Telescope Log: Darksite

Telescope log and stargazing planner for amateur astronomers. Darksite starts with a short list of targets matched to your telescope, eyepieces, location and tonight's conditions. See the dark window, moon schedule, cloud outlook and the reason each target fits your setup.

PLAN AND LOG THE SESSION

• Built in and offline: 13,000+ deep-sky objects (Messier, NGC, IC and more), the planets and the Moon

• Queue tonight's targets and reorder them by transit time

• Use red field mode and the custom red keyboard at the eyepiece

• Record seeing and transparency with sketches, voice notes and photos

• Capture date, time, site, gear, magnification and field of view

TOOLS FOR YOUR GEAR

• Add telescopes, eyepieces, filters and Barlow lenses

• Calculate magnification, true field of view and exit pupil for each combination

• Search sessions by object, eyepiece, site or sky quality

TRACK OBSERVING LISTS
