Messier 44, an open star cluster that can already be seen as a nebula in the evening winter and spring sky
This star cluster is the second brightest star cluster in the Messier catalogue after the Pleiades and stands out in its position because there are no stars brighter than 4th magnitude in Cancer The distance is 577 light years, the diameter is 22 8 light years

There are quite a few versions of the Crescent
nebula in the net Here is my (new image processing) version and compared
to the Hubble range of the Nebula (NGC6888in Bicolor,
Distance 4 700 light-years) Ha-Alpha for red
and [OIII] for green + blue
Exposure 16 x 1 200s for [OIII] + Ha-Alpha
Ha-Alpha = hydrogen line, [OIII] = oxygen line

Hi folks,
the sky above the observatory at the winding tower last night:
I wasn't expecting that this could be observed at all here, especially as the sky was quite poor in terms of transparency and contrast

It's a real pain to complete the Messier catalogue if you don't keep at it I've been tinkering for about 24 years now, every now and then, to get the catalogue complete and have only managed just under half of all the objects The globular star cluster M56 will now be a further addition to my Messier catalogue and also another diamond in my KH collection

At a distance of about 30,000 light-years, M14 contains several hundred thousand stars At an apparent magnitude of +7 6 it can be easily observed with binoculars Medium-sized telescopes will show some hint of the individual stars of which the brightest is of magnitude +14
