Guide Scope To Main Scope Ratio Joined 20 Jul 2007 Posted 23 July 2012 06 28 PM I use a 50mm f 50 MiniBorg with an ATIK Titan camera to guide at 6 1 image scale MY imaging scope is a TEC 140 F 5 4 and the image scale is 1 5 and it guides very well But the mount must also be able to guide very well for any guider to really work
Off Axis Guiders are typically used with dedicated astronomy cameras and are placed inside the imaging train itself These do not sit on top of the scope like a traditional autoguiding system would Off axis guiders use the main imaging scope to direct light to the guide camera rather than a guide scope A small prism drops down from the OAG This ratio is based on the ratios of the main and guider sensor resolutions in arcseconds this means it uses both the focal lengths and the imaging sensor pixel sizes This is more like it as means an auto guider with small pixels does not need as long a focal length guide scope as one with big pixels The G ratio is defined as

The guide scope is just what it sounds like it is a separate telescope with its own camera dedicated to the role of guiding This second telescope will typically sit on top of your scope or on a bracket mounted to your scope The off axis guider is a device which sits in your imaging train between your focuser and your camera and before

Depending on my main guide scope camera combination I have a ratio of anything between 1 1 37 and 1 5 43 and I don t seem to struggle with guiding or more accurately poor images related to guiding as a result of the higher figure

The guide scope s job is to provide an adequate field of in focus stars so the autoguiding camera can find an appropriate candidate for calibration and guiding Guide scopes are often inexpensive simple telescopes ranging from 30mm 60mm in aperture In this article I will provide tips for choosing a guide scope for autoguiding

Guide scope and camera on main telescope phd2 autoguiding software Most guide cameras have an F ratio of about F 3 to F 5 The F ratio is simply the focal length of your telescope divided by the aperture So if we take a focal length of 150mm and divide it by 3 a good aperture would be 50mm Again these are soft rules of thumb to get you

Guide scope imaging scale posted in Beginning Deep Sky Imaging This may have been covered in older topics but they seemed to have focused on focal length ratios between main and guiding scopes and not on image scale ratios of same At my most aggressive scale Im imaging at 0 95 sec pixel OTA has a FL of 825mm attached camera has 3 8um pixels
3 Aperture and Focal Length of a User Scope Several factors real trade offs make for a good guidescope for astrophotography including AMPERE sufficiently large hole to detect faint guide stars in a nearly any field from view somewhere in the sky and until minimize autoguider exposure time nevertheless a small enough size and influence to avoiding taxing the mount Ideal focal length to guide When setting up a guide scope the main consideration is the comparison of the pixel scale of your imaging rig compared to your guiding rig The pixel scale is just 206 pixel size focal length Assuming your 30 mm guide scope is f 4 that would be a focal length of 120mm Using a common guide camera such as the ASI120MM which has a pixel
