is pleiades possible w/77x mag?

Is the entire pleiades possible with 77x mag if one has a really wide fov?

Well, the furthest distance between the seven brightest stars is a tad over 1 degree (Atlas to Celaeno), so theoretically an 80+ degree FOV will show you - very barely - all seven sisters, with four of them at the very edge of the field.

So, a Nagler may just do it if you can find the right one for your focal length
