ZWO OAG on ASI071MC

ozy

Two questions please:

Do the adapters that come with the ZWO OAG kit will match the backfocus on the ASIO71MC if paired with a ASI120S?

Would the OAG Pick-off prism occlude light onto the ASIO71MC sensor at F5? If so, what speed will occlusion disappear?

Sam@ZWO

Yes, you can use the ASI120S camera as guider camera

the prism won't block any light if you put it in proper place

Can the OAG hold the weight of another ASI cooled camera? I'm thinking of buying an ASI290MM for planetary use but would like it to do double duty as the guider to the ASI017MC.

Also, I can't find the OAG on any dealer sites except for ZWO directly. Is it too new?

the OAG can hold the cooled camera but the whole system is not as stable as a light weight guider

OK cool. As long the OAG itself is sturdy, I'm not worried about the full camera package weight. It will be going on the back of a Takahashi which can easily handle it.

I purchased the ZWO OAG for use with the ASI071MC. Since the ASI071MC only comes with an AR window, how can I insert a UV filter inline with the ZWO OAG?

I have it setup currently exactly as the manual states with the 21mm included spacer.

It seems that the ASI071MC needs a UV cut filter since it responds to UV area.

Sam@ZWO

usually UV won't be a problem
