There are two main sources of light leaks on the 200PDS: * The primary mirror cell: you can fix this by buying a large black shower cap from Amazon (cost around $8 or £8) * The leaks around the edge of the focuser mount: easily fixed with black electrical tape (cost minimal) Just thought I'd share because once done you can take LED flat panel flats when it is still light. Also, it means stray light won't affect your images so much. |

Same issue with the primary mirror cell of my Quattro. I wrapped around a black garbage bag ! Philippe |
