The contestant should use the finder scope to mount the object in the visual field.

The object must be located in the center of the crosshair in visual field.

The contestant must mount the object within 2 minutes (Maximum)

5. Marking Scheme for Constellation Mapping Session

Every Team should mention following details on every Constellation mapping report which they are submitting to the Academic committee for marking.

Detail Description about the detail Marking Officials Guidelines

Marks

Name:

Name of the student who made the report

Location:

(Kandy ) or (Peradeniya) , Sri Lanka

No marks without “Sri Lanka”

Date : 16th of February 2018 In any format

Start = ………………….UT Finished = ………………… UT

No marks for LCT time format

Mapping Scale 1cm = ……. degrees

Total Marks for each mapping

Report =

( 20 + 8 ) 28 Marks

5.1 Additional guidelines for marking officials ~ Constellation Mapping

Every Team should submit 5 Constellation mapping reports. If they have submitted more

than 5, mark the best drawn 5 only.

If the observer has drawn deep sky objects such as Nebulas, Galaxies, Messier objects in

the constellation mapping area; Give MINUS (-5) MARKS. ( Drawing such objects inside

the constellation mapping area is not acceptable ). But the observer can mark those DSO

using standard symbols ( If these objects are seen via naked-eye ) .

Eg : - Observer can mark Orion nebula (using a Symbol) in its position ( at the constellation

of “Orion”) in his/her constellation mapping drawing sheet. But drawing the Orion nebula

IS NOT ACCEPTABLE !

Observers should make a relative apparent magnitude scale and show it on at least one

observation report. IF it missed ( – 10) marks will be added to Total marks of this session.

[They should consider Vega (alpha Lyrae) = 0.0 ].

The apperent magnitudes of each star should be represented by the size of the “dot” which

represents the particular star in the report.

Sizes of dots which represent stars on the drawing sould be proportional to its apparent

magnitude. Marking officials should specially consider about this fact.

The student must indicate the brightest star of each constellation

Specially consider about relative distances within stars of the constellation. Relative

distances between each dot shoud represent the angular separation of respective stars of

the original constellation in the sky.

The marking examiner should pay special attention on “Drawing arcs” which was used by

the observer to map constellation. If there are no such arcs visible on the report, Give

MINUS Marks (-10) to such report.

5.2 Distribution of marks for Constellation mapping round :-

Marks for one report
