http://members.csolutions.net/fisherka/astronote/plan/skblnk/SketchPlanetBla... This is to announce a webpage that discusses the procedure for drafting the position of a terminator on a blank for planetary sketching either using a common Microsoft Windows tool (MS-Paint) and a Microsoft Office tool (MS Picture Manager) and by hand. The sketch blanks approximate the outline of the body and terminator that will be seen in a direct view eyepiece of a telescope tracking on an equatorial mount and where a reticule is used to indicate the direction to the celestial north pole (NCP). The terminator is pre-drafted based on a target observing date and time from ephemeris data. The hand-drawing method updpates a procedure after Sidgwick, J.B. 1971. Observational Astronomy for Amateurs. Dover. pp. 121-124. Corrections to any errors are welcomed and appreciated. - Canopus56 (Kurt) __________________________________________________ Do You Yahoo!?
