DIY tilt adjuster and first test

Well, I tried to use the Orion SSAG mono imager with the PST. VideoSky worked pretty well, but in the end it wasn't meant to be. The images were plagued by a nasty interference phenomenon that occasionally rears it's ugly head with h-alpha imaging. It is known as newton's rings. Common thought is that it is a form of optical interference with the light bouncing back and forth between parallel surfaces in the optic train. The usual cure for this is rotating the imager in the tube. For more severe cases, a slight tilt off-axis is required. I cobbled together a homemade tilt unit and gave it a shot. Here is the tilt unit I made..

The tilt is controlled by three screws. Pretty simple design, actually. Unfortunately, testing this morning proved that no amount of rotation or off axis tilting would cure the dreaded interference. Newton's rings were still present in the image. See below:

The light area at the top of the screen is also a result of using the videosky program. I couldn't get rid of that either, no matter what camera setting I used. I hate to admit defeat, but using the SSAG camera is a complete and dismal failure with the PST. Researching the problem online shows that this problem is quite common with monochrome imagers with the Micron chipset. The interference seems to be native to the chip itself. Unfortunately that means that there isn't a dang thing I can do about it. Time to save up for a DMK21. Back to the drawing board...
