What AstroCam is for and who it suits

AstroCam is a camera app for shooting the night sky with an Android phone. Its main job is to take a series of long exposures and combine them, so that faint stars, galaxies and the Milky Way come out cleaner than a single dark shot would allow.

The listing presents it for people who want to photograph stars and then work on the results. Beginners can use the automatic stacking and the one-tap time-lapse. People who want more control can set exposure and ISO by hand, and the Moon, planet and telescope modes are aimed at astrophotographers who already have some equipment and experience.

Stacking frames for cleaner night sky photos

Frame stacking is the core of the app. Rather than taking one noisy exposure, AstroCam captures many long-exposure frames and combines them mathematically. You choose how many frames to stack, anywhere from 10 to 400, depending on how much detail you want in the final image.

The stacked result passes through processing for sharpening, noise reduction, color correction and brightness. After that, post-brightness and white balance sliders let you adjust the look. The listing also includes an Auto-Discovery step, which tests the camera hardware and looks for the longest exposure the sensor supports, so you do not have to find that limit by trial and error.

Star trail and night time-lapse video

Star Trail mode blends frames over time so that the stars draw arcs across the image. Max Blend gives bolder, more vivid trails. Weighted blend gives a softer result. The Decay Factor sets how long each trail stays visible, running from 0.99 for long, smooth trails to 0.10 for short, sharp ones.

Star trails can be saved as a photo or as a video recorded at 24, 30 or 60 fps. Night Lapse works differently. It sequences hundreds of long-exposure frames into a time-lapse, so rising stars, drifting clouds and the turning Milky Way appear in one clip. The listing says it starts with a single tap.

Manual exposure and reaching longer exposures

Full manual control gives you direct settings for exposure time and ISO. This is the part of the app for people who want to decide the exposure themselves rather than rely on the phone's automatic mode.

The listing says AstroCam can sometimes reach exposures longer than standard camera apps allow. Whether that happens depends on the phone's sensor, which is why the Auto-Discovery step exists to measure it.

Lucky Imaging and Advanced Stacking for Moon and planets

Advanced Stacking is aimed at Moon, planetary, and deep-sky captures, including images taken through a telescope. It offers two engines. Lucky Imaging with Weighted Average scores every frame and blends the sharpest ones. Lucky Imaging with Drizzle uses sub-pixel accumulation to pull out more fine detail.

You decide how much of the footage to keep, from the sharpest 25% up to ALL frames. You can pick a custom base frame, align the stack around it, and crop before processing. The finished image can be exported as PNG, JPEG or TIFF. The listing describes this as the planetary workflow, and it is the part of the app most tied to telescope work.

Saving raw frames and choosing capture resolution

Raw Save mode writes each individual frame at full resolution to your gallery or to a folder you choose. The listing names Lightroom and Photoshop as places to edit those files, though any photo editor can open them.

Capture resolution can be set to 360p, 480p, 720p, 1080p or 4K. The listing says the choice depends on how much storage you have and how much detail you need.
