Two eyes sees better than one In this post I will look a bit into the subject of Bino viewing. By Bino Viewing I mean any solution where the observer uses both eyes when observing Binoculars Bino-viewers – Beam splitting device installed on a single telescope Bino-Scopes – Two identical telescopes installed in parallel The post will touch the following subjects: The advantages of observing with two eyes The bino-viewer The bino-scope Telescope Mounts for Bino Viewing The advantage of observing with two eyes Relaxing and easier to see small details Observing with two eyes means that both eyes receive the telescopic view of the object. This is how our eyes are meant to be used, so it will for most observers feel more relaxed and natural. Small details hardly [...]
The winter sky with the many gas nebulas has disappeared in the western twilight. In an earlier post – Fast Deep Sky Imaging – I described how these large objects could be imaged with fast optical systems with limited focal length and large field of view. In springtime our view points away from the milky way arms and we get a free look to myriads of distant galaxies. Observing and imaging galaxies is a quite different matter as you can read in this post. Galaxies and dark sky For most unskilled visual observers Galaxies are faint hazy spots. If you try to observe galaxies from a light polluted place and don’t give you the time it takes to learn to really see these faint objects – all you will see [...]
Below is the slides from a presentation I have held several times at different Starparties. The presentation gives a basic introduction to eyepieces and how to select the right ones for your telescope.
