I use a Sony A7R II and I shoot a lot in electronic mode but not for astro. Electronic mode does not work in bulb mode . Not a problem because is use mostly ( or I did shoot mostly when the skies were clear , a long time ago ) 5 to 10 minutes exposure . This wil not harm the shutter .

My strategy is lots of 30 sec exposures and silent shutter. Have some light pollution so using longer sub exposures do not add anything - besides some added blur by turbulence.

And no guiding needed! Grab and go. Why complicate things with looong exposures just because the mindset is stuck in the needs of the CCD era. We are into CMOS now.

Modern image sensors have very low read noise so that is a non issue in my case. Read noise is way less than the noise from the light pollution anyway. Have tried this out.

If the site is dark then go for longer sub exposures.

Below: M31 and lots of 30 sec sub exposures.
