Historical observations
John Herschel
Discovered by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "very faint, elongated, gradually brighter in the middle; with a feeble appearance of stars, but I have hardly a doubt of its being a nebula."

12-inch f/10 SCT (95x 218x 346x)
A faint smear light. Higher magnification brings to the fore an elongated brighter ray of light in a north-east to south-west direction. With closer investigation the north-eastern edge seems somewhat fatter with a slightly broken middle that tappers down to a south-western tip. Averted vision lifts it out beautifully against a rather busy star field, just 55’ north-west of alpha Apodis
