For planetarium use only (lightly compressed zipped single frames). The dome masters can be downloaded and sliced into the configuration that suits the individual planetarium. Only supplied for long clips or shows.
Note: 1. Do not use Windows' built-in unzipper or Mac OS' standard Archive Utility (or unzip command) as they produce random frames (due to its default security settings). 2. As no network or browser is 100% stable, we strongly recommend using a download manager (like Free Download Manager1 or the command line tool aria2).

Note: 1. Do not use Windows' built-in unzipper or Mac OS' standard Archive Utility (or unzip command) as they produce random frames (on Windows due to its default security settings). 2. As no network or browser is 100% stable, we strongly recommend using a download manager (like Free Download Manager1 or the command line tool aria2).
Fulldome 8k Master N/A 8192 x 8192 30 .jpgs. Zipped with Winzip * dome_8kmaster For planetarium use only (lightly compressed zipped single frames). The dome masters can be downloaded and sliced into the configuration that suits the individual planetarium.
Note: 1. Do not use Windows' built-in unzipper or Mac OS' standard Archive Utility (or unzip command) as they produce random frames (due to its default security settings). 2. As no network or browser is 100% stable, we strongly recommend using a download manager (like Free Download Manager1 or the command line tool aria2).

1 In Free Download Manager we recommend setting: Options -> Settings -> Downloads -> New Download -> Advanced -> Connection: unclick "Maximum number of attempts" (to have infinite numbers of reconnection attempts). And please double-check that you have enough free disk space where you're saving. With this solution we believe that even up to 400 GB large files can be taken down on a personal DSL16000 line (at 1.8 MB/s) over a weekend in Europe.
