G11 and 6” f/10 for imaging?

David Pitre All Messages By This Member #72537 I own a G11 and am considering putting together a 6” f/10 doublet for imaging the sun. Very high frame rate (>100 FPS) lucky imaging. I would put this on a very stout pier. Has anyone done anything similar??

Not great, but adequate. that was my thought. i'm probably a little more positive because it IS such short exposures it should be fine toggle quoted message Show quoted text On Thu, Jul 1, 2021 at 9:23 PM Joe Bergeron <joe@...> wrote: That should be adequate for such short exposures.

Chip Louie All Messages By This Member #72553 Jim, At 100 frames per second this should not be an issue. I've used a Skywatcher 150mm visually on a Losmandy G11 with classic drivetrain and it had no issues with vibration. Granted this is a 150mm f/8 scope so it is shorter but at over 300x any movement is easy to see with the mark I eyeball.? -- Chip Louie Chief Daydreamer Imagination Hardware? ? ?Astropheric Weather Forecast - South Pasadena, CA?
