If you cannot get your arm past, holding a suitable ring spanner, I suggest you remove the spider rather than removing the primary. Unless you think your primary needs a wash - then remove it instead and do two jobs.

Nah, I couldn't quite reach through with the secondary still in place, at least not without knocking it around a bit, which I figured would be just as bad as taking it out. I'll give that a go tonight -- hopefully it doesn't put my collimation out too far. Might be a good excuse to finally pick up a collimation tool and learn how it's all done!

Ah, that's excellent advice! I hadn't thought of that, and knowing me, that's exactly the kind of thing I'd do. You probably just saved me the cost of a new primary
