Here is one exposure taken last night of M8.

Take 1000 of these over 4 different nights, discard 800 because of periodic errors in the drive, stack the remaining 200, process out all that brown light pollution, and...

WALLA! You have yourself a picture. 

This is a nearly full frame, and it shows one of the features of a reflector telescope. The further from the center of the image, the more the stares are flared on an axis coming from the center.  For centuries, telescopes have been a collection of compromises; one has to choose which set of drawbacks one is willing to accept to get the features they want. Newtonian reflectors have a lot of coma (that flaring effect) but can gather more photons per dollar than any other design.
