By constellation:



The Coathanger (Asterism)
Also known as: Collinder 399 (CR 399), Brocchi's cluster
Right ascension: 19h 27m Declination: 20° 09'
Constellation: Vulpecula
Date/time: 2009.06.19 21:00 UT
Equipment: 10x50 binoculars
FoV: 3° 30' Magnification and filter(s): 10x
Seeing: 4/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This famous cluster demands a huge FoV, that can only be achieved by binoculars. At a NELM of about 5 magnitudes, you may notice it with your bare eyes as a large, diffuse spot. The coathanger shape is formed by 10 shiny stars, and the background is painted grainy by the Milky Way.

Lovro 2 (Asterism)
Right ascension: 0h 22m Declination: 24° 50'
Constellation: Hercules
Date/time: 2009.09.16 00:00 UT
Equipment: 12" f/5 Newtonian
FoV: 1° Magnification and filter(s): 71x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A fairly large asterism made up of stars of similar brightness and colour. It clearly separates from its environs, however it is only an asterism and not an open cluster according to the data I could put my hands on. It resembles either a double questionmark, or the flames of a large torch. Sofar I couldn't find any catalogue that listed this object as an asterism, so I decided to use the designation of Lovro 2. However, please not that this is a totally unofficial designation.

Appeared in Sky & Telescope 2013/01.
