Three section members contributed this month, a total of three digital images and a written report.

David Davies imaged two galaxies, M61 and M58, which are both in the constellation of Virgo:

M61

M61 is considered to have a 5 million solar mass black hole at its centre, and is categorized as a starburst galaxy with considerable new star formation evident, plus eight supernovae recorded in under a century of observation.

M58

David used a 200mm Richey Chretien telescope with a ZWO ASI 294 MC Pro colour camera for M61 and a QSI 683 mono camera plus red, green and blue filters for M58.

 

Mark Beveridge used a Celestron C11 SCT at f22 and ZWO 385 MC colour camera to image double star HP 59017 in the constellation of Ursa Major, taking videos of the star and stacking the best 15 frames out of over 11,000 frames in total:

HP 59017 is a pair of magnitude 7 stars with a current angular separation of 0.33 arcseconds.

 

Chris Laming, a new section member, enjoyed clear skies from his dark sky location in the Forest of Dean to observe globular clusters M13, M92 and NGC 6229 and double star Rasalgethi (Alpha Herculis) all in the constellation of Hercules, also M57 the Ring planetary nebula in Lyra.  Chris used a Celestron Nexstar 8SE and a variety of eyepieces.
