A framing of the group of large binocular-class star clusters in Serpens and Ophiuchus: notably, the pairing of IC 4756 (left) and NGC 6633 (right) at upper left, sometimes known as the S-O Double Cluster, or Tweedledum and Tweedledee (really!), and the cluster IC 4665 at right above the bright star Cebelrai, or Beta Ophiuchi. At centre is the V-shaped asterism known as Poniatowski's Bull, from a defunct constellation created in 1777 by polish astronomer Marcin Poczobut to honour the king of Poland at the time. The grouping is also catalogued as Melotte 186 and Collinder 359. The asterism was marked as a constellation on Bode's Uranographia star atlas of 1801. The bright star at upper right is Rasalhague in Ophiuchus. This is a stack of 8 x 1-minute exposures at f/2.8 with the Rokinon RF85mm lens on the Canon R5 at ISO 800, blended with a single exposure through an Alyn Wallace/Kase StarGlow filter to add the star glows! The camera was on the Star Adventurer tracker. Taken from home Sept. 25, 2022.
A very wide angle image of the northern summer Milky Way from Cepheus (at top left) to Sagittarius (setting at bottom right), with the Summer Triangle stars at centre. The bright object at bottom left is Jupiter, with Saturn dimmer to the right at bottom centre. This is with the TTArtisan 11mm full-frame fish-eye lens wide open at f/2.8, in a stack of 7 x 4-minute tracked exposures at ISO 1600 with the Canon EOS Ra camera. Taken from home July 8, 2021. No filters were employed here.
