Frank, I had a look at your images and they do look a little noisier than my ST2K. Mine normally end up with just a few dark/bright pixels although I use a 10 ...
... At first I was going to suggest cosmic rays, but I don't think that is the case. I took a look at your dark frames, and you're right - there are lots of ...
Hi Frank, Random 'hot pixels' are usually data errors of some kind. For example, they could be due to interruptions of the camera download as other computer...
Hi I have a Meade lx200 14" GPS, SBIG St2000xm, cfw08 and ao-7 that seems to be working well. Is it possible to fit on a focal reducer to this set-up that will...
David, Ted Agos builds an adapter for a FR that is frequently used with the AO-7. I have used it with some success with my LX200GPS 12", I am not certain if...
David, I second George's recommendation of Ted Agos's 6.3 reducer modification for the AO-7. I have used on with my LX-200GPS 12, LX-200 Classic 10, and my...
Hi group: Yesterday me and a friend Mario Santiago spent the night imaging M33 - The Pinwheel Galaxy. Our Objective was to get the h-alpha zones of this ...
I usually run CCDSoft and TheSky 6. I also control the laptop from the house using MS Remote Desktop via a network cable. I am running a series of tests now. I...
Iget these elongated stars with my FSQ-106 at times. It' may be a bit f astigmatism orcamea sag. Still ring to sort itout. If focus is dead on , it disappears....
Thanks Don I placed a picture in the files section under flyrcairplanes. Jeff ... to see the problem you are worried about. If you could upload a full sized...
Hi Frank: I've had that sort of salt & pepper artifact problem on occasion with my ST10-XME; don't know what causes it or cures it, seems to have its own ...
Jeff Very nice image. The stars on the left side of the image near the conners show evidence of coma. The right side seems OK, so that would lead me to think...
Jeff, Although I am by no means an expert, but It would appear to me to possibly be camera tilt. The elongation affects the stars more toward the left side of...
I think you are close, but I do see a defect on the right side: the stars at the top and bottom right corners are elongated vertically. The effect is small,...
The hot and cold pixel removal tools in MaxIM didn't do much at all. Instead I used the median kernel filter in MaxIM on each of my subframe right after...
I can't speak to the cause of your problem, although I think Terry's idea about CPU cycles possible being an issue is worth examination. When was the last time...

See my comments below. Ron ... --> That's very slow by today's standards. Could be an issue. ... There have been major changes during that year. An update is...
I'm sad to say that my test results are bad news. I took 3x15 minute dark frames at -15 degrees for each of the following: Original configuration as a base...
... Then you might want to update the camera drivers, as Ron and others suggested. I remember one fix a few months ago that sounded fairly major. Don't know if...
Rocketman: I agree with Steve. I think you have some kind of BW/transmission/network problem, or maybe even an EMI problem from some nearby source of transient...
Thanks for the input but I've been using this camera for over 2 years now. The observatory is less than 1 year old. This camera has always had this problem...
Ward, I finally programmed my TCF-S. To get the minimum 5 degree Celsius change for calibration took about 5 hours, which left me only 3 hours for my first...
Thanks to you both. I will recheck my setup and look into CCDInspector. Jeff . --- In ccd-newastro@yahoogroups.com, Wodaski - Yahoo <yahoo@...> ... the ... ...
Leonard: The "grounding" issue leaves me totally confused. If some of the equiptment operates off house current, some of it operates off 12 v battery, etc, ...
In order to help you on this problem, I conducted a number of test today: I took a series of 20 dark frame on a ST8E parallel port on a compaq presario. I got...
Hi Ron, I remember reading about the measures you went to trying to guide your C-14 with a guide scope. I know this was mostly unsuccesful. We do only...
