Quote:Andy, when the edges on the stacked show a shadow, it is usually from poor unstable seeing. If you drop to the smaller barlow and increase the frame rate to 15 or 20, you should be able to freeze the seeing better. Not sure about your setup, but I would recommend at least 2hrs of scope cooling with fans directly blowing before imaging.Regards,Steve

Quote:Alright, you said it was a problem that is thought impossible, but needs to be on the list of possibles...I'll go with my wife's suggestion...double exposure. Hey, I'm a believer in Occam's Razor.
Quote:Very interesting, Andy. I have often wondered if filters get slightly tilted. Or, the possible effects if filters are stacked in the optical train. I've considered light reflecting off filter and CCD for bright objects, like the moon or sun.Since you work with video and the optics, I wonder if you would know why I got these patterns in my images taken with an older planetary camera, DMK31. It seemed to occur when pushing the image size with C8 + 2x barlow + FW + camera, adding extension tubes to get to f23. As I increased image size and gain to make up for dimming, the pattern appeared. TIS reps said it is Moire. But, I don't know how I can get Moire.Here is an example:
