Last night I took some images of the Aldebaran field [below] and comparing them to Wikisky DSS2 for stars mags.
On Wikisky I noted a circular and evenly illuminated but faint disk-like object ~22"-arc in diameter in the glare of Aldebaran. It's located 9'-arc Sf Aldebaran @ RA04 36 30 Dec+16 26 03 [2000.0] and looks like planetary nebula with central star ! There are many faint galaxies in the field too at ~m15 and fainter.
A check of POSS1/2 blue/ red plates and Hubble images all showed the same object at the same location which ruled out an artefact from Aldebaran or cometary in nature. A Google search by myself and a deepsky observing buddy both drew blanks - he thought it may be a galaxy but I still favour a PN. This internet image [seems identical to Wikisky DSS2] @ https://coraskywalke...aldebaran32.jpg shows the object near centre of the lower left quadrant.
I hope to reimage the area soon.
What does the Forum make of it?
