yesterday, I cleaned my d800 sensor, mirror, eyepiece etc. When I look through the eyepiece I see what looks like a dust spot that I cant get rid of. It does not show up on the pictures. The only thing I can think of is that it is between the eyepiece and what ever is next in the chain ant ideas on how to get rid of this?
It could be on your mirror. Try using a rocket blower to blow out the camera inside, mirror down, not locked up like when you clean your sensor. Do not touch the mirror. If that doesnt do it..and it doesn't show up on your photos.. Learn to live with it. A camera that gets used is a camera that will pick up some dust in places you cannot get rid of it.

It's probably on the top of the focusing screen which is just below the bottom of the prism. You'd have to remove the screen to get at it, most likely. Spots on the mirror are that visible plus it's best to leave it alone as far as cleaning.
Dennis - If you can see the dust spot though your viewfinder, it is NOT on your sensor. If it is in sharp focus as you loo at a subject, it is almost certainly on the focus screen. I'd try a puff of air from one of the devices designed to apply air to the inside of a camera -- like the Giottos Rocket -- with the lens removed. You may in fact, be able to see it if you turn the camera body upside down an shine a light into it an look toward the focus screen/prism. Do NOT use compressed air or your own breath. Compressed air propellant can be too powerful and may contain oil. Your breath may include spit!
thanks for the comments Alan and Alan. I have used the air blower in an attempt to clean it with no luck, I also believe it is on top o fthe focusing screen.
I chuckle when you mention the Giottos Rocket, I have one, but I was traveling and forgot to bring it. I was in Quito Ecuador and was bent on cleaning the camera to rid the sensor of dust and this is when I noticed the spot. I decided to go get a Giottos blower or somehting similar. After going to all the camera stores in Quito with no luck (dont know how they clean their cameras in Quito). I was finally directed to the Botica Alemana which is a pharmacy. Believe it or not, that is where I was able to buy one. These guys also sold a lot of lab equipment. They were called Peras de Goma (rubber pears). Anyway, if you are ever in Quito Ecuador and need a blower, there is the place to go

Dennis - Thanks for letting me know where to get a "rubber pear" if I'm ever down Quito-way! I guess your options are to pay the freight to get the thingy removed or to learn to ignore it! How utterly frustrating! Sorry. My latest frustration? The day before my second D800 arrived, I fell and tore my rotator cuff. I have 4 more painful, post-surgery weeks in a sling, before I can even open the box. I sure hope there's a camera in there!
I too now have this problem. On a road trip with my family and have been changing lenses like crazy. I cleaned my sensor and mirror with the rocket blower and blew a speck onto my focusing screen. I am fairly certain it is trapped on top of the screen under the prism. Although I got rid of my sensor spots and now have spec free shots, this little speck bugs me. I'm too chicken to remove the screen though. I guess this is the better problem to have.
