Once I’d got the Astrotrac rather more accurately drift aligned on the final evening, we set about imaging some rather closer views of objects using longer focal lengths. This image of M8 and M20 consists of five 3 minute exposures with a Canon 75-300 zoom lens set at 180mm (f/5) and ISO 400.
Both nebulae are probably part of the same complex, some 5200 light years away and are pictured against the star clouds of Sagittarius towards the Galactic centre.
