Binoculars vs Telescopes

Posted By David Simons

Hi Craig,

For me, binoculars seem to give a slightly dimmer image, than a similar aperture "monoscope". I suppose it might be due to all the extra surfaces of the prisms, or coatings etc. I did a side by side test of a ST120 and my Vixen 20x125 bino's at about the same power, and the the lowly ST120 actually gave just a slightly brighter image, with a hint of more stars. But the easthetic view in the bino's was a whole different story. The stars seem to come alive, star colors were more obvious, and nebula seem to stand out in front of the dimmer background stars. It was so dramatic, the ST120 was not used the rest of the night. The large open winter clusters really emphasized this effect. Orions nebula was ... well I could go on. : )

Hi Dave,

Any suggestions on aperture or power for most of these objects?

David,

Big question is do you have or can reasonably get to dark skies?
