oag vs guide scope
Advantages of Off-Axis Guider. OAGs avoid the problem of differential flexure since there is no separate guide scope on an independent mount. OAGs result in one less telescope to be handled by the mount, and require a simpler mounting system overall. Placed before the filter wheel, the OAG deflects unfiltered starlight,
18 May 2017 In this entry I would like to compare off axis guiding (OAG) with guiding using guidescope. These two are probably the most popular Off axis guider mounted in the optical train with coma corrector, ASI120MM guide camera, Atik filter wheel and Atik 383 camera. In off axis guiding in the main optical train
I'm an SCT owner with an off axis guider - I'd at least learn to be patient with it - the long focal ratio doesn't give you much of a chance in finding a guide star. Don't know what . Now he's just running the same 50mm finder scope package he has on his refractors and able to get 10min subs tracked w/ it. Not sure if he tried to
35mm film astrophotography requires long exposures, which usually requires correction of There are two ways to manually guide a scope during astrophotography: with an off-axis guider or with a guide scope. Click on the Guidescope vs. 26 Jan 2014 We were initially going to go for an off-axis guide Package, which
23 Oct 2015 Dear Guylain, I am looking for some professional advice, from you or anyone else who has used either an off axis guider or guide scope, or both. Which would
20 Jul 2017 A separate guide scope and guide camera; An off-axis guider that splits off light collected by the main telescope, but which directs the light to a separate guide camera that detects a guide star somewhere in the same .

31 Aug 2010 my equipment: celestron 8 inch SCT on a CG-5 what are the advantages of buying a small guidescope to attach as a 'finderscope' to my C8? seems like having a second scope might be pretty convenient. HOWEVER, it seems 'easier' to just use an off-axis guider with a reticle eyepiece or guiding camera as
I suggest a guide scope. OAG works great at long focal lengths but is better with large apertures and very sensitive guide cameras. I suggest the Orion mini autoguider package I've used to happily guide a 2m scope though these days I use a focal reducer and am shooting at closer to 1250mm (very close to
26 Jan 2014 I then came across the Orion Magnificent Mini Autoguider Package, which looked like good value. My understanding is that it would not be suitable for our f/10 8" Celestron EdgeHD OTA because of its long-ish focal length. I read that the guiding scope should have a focal length of ideally no less than a fifth
Autoguiders. An autoguider is an electronic tool used in astrophotography to keep the celestial object being photographed from drifting across the field of view. When you aim your telescope outside the solar system – at nebulas, star clusters, and galaxies – exposure times increase dramatically. At these settings, even the
