A very transparent sky and dead calm on 2nd-3rd October was an excellent opportunity to catch up with monitoring Variable nebulae and related objects. Four objects were imaged as follows:
Gyulbudaghian's nebula in Cepheus is always top of my list for imaging each month. It is still faint and shows just a narrow bar of nebulosity.
Hind's variable nebula in Taurus (just north of the Hyades) is a bright knot of nebulosity very close to T Tauri. Both sit in a void in a much larger diffuse nebula.
FU Orionis sits in the dark nebula Barnard 35 at the top of Orion. Rising from mag 16 to mag 9 in 1937 over just 3 months it remains near mag 10 today. Some nebulosity is visible close to the star today which was invisible before the star brightened.
McNeil's nebula remains invisible in images of M78. Some image artefacts appear at the position of the nebula but I'm sure it isn't there!
