beginning of a playlist when preparation time is limited. [^1]

YTSort shows the before and after order so you can check it before applying. [^1] It sorts the full playlist rather than only the videos loaded on screen. [^1] It can also sort videos within a chosen length range and move the remaining videos to the end. [^1]

You can use YTSort to review playlist duration information, including the total, average, shortest and longest video durations. [^1] It can export each video's position, title, duration and URL to a CSV file. [^1]

You can get YTSort through a bookmark, a browser script, or a Chrome Web Store extension. [^1] The extension needs Chrome or Edge, and the script version works in any browser, including Firefox, with Tampermonkey, Violentmonkey or Greasemonkey installed. [^1] YTSort is free, and all install options include the same features. [^1]

YTSort reorders a YouTube playlist you own by video length, shortest or longest first. [^1] For printed guides, reading lists or material outside YouTube playlists, a notebook or spreadsheet can keep the preparation plan organized.

## Common mistakes to avoid

**Collecting too many guides.** Saving every interesting observing video can make preparation feel like another project. Start with material related to the next session and keep unrelated guides for another time.

**Choosing guides without checking their length.** A useful guide may take longer to review than the available preparation period allows. Check the expected time before deciding where it belongs in the schedule.

**Confusing preparation with observing.** Spending the entire available period reading and watching videos leaves less time for the activity itself. Set a stopping point for preparation and keep the session plan focused.

**Putting everything in one unstructured list.** Guides about different subjects can become difficult to find when they are mixed together. Group related material and give each item a clear title.

**Sorting by length without considering the subject.** The shortest guide is not automatically the most relevant one. Check that the material addresses the subject you intend to observe before moving it to the top.

**Forgetting to keep useful notes.** Reviewing the same material repeatedly can take up preparation time. Write down the information you want to retain and keep those notes with the observing plan.

**Never reviewing the preparation routine.** A guide that was useful for one session may not be needed for the next. After observing, update the list and keep the material that remains relevant.

## Things to check before you choose

Before settling on a way to organize observing guides, check how you normally use them.

- Does the method handle written guides as well as videos?
- Can related guides be grouped by observing subject?
- Can you see how long a video will take to review?
- Can you keep notes alongside the material?
- If you use YouTube, does the playlist belong to your account?
- Do you need to arrange every video or only those within a particular length range?
- Does the method let you review the proposed order before changing a playlist?
- Can you access the material in the browser or format you normally use?

For a mixed collection of reading material and videos, a written list or spreadsheet can provide a common place for preparation notes. For a YouTube playlist where video length is the main concern, YTSort provides a way to reorder the videos by duration. [^1]

Choose an approach that makes the next observing session easier to prepare for. The goal is to spend preparation time on information that matters, rather than on repeatedly organizing the material.

## Frequently asked questions

### How can amateur astronomers fit observing guides into preparation time?

Start by choosing the subject of the next observing session. Gather only the guides related to that subject, check their length and put the essential information first. Set aside a preparation period and record useful points in a notebook or spreadsheet. Keep additional reading for another time so preparation does not take over the session.

### Should observing guides be organized by length or subject?

Subject should help determine which guides are relevant to the next session. Length can then help decide which ones to review first when time is limited. A short guide is not necessarily the most useful guide for a particular subject. Keep the important material near the beginning and use length as an additional way to arrange it.

### Can YTSort organize YouTube observing guides?

Yes. YTSort reorders a YouTube playlist you own by video length, with the shortest or longest videos first. [^1] It also shows the proposed before and after order so you can check the arrangement before applying it. [^1]

### Which browsers work with YTSort?

The YTSort extension needs Chrome or Edge. The browser script works in any browser, including Firefox, once you add a script manager such as Tampermonkey, Violentmonkey or Greasemonkey. [^1] YTSort can also be run from a bookmark. [^1] Check the installation instructions for the option you intend to use.

### Is YTSort free for amateur astronomers?

Yes. YTSort is free, and all installation options include the same features. [^1] It is open-source software under the GPL-2.0-only licence. [^1] The extension needs Chrome or Edge, while the browser script supports Firefox and other browsers when used with a compatible script manager. [^1]

### How much time should amateur astronomers spend reviewing observing guides?

The time depends on the material and the needs of the upcoming session. Start by identifying the information that needs to be ready before observing. Separate essential instructions from additional reading, then schedule the remaining material for another preparation period. Check whether the time spent reviewing guides leaves enough room to prepare the observing plan.
