Does anyone make a skylight filter for the 3.3" thread on the back of my C11? I know I could screw a 2" filter on the back of my reducer, but I'd rather eliminate one more in-line adapter since I'll be placing a JMI focuser with 3.3" threads just behind the SCT rear cell. I need the filter strictly as a dust block. Any help would be greatly appreciated!
