Further Guidelines for Marking officials ~ Constellation Mapping

 Every Team should submit at least 8 Constellation mapping reports. ( Minimum number is 8 ). If any team will submit more than 8 reports Marking officials should mark every report and SELECT 8 REPORTS THAT HAVE HIGEST MARKS for entering to the marks list.  If the observer has drawn deep sky objects such as ( Nebulas, Galaxies, Messier objects in the constellation mapping area, Give MINUS MARKS. ( drawing such like objects inside constellation mapping area is unrecognized format). But the observer can mark those Deep Sky Objects ( IF THEM CAN BE SEEN IN NAKED EYE ) by using standard symbols . Eg : - Observer can mark Orion nebula (by a Symbol) in its position ( at the constellation of “Orion”) in his/her constellation mapping drawing. But drawing Orion nebula IS NOT ACCEPTABLE !  Maximum Minus marks that can be given for each report is (-2 )  Observers should make a Relative apparent magnitude scale and show it on at least one observation report. IF it missing (– 3) marks will be added to Total marks of this session  The student must indicate the brightest star in each constellation which they have drawn.  Sizes of dots (marks ) which represent stars on the drawing is proportional to its apparent magnitude. Marking officials should specially consider about above fact  Specially consider about relative distances within stars of the constellation
