The scale
Every thumbnail carries its own depth
Under every thumbnail, the scale gives the integration time accumulated on the object. Its length is the square root of the minutes, like the signal-to-noise ratio. The axis is the same everywhere, from zero to 22h 12. An object with little exposure is not a failure: it is young.
Temps d'intégration : the total exposure time, the sum of every exposure stacked on an object.

Of the 41 thumbnails on this page, 19 are cropped in on their subject, and the curve of 3 of them is lifted slightly, so that the object can be seen at card size; the photograph the entry opens full size gets neither treatment. The crop keeps the aspect ratio of the shot: the shape of the frame therefore still says which device it was, panoramic on the DWARF 3, square on the Unistellar and the Vaonis.
The designations
48 catalogue designations, and where they lead
One and the same photograph often carries several numbers, and it is under one or the other that people look for it. They are all here, sorted by catalogue. A number leads straight to the entry for the photograph, except when it has a page of its own: the page of numbers that run across two images, and the page of numbers whose neighbours say nothing of the kind.

Photograph by the author · location not logged
The ground, not the sky. It is mine, like the 56 shots above. Its location is not logged, so it is not written down. The coordinates on the entries, for their part, are read off the caption the device burns in itself.
With what
Every entry names its device
The instrument is read off the caption the device burns in itself, and every object entry links back to the entry for the device that made it. If a figure looks wrong to you, write in: the correction will be made and dated.
