I managed to pinpoint and image the craterlets Armstrong, Aldrin and Collins located in the North-East Quadrant, East part of Mare Tranquillitatis, using my 201mm dia. f/11.5 telescope from my back yard in Brisbane, Qld, Australia on 19th July 2019 at 00:55 am AEST.
The atmospheric conditions (seeing) were not ideal so image quality has suffered from the jet stream turbulence. The lighting is quite flat as the time was just after Full Moon.
At the time, our Moon was 396,730 Km from the Earth with an apparent diameter of 30.12'. The Lunar Phase was 340.8°, Lunation of 15.82 days and 97.2% illuminated.
Reference data from the “Virtual Moon Atlas”.
