Nice picture, crisp and detailed.. from corner to corner.
BTW, you have a typo near distance din description:
"
M 2 is a globular cluster in constellation Aquarius. Distance 36 lys, diameter 150lys"
Should be 36 klys ?
(quote from Wiki : M2 is about 37,500 light-years away from Earth. At 175 light-years in diameter)
