Observing Notes

Harold Corwin

Bigourdan says of this, "Very close to the star BD +29d 2357 and in the region preceding it, I suspect a trace of nebulosity, seen only when the star is hidden by the wire." He made no measurement of it, and adopted a position that puts his nebula just preceding the star. There is nothing there.

So, this is probably a case where either some optical effect led to Bigourdan's suspecting a nebula, or he was again pushing beyond the envelope of his equipment or his eyesight (see e.g. NGC 2529) leading to another
"fausse image".
