I have an Orion (Synta) 150mm MCT, and am really happy with its performance (especially) for the modest $599 price. Sure there's a tiny amount of mirror "wiggle" when focusing, it takes quite awhile to equlibriate, and it wouldn't win any beauty contests, but for a compact high-mag easy-mounter it's brilliant.
That said, there are a couple of flecks of something (pretty sure that it's flecks of blackening material used on the baffle) on the surface of the aluminized secondary spot. I would like to remove the debris, but before doing so wanted feedback from knowledgable MCT owners. This is my fourth CAT and only second MCT, and the first MCT was a 3.1" el-cheapo. It appears that removing the meniscus assembly is simply a matter of (1) marking the tube and one of the three screw holes attaching the meniscus assembly to the tube (for later orientation during replacement), (2) unscrewing the three screws, and (3) sliding off the meniscus assembly.
Is it really that simple?
If so, I plan on using a camera air bulb ONLY to see if I can dislodge the debris. If I cannot, I'll probably just leave it be.
Thanks,
Jim
