What this sheet is for
Turn a night at the eyepiece into a record you can compare with the next one, with the sketch on the same sheet as the conditions it was made under.
Who it is for
Visual observers, sketchers and anyone working through an observing list with a telescope or binoculars.
How to use it
- Fill in the site and instrument at the start of the session.
- Name the seeing and transparency scale you use in the notes on the first line.
- Log the object as you observe it, with the eyepiece and magnification you were using.
- Sketch in the grid below while the object is still in the field of view.
- Mark north and the direction of drift on each sketch — a sketch without them is hard to read later.
What is on the sheet
One page, top to bottom:
Printed under the title: One line per object — when you looked, what you looked through, how the sky was by your own judgement, and what was actually visible.
Your scale, named once. Seeing and transparency are blank columns here, not a printed scale. Use whichever scale you already work to and name it in the notes, so that your own nights can be compared with each other.
Write-on lines: Observer · Site · Session / date
Table, 7 rows: Date · Time · Object · Instrument · Eyepiece / mag · Seeing · Transparency · Notes
Sketch — one object per box, with north and the eyepiece field marked

Questions
Why are seeing and transparency blank columns rather than a printed scale?
Because several scales are in use and observers are attached to the one they know. A scale printed here would quietly clash with the one in your other records. Name yours once and the columns then mean something.
What is the grid at the bottom for?
Sketching. Use one area per object and mark the eyepiece field, north and the drift direction. The squares are there to keep proportions honest, not to be filled in.
