ASI1600MM-cool Tilt?

wadeh

Hello,

I have an ASI1600MM-cool that I bought earlier this year. The weather has been pretty poor here, but I have finally had a chance to try it out in a couple of configurations.

I believe that the sensor in the camera may be tilted. I cannot get properly formed stars across the entire field. My automation focuses on a star in the center of the field, and that area is fine. The right side of the frame tends to be the place where the problem is greatest. This is true if, regardless of the orientation of the camera (ie. if I rotate the camera, the problem stays in the same place in the frame) and regardless of the point in the sky where it's aimed (it is not a flex problem). The same problem shows up with two different scopes that I've tried: a 384mm focal length refractor with field flattener, and an SCT at 1655mm. I have attached an image from the SCT with samples from the center of the frame and each corner to show what I am seeing. If this looks like some problem other than tilt, I would be interested in opinions.

I have not yet had a chance to bench test the camera off of the scope to test for orthogonality of the sensor. My question is, assuming that I can confirm a tilt, is there a way to adjust it in the camera, or will the camera need to be sent in for repair or exchange?

Thanks.

Hi Wade

we provide one T2 tilter to adjust the focal plane

here is it

we measure the distance from sensor corner to the interface before out of factory

we can recheck it for your need

Thanks for the response.

Does this mean that the camera cannot be user adjusted? Also, you say that you can check the tilt. How long is the turnaround time for that?

Finally, I have looked at the tilt adjuster that you reference. How does that work with the filter wheel? It seems like the thumbscrews would prevent attaching the filter wheel to the camera. Also, it takes up valuable back focus, which I don't want to give up. It seems like the camera's sensor should be orthogonal without requiring an adapter.

we check and adjust should be very quick once we got the camera

It's a little hard for user to adjust it as you need to open the cover and measure the 4 corner
