This diminutive globular is at a distance of 25,000 LY’s, which is 2.5 times farther than M 22, yet, M 22 appears 21x larger through our telescopes! NGC 6642 is not just farther away, but smaller and fainter. My latest blog has details around my observation of M21 & NGC 6642 both well down in the weeds from my 52 deg north home in the UK.
Dale,
My friend, this is a most impressive capture from so far north and with limited darkness in mid-summer.
