Description

Like everyone suffering from bad weather season for weeks, I was more than lucky to have two nights for imaging. The Leo Triplet was the second target in that two nights. At extreme cold (down to -15 degree) the cooler of the camera was at 1%. Dealing with ice on the gear was a challenge. I am very happy I can control everything from the office - except putting the flat field on and off, which was no fun at all .

Thanks for enjoying the image!
