United StatesWhen the Artesky Flat Field Generator was first turned on, I observed that it had obvious defects in the light field. I will be exchanging it for a replacement. The unit itself seems very sturdy and should work quite well with my telescope provided I can get a replacement with no irregularities in the light field.
United StatesIt is well made, with one exception. When turned on, two line shadows appear going from the outside edge to the center. They are caused by internal power leads that have deformed the foam backing which cause shadows. I was hoping to re-route these outside of the flat to the power supply, but couldn't get to the connections on the power supply box. I hope that when the scope is at infinity focus, these will blend, but it is a bit troubling.
