Problems with my ASI 2600 MM Pro?

deebbecke

Last night marked my 3rd night out with my new 2600MM Pro. During each night I've had issues with what appears to be condensation

First night: I made the following post. Chalked up up to failing to switch on the camera's dew heater. Prior to going out for a second night I inspected the sensor (removed EFW) and it was spotless.

Second night: Started off with similar issue but different pattern in the image. Camera's internal dew heater on the entire time. The issue seem to resolve rather quickly. I didn't get any images from the second night.

Last night: 30 minutes prior to imaging I set up the scope. Temp:40 deg. F. When I was ready to image I switched everything on and noticed the same issue, however this time, the problem worsened over the next ₁ hour until I decided to end the evening in frustration. Camera cooling set to 0 deg. the entire time. It was approx. 38 deg. F when I started imaging and 35 deg. F when I quick after about an hour.

Below is the progression.

Do I have a problem with this camera or is it me? Looking to the collective wisdom of other. Thank you!

Try not using the camera dew control. I never use mine and just use dew heaters on the scope.
Are you leaving the camera attached outside or letting it cool outside before turning it on? If so it might be an issue with a cold front glass that when heated up, it fogs up and takes a long time to remove the fog that is created while heating it up. If you are bringing the camera inside then that is a completely different story. It depends on what temperature your camera is at when starting it up…. Warm or cool. Try starting the camera when you take it outside and not use dew control… let the electronics heat everything up for 30 minutes or so before imaging in cold weather.

I start my asiair up 1 hour before imaging in the cold. I turn on the dew heaters on the scope and have never used my camera heater as the sensor heat is enough. I also just added a dew heater on my flattener too… on low just to keep it ok at -10c outside.
