Quick glossary — what these terms mean
Exposure
How long each frame is captured for. Longer = more light, but EQ mode is needed past ~15s to keep stars sharp.
Gain
Brightness amplification (0–100). Higher = brighter image but more noise. Most users start around 60.
Filter — VIS / Astro / Duo-Band
VIS for Moon and planets. Astro for galaxies and clusters under dark skies. Duo-Band cuts light pollution and moonlight, best for emission nebulae like M42.
EQ Mode
Equatorial tracking — rotates the field to follow the sky so long exposures stay sharp. Required for any exposure longer than ~15 seconds.
Frames
How many exposures were stacked. More frames = cleaner final image. 60–150 is a typical session.
Bortle Class
How dark the sky is, 1 (pristine) to 9 (inner city). Dark countryside ≈ 3, suburban garden ≈ 6, bright city ≈ 8. Skip if unsure.
