Hello all,

I am trying to place my OAG to get the most light and not interfere with the camera, below is the best I seem to be able to get. The field is being lit by a artist LED sketch board covering the OTA, what I use to generate flats, the scope is not in focus, this is the view I get.

Unobstructed And this is what the OAG looks like under the same light source.

Will it even work? Any help would be greatly appreciated.

An update on this:

I solved the light converge issue, it had to do with the light source I was using and location of the OAG in the image circle. I ended up having to use a paper spacer between the camera and the filter wheel to get it to position correctly. At least now the 290's sensor has some illumination across the entire sensor, every little bit helps.


What was more important was an article I found that tells how to get a rough focus on the OAG without having to struggle with it during the day then again at night. The key takeaway from the article is that the distance from the prism to the guide camera sensor must be the same as the distance from the prism to the imaging camera sensor. I was thinking that it needed to be the same as the distance to the FF.

Now waiting for clear skies, perhaps the sixth time out with the OAG will be a good one.
