Many thanks William, that was super helpful information from your friend. That validation has allowed me to have confidence in looking at other...
Thank you William for he pointers, I hadn't thought of looking down through the OTA to the STF/FW8/OAG (duh), I just did that and noticed the...
Yes, indicated in my post yesterday, with my eyepiece in it focuses perfectly, super crisp.
Right, when I move the focus knob manually from all-the-way out to all-the-way in, I go from donut to donut and the middle is hard to get exactly...
Just one last round to see if I can figure out my focus problem. This evening I tested focusing with both an eyepiece and then the STF on the...
Oh darn, when I saved my STF images first, then switched to the STi camera, and saved those over top of the STF (thus the file name)... so I lost...
Just saw your last post... looks like I uploaded the wrong FIT, I saved both the STi and the STF images... stand by, i'll get the right ones...
So, is my focus problem related, or is it something different entirely, or... is my particular setup doomed. At this point I just want to get...
Serial: 83F011187
Where can I find the serial number? Back to the original issue though, the focus problem, assuming the 5% variation isn't causing an issue with...
I recharged the desiccant, plugged it back in, and let it sit for two days before trying again... Attached is the flat I just took, shadow is...
Rotating the camera doesn't change the shadow. The front of the camera's chamber is clean, no smudges. How do I recharge the desiccant?
Attached are flats with the OAG removed, and then with the Filter Wheel also removed. The shadow appears to be there with just the STF. I've...
Regarding the f/11 beam, with the pickoff mirror back as far as it can go, I still get the shadow. The file "Flat-STF-Out-Full.fit" is the flat...

Here's a pic with the shutter open...
Right, sorry, forgot to mention, no different in the orientation of the camera assembly, attached is both the 45 and 90 degree orientation...
The panel is evenly eliminated, but just in case I did the experiment suggested, and the shadow stands still regardless of the orientation of the...
I use a light pad for flats, see attached...
I backed it off even further, now the edge of the pickoff is slightly outside of the edge of the CCD chip. The shadow is still there...
