I think that's Saturn coming into ascension. The darker bit below it is the moon waxing...
HTH
looks like a dust spot on the viewfinder - the sharp focus suggests to me it's there rather than further down the way.
Or, it could be something designed to show you the location of the upright - i.e. that's the dot on the centre line, given that the split focus screen runs at 45 deg
its dust, don't bother trying to clean it.
I will not effect your pictures
Compressed air can - remove lens (if possible) and open the shutter - give it a blast from the air can and hopefully it will remove the dust particle.
I'm not photographer but I've seen that done...
It is muck on the focus screen , the screen the mirror reflects the image onto.
If it is on the outside - most likely - then you can easily remove it.
Take the lens off and turn the camera upside down - the white/gray screen should be obvious.
Do not rub the screen as depending on the design you will find that the
screen is rough/machined on the side you can access - flick the lump of dirt off with a lens brush or similar.
Note that as it is a biggish lump it may be part of the mirror buffer foam degrading - hence do not use a powerful air blower as it will send bits everywhere including the shutter - which could kill it.
Some cameras have removable fucus screens - but not yours.
Thanks all.
I've put some film in and fitted a 28-70mm lens. I'm good to go.
Lock and load.
A goose feather (seriously) is probably the best thing for cleaning dust off focusing screens. They have a slightly "sticky" feel (because of the microscopic bards) which seems to grab hold of the dust better than a brush.

@Dick Barton - you can't clean screens with the shutter open as the mirror will then be obscuring the screen.
