Trouble getting ZWO 2600mc pro camera focus

Barnowl12

To whom it may concern:
First a little background. I am fairly new to using telescopes, but very familiar to SLR cameras. Over the last three years I have been putting together a telescope set up so that I can do some astrophotography. I have the ZWO 2600mc pro camera attached to my Celestron Edge HD 8 scope with a .7 focal reducer. I have checked the back focus using t adapter and also ZWO filter drawer. Please see picture below.

My issue is that I can not get the camera to focus. I have tried using Nina and Sharpcap. I have a zwo mini guide camera that I do not have a problem focusing.

When I try to slew and center to object and focus the screen looks like the picture below. I try to adjust the focus but it does not change. Any idea of what I am doing wrong or if someone is familiar with this behavior and knows how to solve it... Please let me know.

Still learning as I go. I am hoping to get past this issue. Appreciate any help.
Thanks,
Barbara

Hi,Your connection setup appears to be correct。what target are you trying to focus on? Try performing a focus test on a distant object during daytime—daytime tests work much better，Thanks

Important to remember:
You're focusing the telescope - not the camera.

What you should do, if possible, is setup indoors and, during the daytime, point it outside a window aiming for a spot 1km or more away and - with software that let's you pick "Video Mode" - try to get your telescope into Focus.

You can see how I've done this with the ASIAIR on my C8 SCT with f/6.3 Focal Reducer and ASI294MC Pro camera here:

It may also be worth your while asking this over on the Cloudy Night's Forums where people have a lot of experience with different software and telescopes.
