Changing background values on STi images. Causing guiding problems and star fades.

Should I send my FW8G-STT too? It is doing exactly the same thing.

 

It is the guider images. I posted some samples a while back. About every couple of minutes extra random signal is added to my guide images.

 

Yes, TSX. I haven't tried with CCDOPS. I did buy Maxim but haven't had the time to re-learn all of my workflows so I haven't tried it. I got frustrated and pull the 8300 off my remote scope. But I can try CCDOPS here at home pretty easily I think.

 

I'm willing to send my camera in. What kind of expense are we looking at? I don't want to put a lot of money into a $600 camera.

I'm also skeptical that this is hardware. Obviously I'm not the only one, my friend has one in the same observatory, it is doing the exact same thing on a different and more modern PC, another friend I have spoken with, his does the same thing. The same chip in the built in filter wheel does it also as Kevin has just mentioned. I've seen many other users with this chip in either the STi or filter wheel describe the exact same thing.

 

My friend that I share an observatory with uses PHD, same thing happens. We did try a trial version of Maxim, same result.

My other friend who lives in the same state Dan, I think he may have posted about it sees the same thing, he uses Maxim version 5 so he was unable to save any guide images.

 

OK thanks, looking forward to the results.

 

I was able to hook up the camera in the house and watch CCDOPs shoot guide exposures for a while. This is without a scope and not a perfect test by any means but I did see occasional exposures with large sharp deviations in the counts if I'm reading CCDOPs correctly. This is using a different computer than I use at the remote site. Sorry I haven't been able it test more thoroughly - I'm in the process of moving house and haven't been able to get the scope set up.

 

Yes, think we are in the same boat. You saw my post and screen shots. I saw one tonight with multi-star but it seemed to ignore the error in offset.

 

Been almost 10 months now since I first posted this problem. We finally have a clear night here, I'm trying to guide, about every third to fourth image is all noise. Any updates? This is really frustrating.

 

Hi Joshua,

There's a checkbox that defaults to "on" (checked) in the SBIG Universal Settings dialog called "Auto-Expose After Filter Change".
If it's on, please uncheck it, and let me know if it helps.

Thanks.

Hi Owen, yet it is checked so I will turn it off. Weather is not looking good for any clear skies to test for a while unless dark frames would tell you anything? I take darks easily.

 

Where does one find the SBIG universal settings dialog? Note, that I use TSX for camera control.

Thanks,

Kevin

 

The setting is in MaximDL, I have no idea if there is an equivalent setting in TSX.
