Many of us guide with a 400mm refractor and are switching to this excellent guide camera. It would be great if you could provide a good starting point for the camera settings. I only had one try with the camera as a guider so far. The image was noisy and guiding was problematic - the corrections did not seem to be working even though the calibration was perfect. I could use help on knowing the best settings for the camera. I used the settings that were already on the camera, including RAW 16 manual gain=200 Offset=90 USBLimit=40. I later noticed a warning that 'Guiding won't work under RAW16', which may have been my trouble. Can you provide a starting point for these settings, please?
Thanks

Try this: RAW8, Gain=189, offset=90, USBlimit=40
The noise will reduce a lot when you on focus point, if there is no stars on screen, noise will looks much, because the auto-strength of histogram.
Thanks! I will give it a try.
By the way, what does the Raw16 setting do and how does it make guiding go bad? Can you explain this for me?
Thanks,
I'm not sure why 16bit is not good for guiding, it looks like a limit of software, 8bit depth is good enough for guiding.
Hi,
Usually, the image of the guide is discarded after use. Therefore, we wanted to give the main camera enough resources. That means 8 bits is enough, so you don't need 16 bits to take up bandwidth.
