Io personalmente non banalizzerei il problema parlando di strisciatine sulle lastre fotografiche.
La questione è molto più ampia e complessa, come ha già evidenziato Roberto Bacci *.
La questione è più ampia e complessa e fortunatamente c'è chi non punta i piedi per terra ma cerca di risolvere il problema:
NRAO Statement on Starlink and ‘Constellations’ of Communication Satellites
Recent news reports of planned constellations of communication satellites, including the SpaceX Starlink proposal, have pointed out the potential impacts these systems may have on radio astronomy. For decades, the U.S. National Radio Astronomy Observatory and the Green Bank Observatory, in cooperation with the National Science Foundation, have worked to ensure that innovations in communications can advance while still preserving our ability to explore the Universe from Earth and conduct essential fundamental research through radio astronomy.
Most recently, the NRAO and GBO have been working directly with SpaceX to jointly analyze and minimize any potential impacts from their proposed Starlink system. These discussions have been fruitful and are providing valuable guidelines that could be considered by other such systems as well. To date, SpaceX has demonstrated their respect for our concerns and their support for astronomy. This includes an agreed-upon protocol to monitor impacts and address issues to NRAO’s current and future cutting-edge research facilities.
We continue to monitor, analyze, and discuss the evolving parameters of the SpaceX system. Among the many proposals under consideration are defining exclusions zones and other mitigations around the National Science Foundation’s current radio astronomy facilities and the planned future antenna locations for the Next Generation Very Large Array. We also are working with our international partners, including the Square Kilometer Array, to present their concerns as well.
The NRAO looks forward to future discussions and is confident that the needs of both the research and communications communities can be met and preserved. [2]

L'unico punto di Bacci on-topic per l'astrofotografia/astronomia è questo:
9) Tutti questi satelliti disturberanno pesantemente le osservazioni astronomihce e radio, e anche noi astrofili che non usiamo il "sigma clip" ma fotometria o ricerca asteroidale.
Per la prima parte la questione non è ancora chiara. Non so quali fonti usi Bacci ma non mi risulta che i danni siano già stati quantificati e oggettivati (vedi sopra il testo in inglese - "may have").
Per la seconda già scrissi ieri che al massimo chi farà fotometria e ricerca asteroidale dovrà eseguire una più attenta programmazione per evitarli (pianificazione che son sicuro che chi pratica queste due area giá fa).
