Would it be off topic in this SE?
It may or may not be on topic here.
It's definitely on topic at the new Astronomy.SE, though. I suspect you'd be likely to find more targeted expertise on that site, so I strongly suggest you ask it there.
See Astronomy SE questions tagged astrophotography or photography.
