I'm sad to report that the dew issue appeared again tonight. Another wasted imaging night because of this very same issue.

I cannot understand how a brand new product can behave in such a way that the user cannot use it as intended. I'm clearly unsatisfied with a product that doesn't fulfill the specifications (anti-dew).

I'll ask the warranty from the dealer (OPT).

Regards,

Alfredo

Hi.
I too. I've writen "Strange grid on my new ASI071MC PRO's sensor".

I'm amazed.
IMHO, from a big growing brand as ZWO, for these problems in top gamma cameras the only possible serious approch should be to call back and rapair the brand new defective camera in warranty (or best, to replace with a well working one).
But the only classic support from ZWO is to suggest is to try a "do-it-yourself" solutions (hoping that it will work).

I hope this the approch will change. This isn't a good advertising, I think.

Stefano.

I agree.

This is no single case issue, but more a recurrent issue happening to a lot of users.

It should be fixed.

We need an answer from a ZWO representative

I am having same issues with my brand new ASI 071 MC Pro.

I tried several methods including slow cooling to -15c in 20 to 30 minutes, changing dessicants with brand new spare ones, cooling and heating then cooling again... Nothing works. Serious dew pattern occurs on my sensor below 0c.

I am very unpleased with this camera because of this dew issue and gonna ask for replacement or refund if ZWO can't find a solution :(

For now, this is working for me:

1. I re dried the desiccant tablets with the microwave oven
2. Since then, I stored the camera on a hermetic jar with some small bags containing silica gel (see attached image).

The jar seems bigger than it is on the image. Take as reference the camera size.

This shouldn’t be necessary at all. But since it creates a dry environment for the camera, I haven’t had fogging issues since then. I only take the camera out of the jar when I’m going to use it. Let’s hope this keeps ...

I too am having dew issues with my ASI071MC Pro. I seem to have to dry the dessicant tabs every 4 months since getting it. I have done all the suggestions in the forums with no resolution. What is the resolution?
