A filter name is not an equipment ID

A FITS FILTER value such as Ha, L or OIII describes your capture configuration. It does not uniquely identify the manufacturer's product, size or revision. AstroBin's CSV filter field uses a numeric equipment ID, not that header label.

Make an explicit equipment decision

1. Find the filter you actually used in AstroBin's equipment database.
2. Check the manufacturer's name and product details. A matching short label is insufficient.
3. Copy the numeric ID from that filter's equipment-page URL, as described in AstroBin's official import documentation.
4. Enter that ID beside the corresponding source filter in this sheet. Check the imported acquisition row after the CSV handoff.

The sheet accepts positive digit strings and does not fetch or verify equipment records. A syntactically numeric value may still name the wrong filter or no existing filter. You must make that check yourself. No prefilled real IDs are supplied.

When you cannot identify a filter

Filter is optional in AstroBin's documented long-exposure CSV. Select Leave filter field blank if you intentionally want to export without an equipment association. This leaves that cell empty while preserving the frame count and duration. It does not exclude those frames.

If FILTER is missing, the sheet creates a separate missing-filter decision. You may enter a known source label in the frame row, then map it, or explicitly omit the CSV field. Never substitute a familiar product ID merely to unblock export.

Mixed rigs need separate reviews

If two different physical filters both appear as Ha in one selection, the shared header label is ambiguous. Correct the per-frame labels to distinguish them, then map each separately, or split the source files into separate reviews. The tool cannot infer equipment identity from a short label.

The JSON audit records source labels and your mapping decisions. See how those decisions appear in the CSV.
