Hi Sam,
I have received the ADC on 07/30/18 against my order on you. Thanks for your prompt service. My question is will levelling the bubble in the built-in spirit level make the ADC perfectly horizontal? Looking forward for your help on this please.

Hi,
If using this with a 2.25x barlow and 290MC does it matter if it goes before the barlow or between the barlow and camera ?

Sean Wang – :
It’s all OK, if your camera can on focus.

Purchased the ADC on 11/16/2017 and see that the new one has a built in bubble level which facilitates leveling with the horizon. Is there any way to upgrade the adjustment ring to the one with the bubble level?

Hi Sam,
My optical train is 8se scope / GSO Focuser / ES 2x Focal Extender / ZWO Filter Wheel (w/ Astronomik LRGB filters) / ZWO ASI120MM-S camera.
Where should I put the ADC in the chain? You can see a photo of my setup on Astrobin via the link below.

BTW, all of my ZWO hardware works great! I am really looking forward to trying out the ADC to see if it can help improve my planetary images (and visual use)!
Thanks,
Pat
