Introduction of easel constellation

The picture frame of this painting is located in the southern sky, in the south of Pigeon, between large magellanic cloud and Carina. The best observation time is 65438+ 10 month, but the stars that make up this small constellation in the southern sky are very dim and hard to see on the earth. For observers with only small telescopes or binoculars, this constellation may have nothing interesting to see. The brightest star is Alpha, with an apparent magnitude of 3.30. Other famous stars are:

Draw a constellation, which is a binary star. The two satellites are +5.5 and +6.5 respectively, with a difference of 12.3 arc seconds.

Draw a picture of beta star. This +4-magnitude star has no features. It is the first time to find a protoplanetary disk made of primitive matter around it-it may be described as a planetary system in the near future, but it is impossible for professional astronomical telescopes to see this disk.

Kapteyn is a red dwarf star with a magnitude of +8.8, which is 2.78 light years away from the sun/kloc-0. It is second only to Barnard in Ophiuchus at a speed of 8.7 arc seconds per year.
