I reprocessed Aldebaran with ring flare so it would look similar to Spica and Arcturus.
Spica – the Brightest Bluest star in the sky. Reprocessed 22/04/2015 data taken on the Sky90 array with the M26C OSC CCDs. 33 subs at 5-minutes per sub. Spica is Alpha Virginis, the brightest star in the constellation Virgo.
From 03-06-2015 a 2-frame mosaic of Arcturus taken with the Sky90 array and the M26C OSC CCDs. Each frame was 30 subs at 4-minutes per sub. In the 5 o’clock position is the asterism called “Napoleon’s Hat”.
Reprocessed data from 09/09/2015 – the bright star towards centre bottom is Epsilon Cassiopeiae (the topmost left star in the Cassiopeia “W”) – and in the 11 o’clock position is an interesting asterism I call “Greg’s Lambda” as noone else … Continue reading
