It should be noted that the 3-5 foot dimension for the telescope Messier mentioned was the focal length of the telescope, not the objective diameter.
It is thought that his telescope was the equivalent of a modern 4-5 inch telescope.
M27 is the first planetary nebula discovered. It was discovered in 1764 by French comet hunter Charles Messier.
Messier noted:"Nebula without star, discovered in Vulpecula, between the two forepaws & very near the star 14 of that constellation, of 5th magnitude according to Flamsteed; one can see it well with an ordinary telescope of 3-5 foot; it appears of oval shape, & it contains no star."

A new impact flash has been discovered on Jupiter by Brazilian observer Jose Luis Pereira - the flash occurred at Sep 13th, 22:39:30 UTC. It looks quite a bright one. Follow up images of this region will be useful to see if any dark scar was left following the event."
