I am specifically talking about not returning to guide star. I made some progress by measuring the backlash in PemPro, then using those numbers in the INDI driver for EQMod.. The guiding software itself seemed to work ok once I used the larger backlash numbers. My backlash was measured at 770 msec which is huge in my mind. It is a EQ8 mount which is not know for tight tolerances. I am just saying, if Kstars had a tool like PemPro to measure backlash, I could have gotten to the solution faster... For example, this would mean moving the mount in one direction, say for 1 second (larger than most backlash measurement), then one second back the other way . The second pulse wont get you back to the star, but incrementing the back step until it does with the difference between the two directions becomes the backlash measurement. Just my thoughts....

I know this topic of failure to reach original star when guiding calibrating has been discussed several times. I recently went through this with great difficulty to resolve. I finally got a working solution that I would like to see integrated into Kstars as a tool. I went back to a windows tool Pempro which has a backlash measuring tool. Measured the backlash and entered into the indi driver for success. I also know the mount is long in the tooth for a tear down and cleaning so there may be multiple issues at play here.... I don't think I am a 1 off user here. Thanks for your consideration on this issue.... Bruce

Thanks for the response. I think I am getting close to solving this. The RBPI4 I used was an early model. I tried switching to a smaller camera QHY163, which worked but it struggled. I then replaced the RBPI with another RBPI 4, I don't know if it is the newer version but it seems to be working. I have not done a full blown test yet, because I have take my equipment apart to replace the PI. This looks look a PI limitation and how big a frame your working with. More testing to come.... Bruce

Kstars keeps crashing and no log files are being written. It seems to be crashing when saving the fits file. There are no fits file being saved either. I am using a QHY128 full frame camera on a iOptron ZEQ25. The indi drivers seem to start just fine. All software has been updated and upgraded using ubuntu command line.

Thanks for looking Bruce

I am looking to set up a cpc11 for remote operation. Currently the hand controler needs to have the enter button pushed to intialze the scope. Has anyone figured out how to remotely run the cpc1100?.... Bruce

The image looks like a lot of noise which is not normal for Sony CMOS cameras. To me it looks like very low gain with extreme stretch... I am the US distributor for QHY cameras. Bruce Morrell

Did you set your gain to about 1000 or more? Unity gain is 3200, which is too high given the dynamic range. The dynamic range on this camera is relatively flat with gain settings out to 2500. Bruce

20 second download is normal for a un binned image. No clue on the debayer error. I use EKOS only to capture the image, not debayer. The software would have to know what the bayer pattern is to be able to debayer it. .... Bruce Morrell

Thanks Jasem,
I must have missed it, where do I find it?? I really need it for the focus fits, because that's where I have the biggest need?? Is it customizable? I want to be able to see the stars quickly while I am busy focusing .... Bruce
