Hello,
Maybe I should open a new thread, but it might just fit in here as it is about digiscoping with the rx100 m3.(but some kind of newbie questions).
In fact I'm (re)starting digiscoping, did a few tries some years ago, but then due to a new camera not adapted, and various reasons, I didn't really pursue.
And I just bought a sony RX100 M3.
My scope is a swarovski ATS 80 with the 20 60 eye piece, and the DCB A adapter (the one replaced by the DCB II), so this one :
And I have --a lot-- of vignetting !
(much more than with the camera I tried some years ago I think)
Basically, the only position for which I can get rid of it, is the swaro eye piece at 20x (minimum), and the Sony zoom at maximum (70mm).
From there, if I increase the scope zoom level it appears, and if I decrease the camera zoom level it appears also.
Is it normal ?
And this by moving the camera the closest possible to the scope.
In fact the 70mm position for the Sony lense is not the max physical extension (I was surprised by that, but I am also kind of a noob in photography, so ...
).
So I could bring the camera closer to the scope when the rx lense is at 70mm (and leave the camera zoom there), but then the problem is, that when the camera switches off, the lens zoom goes to full extension before closing, so that it bumps into the scope ...
(and this with the "eye relief glass protection" piece of the scope pushed inside at the max, and taking it out provides only a 1mm gain or something)
Also, moving precisely the camera on the "horizontal" axis (towards the scope) is really not easy with the DCB A adaptator, there is really a lot of friction involved (with the lower lever released of course), is this also normal ?
So really some newbie questions.., but would appreciate any advise
Also, would it be possible that the 20x50 eyepiece brings very different results ?
It is described as particularly adapted to digiscoping on swaro site :
"this eyepiece is also excellent for digiscoping."

If it makes a major difference, maybe I could bite the bullet, 20x being quite a limitation in the current set up (even if it is already quite something in equivalent focal length with the sony at maximum)
Any info on that ?
