Issues with the Telephoto Lens on Dwarf Mini

Issues with the Telephoto Lens on Dwarf Mini

Good morning everyone,

Last night I went to set up after the Dwarf Lab software update for the Dwarf Mini. I had perfectly clear skies, but when I would autofocus (and then subsequently, try to manual focus) nothing happened on the telephoto lens. It kept saying that the autofocus failed, and to make sure nothing (clouds or other objects) were not obstructing it. There were no clouds in the sky, I could see *a lot* of stars by eye and through the wide lens. I attempted to up the gain, and shutter speed to see if that helped, and I got the following image:

I spent all night trying to get it to work, but nothing was working. This morning, I tried messing with it some more, and I tried focusing again and doing the same thing, and I still got the weird noise. The following image is the next morning on something in my living room to see if that would help *at all*:

I then dropped the gain and shutter back down to what I would normally do, and tried to shine a light in there, to see what would come across, and the following image is what I was able to see:

It almost looks as if the actual camera is crooked or slanted, and is not actually pointing directly out of the lens. I tried googling and looking at other people who may have had a similar issue. I've tapped on the arm, to see if I could get it back in place, but nothing I tried work, and it's still just acting like it can not see anything out of the telephoto lens. Any help you guys can provide would be greatly appreciated.

And to not waste your guys' time, here is an image I capture with it over multiple nights of M51 (the Whirlpool Galaxy). Exposure: 227x60s (3h47m) at 60 gain in EQ mode (Bortle 7, northern hemisphere). I edited it myself with PixInsight and Photoshop.

Thanks again if you can provide any help, or if you just like the image I got of M51!

EDIT - Here are the images of the interior of the camera

EDIT 2 - I went out to see if I even could get an image of the sun. This is what I got. It is clearly centered in the wide lens, but nothing on the telephoto lens along with an error message saying "The Sun not detected". (Yes, the solar filter is on)
