Obsession telescope

Original Obsession Classic 18" F/4.5 with Servocat track and goto system and Argo Navis navigation computer. Completely automated goto and tracking system. Total new price for this system is $ 10,036.

When disassembled the telescope can easily fit in a SUV or pick-up truck for transport to a dark site; the cage with the secondary mirror is placed in a custom made box for storage and transport. Setting up the telescope, collimation and initial alignment can be done in about 15 minutes.

A Dobsonian telescope is primarily a telescope for visual use. Taking pictures is possible and done; it is depending on the weather conditions; in Curaçao there is always a rather strong wind which makes it almost impossible to work with longer exposture times. Imaging the planets and the moon can easily be done by making a movie and stacking the best frames. Deep Sky Objects is not possible in Curaçao because of the wind, but I have seen images taken with this kind of telescop from other countries that are quite good. Very long exposures cannot be used because of the alt-azimuth drive system.

For a long time I am thinking about acquiring an image stabilized binocular. There is in fact only one brand that comes to mind and that is Canon. And with a short vacation coming up where an image stabilized binocular could be used for eartly purposes, I once again went searching for reviews on the Internet. That is how I found the following article. The article is already dated but still worth reading. The first part of the article follows and below it a link to the original article for the remaining part. 

In the past I hardly ever visited the website of Sky and Telescope. But with the newsfeed of the most interesting articles on this website I more often click on a link. And, when at the website of S&T, the attention is drawn to other articles. In this way I came accross the article to stabilize your binoculars without investing in an expensive Image Stabilized version.
