Image Gallery

The Image Gallery collects every frame captured during your sessions into a browsable grid. Use it to review exposures, compare filters, check image quality, and manage storage.

Thumbnail Grid

Images are displayed in a 3-column grid with 4:3 aspect ratio thumbnails. Each thumbnail shows three pieces of information at a glance:

• Filter name — The filter used for the capture (e.g., L, R, G, B, Ha, OIII).
• Exposure — The integration time in seconds.
• Capture time — When the frame was taken.

Scroll the grid to browse your full image collection. The grid loads thumbnails progressively, so large sessions remain responsive.

Filtering and Sorting

A filter bar sits above the grid to help you narrow down the view.

• “All” chip — Selected by default. Shows every image in the gallery.
• Per-target filter chips — One chip appears for each target you have imaged. Tap a chip to show only images from that target.

Sorting options let you control the display order:

• Newest first — The default. Most recent captures appear at the top.
• Oldest first — Reverses the order so the earliest captures appear first.

Tip

Use the target filter chips to quickly isolate a single night’s data when reviewing a multi-target session.

Multi-Select Mode

Long-press any thumbnail to enter multi-select mode. In this mode:

• Tap additional thumbnails to add them to the selection. A checkmark appears on each selected image.
• A toolbar appears with batch actions, including delete selected.
• Tap a selected thumbnail again to deselect it.
• Exit multi-select mode by deselecting all images or tapping the cancel button.

Caution

Deleting images removes them permanently from the device. This cannot be undone. Double-check your selection before confirming a batch delete.

Single Image Viewer

Tap any thumbnail to open the full image viewer. The viewer shows the image at full resolution with standard pinch-to-zoom and pan gestures.

• Navigation — Swipe left or right to move between images in the current filtered view.
• Metadata overlay — The viewer displays detailed information about the frame:

Field	Description
Target name	The object or coordinates the frame was captured at
Filter	The filter in the optical path
Exposure	Integration time in seconds
Timestamp	Date and time of capture
File size	Size of the raw file on disk

Tap the image or the close button to return to the grid.

Footer Stats

The bottom of the gallery screen shows a summary bar with three statistics:

• Image count — The total number of frames matching the current filter.
• Total integration time — The combined exposure time of all displayed images, formatted in hours, minutes, and seconds.
• Storage used — The disk space consumed by the displayed images.

These stats update dynamically as you change filters or delete images.

Note

Storage figures reflect raw file sizes on device. If you have cloud sync enabled, the cloud copy does not count toward the local storage total shown here.

Workflow Tips

• Review before stacking. Scroll through thumbnails after a session to spot any frames with trailing, clouds, or artifacts before including them in a stack.
• Filter by target, then sort oldest-first to replay a session chronologically and watch conditions change over the night.
• Use multi-select to clean up test exposures, failed solves, or frames taken during setup. Removing junk frames keeps your gallery manageable and your storage free.
