orion 16 inch dobsonian review

The scope can be completely disassembled and transported. Automatic tracking also enables you to have a go at planetary imaging using a video camera attached to the focuser. Total time for tear-down and setup is about 25 min. Next, take lots and lots of subs! It is important to note, field rotation, generally speaking, is not a problem between exposures. Image 1 shows the effects of field rotation. But most importantly, develop your own! Keep at it! I own an Orion 16-inch GoTo Dobsonian and as the name implies, it is a standard GoTo scope with the type of hand controller most of us are familiar with. Generally speaking, the maximum exposure time to minimize and overcome the effects of field rotation is 30 seconds. You can do this by visually aligning stars within the field of view. Note their reaction. If that is the case, then we could call any type of scope (Mak, refractor, SC, astrograph) mounted on an alt/az mount a “Dobsonian.” The point being, the terms “Dob,” “Dobsonian,” “alt/az mount,” are all, generally speaking, synonymous. A lighter, less overly robust head would have eliminated this task and saved further weight. And, of course, the sizeable aperture gave great views of deep-sky objects, including the Orion Nebula with its bat-like wings and the sweeping chains of stars of open cluster M35. Probably first and foremost, and the one most AP hobbyists are familiar with, is field rotation. Is it possible to auto guide for longer exposures? I spent countless hours during many summer nights looking up at the night sky. For DSO processing, I use Nebulosity to review and toss out bad subs. If we could track Orion the entire day, we’d see him rotating 360 degrees in a 24-hour period. Refer back to your first sub and compare it to the most recent sub. First, what is AP? With excellent light grasp, point-and-view ease of use, convenient portability, and a low price, the XT6 Classic Dobsonian reflector should be on the top of any beginner’s telescope wish-list. The Go-To made viewing the centre of the Virgo Cluster a pleasure rather than a chore and then drove us on a short distance to view the faint but wonderful razor of edge-on galaxy NGC 4762. I think part of the reason is the “hunt.” Knowing an elusive and difficult target is out there and we hope to capture it on “film” drives us into the bitter cold night after night. That, my friend, is how it is done. Now, rotate your camera such that the live preview (or a test sub) closely matches the first sub taken. To minimize tracking errors, I like to shoot no greater than about 50-60 degrees in elevation. Hopefully some of the mentioned tricks and techniques will help you along the journey. The tracking and GoTo capabilities are not unlike other mounts. Notice I said “their limits.” Scopes don’t necessarily have limits, people do. I occasionally use Topaz for additional noise reduction. But I also think we are motivated by the following: sharing the love and fascination of the hobby with others. The basic subject, in this case Orion, is certainly discernable, but there are way too many “left overs” for this to be a good photo. So, what makes a Dob a Dob? The telescope has a 16-inch primary mirror with enhanced reflectivity coatings, as well as full Go-To capability and motorised tracking.
