You Can't Make Stellar Images Brighter . Articles | ... Did you know that when you look at a non-stellar object through a telescope that it's usually dimmer than looking at it with your naked eye? ... The light enters the eye through the cornea and passes through the pupil which is the opening of the iris. ... Our own pupil effectively stops this large telescope to 700mm, so the image is not any brighter than in the 27.6" telescope and no brighter than the naked eye view!! ... www.astronomy.net . ...
