I am interested in modifying my Sony A7r2 for astro if I can.
I have been told it can be replaced with a Baader but because Sony A7xxx models from second generation up use an IR unit in the shutter it can get into the modded sensor if the exposures are too long.

I was thinking perhaps a different filter may work better like Astrodon or Astronomik or I believe there is a Canon version.
I just found out about a workaround for the star eater issue of the A7r2 cameras so that makes it even more worthwhile to use. The 42.4mp sensor is amazing so I would like to continue to use it.

Anyone have any suggestions?

Greg.
