Hi. Donna. The SBIG STF-8300 I received was well received. However, after receiving the product, the weather in Korea was not good and I could not go to shoot pictures. Then, last night, the weather was so good that I took a photo shoot. But I could not take pictures. Because an abnormal phenomenon was found in the ccd, I could not proceed to shoot any more. The reason for this is that when I look at the picture file attached, the cooling device of the ccd does not work, so the temperature of the ccd has risen by as much as 135 degrees and I was afraid that the ccd would burn. I think there is a problem with the product itself. What I want to do is pick up this product and then exchange it with a new one, or if you have a dealership you want to repair quickly. However, all the costs associated with this will be borne by the seller. Please contact.
