Issues with ASI174MM Mini and OAG use

seaber

Hi everyone,

I'm having a difficult time getting my new cam to work properly with my Celestron OAG. On fullsize cameras for example like my ASI224MC, you can unscrew the nose piece and thread extension tubes in order to achieve the correct distance from the OAG to the guide camera sensor. With this mini sized cam though I'm no longer able to do this. The end result is the cam sits to close to the prism and I end up getting a captures that look like this

What can I do to address this? Are there extender tubes for the mini cams?

Do you mean that the back focus is too long?

Maybe the adapters could be arranged again.

I thought I will have to use like ASI174 mini camera offers you very good performance for planetary imaging and guiding. Low read noise, high dynamic range, QE peak 77%, AR protective window and much more.

174 has bigger sensor than 224, so it is normal to show this field of view.
