MARCH 29TH / 30TH - BARKERS QUADRANGLE OBSERVED

[paulastro]

I was out from 11.30pm on 29th until 1.00am on 30th with the Tecnosky 102ED F7.  The seeing was very poor, but it was clearly visible in moments of better seeing when it would pop into view.  I used the binoviewer, x2 barlow and 24 and 16.8 Orthos.

I took many single frames, and the frame below was the best of the bunch.  Taken at 23.57pm on 29th with the Olympus E-M5 Mk11 on 1/400 at 200 asa.

There are two crops from the same frame, necessarily over prossessed to shop up Barkers Quadrangle.  I've also added the drawing (inverted) by Nigel Longshaw from his article in the Feb edition of Astronomy Now.

Spotted the Quadrangle just now with the mighty Heritage 130 P Flextube at mag 183x.  A clearly outlined irregular trapezium (more a rhomboid) with borders most distinct in the NW part, and extending here in a kite's tail. The SE and SW corners not fully closed. Clearly composed of lunar ridges. The "kite"  shape is distinct and rewarding; saw it for the first time; thanks for the heads up.

Just adding my picture from Monday night to this thread. Was a fun feature to hunt down. Thanks for the heads up
