Sorry, I don't know. I don't do astrophotography and don't have the practical experience to comment on exposure lengths. Although, I would think...
-20 @ 35/40% is good for a STL.
I found it in the log book. May of 2006. 202oCM upgrade, no guider upgrade, also got the Back Plate and Handles.
A name and rough time frame should be sufficient for me to look it up. A serial number wouldn't hurt.
If you give me your name and a rough estimate of the time frame, I can look it up in my log book. A conversion from ST-7 to ST-2000 did not...

This'll have to come in, it has nothing to do with the Fan. It's a failure in the cooling circuitry. I have a STF board connected to my computer...
Turns out that the banding shows up in the Internal Guider as well, but only when the RGH is attached and cooling is on. Disconnect the RGH, no...
Yes, I think it needs to come in.
This camera definitely has the 237 Internal Guider.
You can check to make sure nothing is checked in the Debug Log of the DriverChecker.
I've seen them. It's very subtle. I wouldn't be surprised if it came out of Production this way. My guess would be the ccd.
You can get them from McMaster-Carr. The size is -050. The part number is 9396K132.

It doesn't appear that you're using the guider as "External". I notice in the lower right corner of the screen shot it says "Res: Tracking-Auto",...
Common causes of shutter errors are low input voltage and long USB cable runs without a powered hub. Either of these a possibility?
We're in contact.
Can't say I've seen that before. Looks like a mirror obstruction but... on the top and bottom? Not sure...
